Hey everyone! Just a quick recap from last week: we've removed the LST bands and are letting the plants grow freely. They are looking fantastic and have developed a very dense canopy. 🌿 Now, we're at a bit of a crossroads regarding when to start the flowering phase. The back three plants from our second grow are only 23 days old, and I’d prefer not to have any plants outside the tent. Today, we're changing the light cycle from 20/4 to 18/6. This will give the plants more time to rest, which should help them grow even stronger. 🌱 The 18/6 cycle means 18 hours of light and 6 hours of darkness, providing the plants with more downtime to recuperate and grow. Excited to see how they respond to this change! Day 45 (First Grow): Hey everyone! Exciting update: we’ve built a SCROG (Screen of Green) net for the plants! 🌿 For those who don’t know, a SCROG net helps to train the plants to grow horizontally, which maximizes light exposure to all parts of the plant and promotes more even growth. We're using it with our six plants to ensure they all get plenty of light and develop a uniform canopy. We've also placed a hygrometer among the plants to measure the humidity between the leaves. We've noticed that the humidity sometimes exceeds 70% in those areas. Do we need more fans, an intake ventilation system, or would a dehumidifier be a better option? We’re leaning towards adding more fans to improve air circulation, but we'd love to hear your thoughts and suggestions! Day 46 (First Grow): Hey everyone! Exciting news: the plants have names now! 🌿 This will make it easier to identify and keep track of each one, especially if they get moved around. It should also help you all follow along more easily with the pictures we post. Stay tuned for more updates as we continue to watch them grow and thrive!

Light off for 72 hours and screw into the plant stem at the same time

Hola de nuevo amigos ✌️🌞 Una semana más que óptima para esta belleza de planta, esta resistente y esbelta cepa se ha adaptado genial a las condiciones que tengo controladas de cerca con Trolmaster 🤜🤛💐 La planta apunta hacia arriba con energía, sus tallos son muy fibrosos y resistentes, el ventilador apenas la hace mover y recibe la luz de manera óptima. Siete días antes de las fotografías le apliqué una dosis mínima de Power Buds de Plagron ya que he visto en mis cultivos anteriores que acelera la producción de tricomas repentinamente ✍️, se puede combinar (al final) con los nutrientes de la línea organomineral de GenOneEleven sin problemas y no afecta al pH o la EC 👌 El aroma de esta bella planta es fuerte, pero aún ni la he molestado demasiado como para definirlo 🤭☘️ Un saludo grande para todos y nos vemos en la siguiente!

This grow is going really great. Not one problem have I encountered. Really love these seeds from RQS👌👌

Plant is 21 cm high because of low stress training. The length of the stem is 34 cm. Day 43 ☁️🌧️☁️🌧️⛈️ 14 - 17 degrees, humidity is about 72 % I prepared some simple comfrey manure for the next weeks of flowering. It‘s rich in silica and tannins and essential minerals. Mostly all fruit vegetables and flowers like it, so Tropicana will have it as a tee or head fertilization, as well as in her water mixed 1:20 and 1:5. Same procedure like with tomatoes or peppers. No watering in the next days. The soil is soaked with rainwater. The growth is a bit slow in the last cold and rainy days but the flowers look nice.😊 Day 44 ☁️☁️🌥️☁️🌥️ 14-20 degrees and humidity is around 64 % Day 45 ⛅️☁️🌧️☁️🌧️ 13-21 degrees and humidity is around 69 % The flowers started to stack. The soil is too moist but I can‘t change here a lot. Don’t need too water in the neuerer Future and aafe water for late summer. Think when I can drink my next relax tee - take same leafs. Now Tropicana needs all of them for transpiration. Heavy pots. Too wet springtime. 🌧️☔️ Day 46 ☁️🌥️⛅️🌤️ 13-19 degrees, humidity is falling. Windy. The flowers are stacking up. 🐞🐞 did their job and left. With them the mites disappeared (hide). But I found some eggs under the leafs off all three of my cannabis plants. So I will have an eye on this… balcony problem! Wait some more days and bring a couple of 🐞 again. Found some magnifying glass and it suits with my camera lens. Day 47 🌤️☀️🌤️ 11-22 degrees, humidity 89 % and getting even higher this night. Took out two leafs. Day 48 🌤️🌤️🌤️ 17-23 degrees, humidity 89-43%, falling! Tropicana got a liquid breakfast this morning made out of two liter rainwater with 20% ready comfrey manure which is rich in silica and tannins and essential minerals. Be careful with liquid manure as you should have experience in giving high doses. Never more then 20% of the watering on moist soil and never give it pure and after the water. It will burn the roots. This is very fresh, only one week old and not too concentrated. Next week I will give maybe 10%. So, we just enjoy a sunny morning with a healthy breakfast and coffee! 😊

The girl is fantastic :) she looks strong, healthy and happy :) next week, I will defoliate her to give energy to the flowers, and at the same time improve air circulation closer to the stem :) everything is going smoothly and well :).

🌱🌞🌱Week4🌱🌞🌱 Bruce is much smaller, LST is almost completely tied to the ground, but looks super healthy. All the side shoots have now been directed and I hope that she will now grow nicely upwards 😅 Sherbet is my queen in this grow so far 🌞 It's just fun to watch the beauty grow. To start the fourth week, I removed some leaves today and directed the shoots in the right direction, otherwise Brucie will soon be completely overgrown 😂 but hopefully it will also have the effect that the good energy of growth will now go in the right direction.... I'll be surprised. Now she looks like a beautiful chandelier 😎

Another week down a whole week of 12/12 and I won’t say she’s stretching yet, I would have thought ild see son pistols by now but no. A few new things to add to the list of nutrients, this week she’s had a heavy top dress. Reaper, soil candy, and barley to kick start bloom, grow plus to make sure she has enough to stretch properly and the knf. Which I’ve add fermented fruit juice to now for bloom, Fermented fruit juice - I’ve gone hard to ferment this properly since using shop bought fruits, Bananas for potassium, blackberries and blueberries because that’s how I imagine a moonberry would taste 😂 I know it’s no going to influence the terps but still LAB for microbes and jsm ( leaf mould and potato in water to collect microbes in the water) And finally molasses. This brew took about three weeks. The light stayed the same high flipped to 12 hours and turned up to 75%. She will stay there until the plant reaches 30cm from the light. I thinkkkkk that wraps this week up might be a bit boring from here on out work wise butttt will be exciting watching her blow up, till next week. Let’s get it 💪🏽

68h light off

My first grow was a rollercoster ride of emotions. Hope and worry have taken turns throuout the whole grow. Harvest day has finally come. I'm not so happy about the color of the trichomes. There are still too manny clear trichome heads, but the overall apearance of the plants made me think that maybe the plants are not able to ripen completely. The color of trichomes hasn't changes much in the last 2 weeks. I've been flushing for 3 weeks now, so there shouldnt be much nutrients left in the soil. All the leafs are yellow and rotting. Since I had budrot on Plant #2, I am worried to get more budrot through the rotting leafs. So I decided to harvest now, in order to save what I have grown so far. Yield: Plant #1: 532g (wet with stem) Plant #2: 475g (wet with stem, missing main cola due to budrot) I expect a yield of about 100 g of dried buds.

May 19, 2024 Day 29 This week we focus on training. I'm debating on doing a couple different things to see what happens. I'm definitely tying down branches. But I may top one of the taller ones and train the branches out to see how different it looks than the other tall one. Sour Diesel A is now sitting the tallest at 11.5". Her branches aren't as long yet, but she's taller than B. Her stem is still pretty flexible, so I'll be tying her down from the top. Sour Diesel B has lost her place as tallest plant. She sits at 11.0" tall but has wonderful side branching. Definitely ready to tie down and spread out, maybe. I think if I top any plant it will be this one. She has 7 nodes now and she's definitely old enough for it. Also, her stem is really stiff now and I don't think I can bend it at all. So I may research topping. Sour Diesel C is the same size as D sitting at just 7" tall. Her internodal spacing is really tight still. I'm hoping she starts to grow soon. I will swap her and D out with A and B tomorrow. She has beautiful leaves with nice deep green. Super healthy. Sour Diesel D is actually spreading out her nodes now. She's still only 7", but I'm not expecting her to be super tall like the other 2. We'll see how tall she gets. But she has some nicely even internodes now. Great color. All 4 ladies got a half gallon of plain water PHed to 6.1 today. And all 4 drooped just a tiny bit and not for long at all. But that half gallon seems to have done the trick. No watering for a few days. I haven't changed the lighting yet as I still have other plants in the tent, but it will be changed soon enough. The DLI really should be at 30 mol/m²/d, but that's just not happening at the moment. The environment is looking great for these 4. The humidity is at 65% but the temp is a bit low. I'm running the tent at 73° because of flowering plants. I've been trying to get it to 75°, but then the humidity spikes. It's pretty dry out today, so in theory, my room humidity should drop. It hasn't, but it should. That may let me get the temp up to 75° without making it too warm in my room. Grow System Environment: Temp: 72.5° RH: 68.4% VPD: 0.84 kPa May 20, 2024 These ladies are looking absolutely great! Especially A and B. D is also starting to shape up. C is a bit lost. Maybe she needs to be moved to a different spot. I think I'll rotate her out with D. Sour Diesel A looks magnificent. He's growing very quickly and has a bunch of nodes. The branches are starting to stretch as well. Looking good. I can start training anytime I want now. I think I'll start tomorrow with this one. Sour Diesel B is beautiful with her long side branches and a healthy green color. I should start training her today, but I'll also wait for tomorrow. Sour Diesel C is needing a bit of love. Not really much I can do with the space I have available at the moment, but I think I'm still able to manage. She still looks healthy and happy, just short nodes. Sour Diesel D is coming to her own now. She is showing great signs of stretching and spreading out those nodes. She also is starting to grow branches out finally. Very healthy plant. No watering today. Obviously, because they were watered yesterday. I'd say a good 3 days before needing another watering. I'd also like to mention that I'm already seeing pre flowering signs. Little white pistils coming from where the bud sites will be. So I'm thinking these ladies are in pre-flower, or very close to it. It may take another week for them to really show it, but by then, they should be pretty big and alone in the tent. The lighting is the same, but they are starting to grow into it. Well, at least A and B are. C and D will need a bit of a push when the tent opens up for them. I'm also thinking they will need risers to keep up with the other 2. The environment is perfect for these ladies. The temp is a little low for them, but nothing crazy. 74° but the humidity is still at 65%. So we are looking good for now. It should stay this way for the next week or so. At least until I get the other 3 flowering plants out. Grow System Environment: Temp: 72.6° RH: 67.7% VPD: 0.86 kPa May 21, 2024 A bit of a to do today. Training happened and so did pics. And some well needed environmental adjustments. Sour Diesel A is a perfect candidate for tie down LST and so right was I. She got a perfect 90° bend just to the edge of the container. I couldn't be happier with the result. Being as tall as she is, the bend only went about half way down the stem and didn't touch the angle of the base. Perfect. Unfortunately, I can't tie down the side branches yet as I don't have the space to do so. But I can let the whole plant catch up before I do another tie down. I might just pull the branches out around the base of the container to make sure all the space is taken up by bud sites. I should t have a problem. It will be slightly different from what I normally do, but I can adjust when the tent frees up. This ladies has started pre-flower now. I can't wait for the stretch to really start. Hopefully it takes a couple more days. I still have to pull another plant. Sour Diesel B was also a neat perfect candidate for the top bend. She is much stiffer and the bend only went down about a quarter the way, but it's still a perfect 90° angle and still just inside the edge of the container. That will be a long the edge by tomorrow. She is also in pre-flower now. 31 days makes total sense, so I'm happy. Her side branches are beautiful and long. I'll need to start tying them down soon. No clue how I'm going to manage it with such little available space for now, but I can always adjust when the tent clears out and there's plenty of space. Sour Diesel C is growing, but not as tall as one would think. It's just the position in the tent they are at. They are under 3 other plants and not getting enough light. As soon as I move the Tropicana Cookies out in a couple days, I'll be able to give them as much light as they need. I may even have to raise them up a bit. We'll see how things go in the next few days. Sour Diesel D is another story. She isn't looking to shabby at all. Nice spread of nodes, she's starting to stretch a bit, but nowhere near as much as A and B. But she still isn't much taller than C. I'll be watering all 4 ladies tomorrow I think. Each with a half gallon of water. I'm trying the wet and dry method, kinda. I'm giving a little extra water than I normally would and waiting an extra day. So far it seems to be working wonders. In a couple weeks, they will all be bottom fed for the rest of the grow. I've found that 3 gallon containers take in about a third of a gallon a day during peak flowering time. Maybe a half gallon a day, depending on how big the plants are. And how many roots break through the bottom of the container. I like the bottom feed because the ant takes what it needs and I can build a nice crust on the top soil for pest control and protection. The bottom feed wick system works wonders and keeps the containers between 45% and 55% saturation. It seems to be on point for cannabis. I may be wrong, but that's the reading I get for all of my plants. Especially the bigger ones. As I said earlier, the environment got some much needed adjustments today. The central air finally kicked on and that blows out super dry conditioned air. Very clean. And keeps the humidity down. So the humidity didn't drop as low as it should have, but it takes time for the moist air to be forced out. At least the tent is at around 60%. And dropping slowly, but dropping. At this stage, I think it should be between 55% and 60% humidity. the temp is staying at 75°. A great temp for all ladies in the tent. Grow System Environment: Temp: 72.7° RH: 62.9% VPD: 1.00 kPa May 22, 2024 Not much going on today. Made some training adjustments and will be watering tomorrow. Also, there's about 50 days left in the grow according to Seedsman. They say the flowering time is around 45 days. Add a few for pre-flower and there we have it. 50 days. Let's see how well I do for the next 50 days. I hope I can harvest by then. Sour Diesel A is looking fantastic. She took quite well to her first bend, so I pulled her down just a little bit more. If course now the side branches are growing quite quickly. Very healthy and happy plant. Sour Diesel B also looks amazing. Her side branches are all getting nice and long with really good internodal spacing. She took swimmingly to her first bend and as I did with A, I pulled her down a little bit more to keep the main top at 90°. As soon as space frees up, I'll tie all the side branches down to get a nice canopy going. Sour Diesel C is beginning to stretch out a bit. The nodes are finally spacing out which of course means the stretch is just about to start. Huge leaves. Also overlapping the other 3 plants. Sour Diesel D is starting to look really good. Still shorter than A and B, but catching up, especially now that they were tied down. The light will be dropped in a couple days and I'll be adjusting the DLI. It should be at 35 mol/m²/d and it's not. So I have to lower the light about 12" and drop the power down to 60%. The environment is great for these ladies. So far we have hit the mid 50s% humidity and are at just over 61% now. The Central Air is off for now, but will kick on anytime. Once that turns on the humidity will drop again. Currently I'm stuck using my portable AC that blows wet, room temperature air that jacks up the RH. The temp is still pretty good at 57°. Grow System Environment: Temp: 75.7° RH: 59.4% VPD: 1.20 kPa May 23, 2024 I was going to water today, but I was really busy with my last Tropicana Cookies wet trim and harvest. The soil moisture content is around 33%, so it should be fine until tomorrow. Speaking of harvesting, now that the Tropicana Cookies are both gone, I have plenty of space for now. They still need to be tied down and trained. I'll be harvesting the two Banana Purple Punch's in a week so when those are gone, there will be plenty of space to really train them and get myself a really nice canopy. Sour Diesel A looks great! Her branches are reach straight up though. Definitely because of the tight quarters and light intensity. Now that she is under the light and not impeded by another plant, she should start stretching even more. Sour Diesel B is looking amazing as ever. As with A, her branches are sticking straight up for now. That will be adjusted starting in a couple days I think, if not tomorrow. Sour Diesel C is starting to fall a bit behind. Not by much, but a little bit. I'm sure she will bounce back in no time now that she has plenty of light. But I'll keep an eye on her. If she turns out smaller, I still have the 2x2 in a couple weeks. Sour Diesel D looks great! She is catching up to A and B in girth. Great internodal spacing and side branching is looking good. I expect her to take off with the extra space now and more access to the light. The lighting needs to be checked and I'll do all that tomorrow. Along with the watering and possible LST. The environment is finally at a reasonable level for these ladies. It was kinda cool today, but the humidity is down to 52% and is just right for this stage. The temp was about 72° for most of the day. But will climb back up in a matter of a few hours. Grow System Environment: Temp: 75.1° RH: 60.2% VPD: 1.15 kPa May 24, 2024 Watering day! Each plant got a half gallon of plain water PHed to 6.1 from the top. The last Tropicana Cookies is now out of the tent and now there's plenty of space. I have them staggered with A in the back then D, B then C. Not too much more space, but enough for me to pull branches out a bit. Honestly though, they are making their own level canopy, so I might do some very light training this run instead of heavy. It all depends on how they look in about a week. Speaking of in a week, I'll be pulling the 2 Banana Purple Punch's out in a week. That opens the whole tent up and each planet gets their own quadrant. I think I have the timing right on this. Hopefully I'm right and these ladies will be able to be trained more. Sour Diesel A looks great. Her single tie down increased the height of the side branches and she is creating her own flat canopy. I'm definitely going to have to pull branches apart and tie them down soon. Hopefully I can hold off for a week. Sour Diesel B has a wonderful canopy going. Her branches are all falling into place around the whole plant. Opening up each top for all the sunlight they can get. It's pretty impressive. I'll definitely have to train her down soon. I may have to in less than a week as well, so this might make things pretty tight again. Sour Diesel C got a perfect top bend today. Her branches are a little behind and she's making the standard Christmas tree structure. So this bend should fix that and give her the start of a nice level canopy. Sour Diesel D is coming along nicely. I accidentally broke one of the main stem fan leaves. No big deal, but it was still a mistake made. Oops. Her nodes are starting to spread out a bit, but she is definitely a compact plant. It's too soon to tell how big she will get. So far it looks like she'll be stretching, so who knows. Maybe she'll get to 2 ft. The plants have grown into the light and will need an adjustment in maybe a week. I'll be checking the DLI later today. I'm pretty sure they won't need any changes in the immediate future. We shall see. Update: I checked the DLI and got a reading of 24 mol/m²/d. Much too low for these ladies. They should be around 35 mol/m²/d. I'll have to figure out a way to increase the intensity without hurting the other plants in the tent. They should grow right into it though. Now that stretching is about to begin. We shall see. I'll update again if I figure out a solution. The environment is back up to 59% and the temp is around 76°. It's ok I guess, but I'd really like it down to about 55% to 50%. 50% would be great for this week to be honest. Grow System Environment: Temp: 72.9° RH: 56.6% VPD: 1.17 kPa May 25, 2024 It's the end of the week and the weather sucks! Its rainy and humid out. Really humid. So the tent is now suffering. Sour Diesel A looks really good. A little sparse on one side for branching. I am not a fan of when this happens. I need to pull out about 4 branches to get an even spread and I can't at the moment for two reasons. Firstly, there just isn't space yet to spread the branches out as needed. Some of the branches are fairly tall, but the top is still taller. It's really stiff so I can't bend the top down again. Maybe during the stretch I'll be able to, but not at the moment. The second reason is side branch size. I have to move 4, but only 2 of the branches are long enough so far. Sour Diesel B is looking absolutely amazing. She has a level top and an even spread as well. I technically shouldn't have to train her, but I'm going to as soon as she has the space. Sour Diesel C looks really good. She took perfectly to the training and has a perfect 90° bend on the top. The rest of the canopy is a little behind, so I may have to pull the top down again tomorrow. By then the side branches should have caught up. Sour Diesel D is going to be my untrained plant for this grow. I train all my plants, so leaving this one alone is nerve racking. Lol. She looks pretty good. Side branches aren't very far behind the top, but it's definitely going to bush up and maybe grow fairly tall. We shall see how she goes. Maybe I'll have a 3 oz top. The environment is a mess. The temp is at 75° which is fine, but the humidity went back up to 60%. It's not bad for now, but when they hit flower, the humidity needs to go down to 50%. 55% would be ok, but I'd rather 50%. Grow System Environment: Temp: 75.1° RH: 55.2% VPD: 1.30 kPa

Week 9 has been a good week, there responding well to the last two days completely Outside overnight now. Maybe in the ground next week?.

Looks alright

Honestly guys she is amazing but bit slow flowering like northern light Shame I have to cut 3 main cola top coz to close to light and she couldn't photosensitive and that's cause slow flowering so I decide to cut 20cm from 3 main cola 😢😢hope that work Well I figure out why she won't flowering coz she too big for 6L pot thats why so I transplant bigger plant into 25L fabric pot and next day she start developing bud so happy 😊

📆 Week 5, 19-25 May 2024 19-25 May - Observed and let the plant grow. 📑 The plant is very compact with big, wide leaves, typical with Afghan varieties. The spacing between nodes is a good 1”. What I do is tuck the big leaf under the developing branches rather than cut them off early in this stage, to help the plant produce maximum energy. I also snip very low sucker shoots that do not have a chance to keep up with the plant, which is only a few. This keeps all the growth focused on the top of the plant for now. This will probably be her last week of what I consider veg, as she is starting to show more bud development. 🍶 19 May nutrient solution changed 🍽️ 19 May feeding schedule updated 💧 Using reverse osmosis water with EC/TDS at 0 🐉 Nutrient solution EC 2.6 at 70 degrees F 🔆 Light power at 50%, DLI 28 canopy coverage at 18hrs 😤 Using PYPABL, Air Pump, 400GPH That is it for this week. Thanks for the look, read and stopping by.

The temperature and measurements under grow conditions are all averaged for the week. The pH listed in grow conditions is the soil pH. Any listed nutrients are ml/gallon of soil. Day 1 we have lots of sunshine and temperatures in the mid 80's F. I watered today about 1.5-2 gallons per pot directly from the hose. Well water is 7.6 pH and about 50°F. #1 and #2 got topped today. #2 was topped in the evening at 6.30 p.m. I waited for it to get a little more space between the nodes, so there's a bit of stem above the node. This will help it to not split. Day 2 we had thunderstorms and rain in the morning followed by sunshine. The #3 plant was topped today. Day 3 we had lots of sunshine, temps in the mid 80's. That evening we had thunderstorms and rain which became severe that night. Hail was in the forecast but we missed it 🙏. I noticed the number 1 plant was growing crooked. I had moved the pots to get more sunlight and the one was uneven. I did some moving and adjusting today and hopefully it will straighten up. Day 4 we had rain in the morning followed by rain and thunderstorms intermittently into the night. Day 5 we had rains early morning and then cloudy most of the day. We have sunshine in the forecast for the weekend. 🙏🙏🙏 All pots were top dressed with 50ml of ferrous sulfate. Day 6 We had sunshine in the morning and afternoon. Clouds began to move in about 3.30p.m. Suddenly about 4:00 p.m. we had a severe thunderstorm that produced heavy rain and grape sized hail. Thankfully the hail only lasted a few minutes. There was some damage to this group, but only leaves. Day 7 we had sunshine, but cooler temperatures with highs reaching low to mid 70's. The plants began to show some Interveinal chlorosis in the new growth on day 5. I checked pH and it's above 7 in the pots. I added ferrous sulfate to counter this. On day 6 I noticed the #3 plant falling behind from receiving less direct sunlight. I've run out of space to accommodate the suns procession. I moved it to a better place for it to receive more sunlight. This week produced challenges. The topping was successful, but the position of the plants prevented some of them from receiving maximum direct sunlight. It took a few days to notice the affect on growth. We did not have much height gained this week. There was the issue with rising pH again, but this was promptly dealt with. We survived the challenging weather. Overall a successful week as lots of downward root growth was achieved. This will be evident next week as plants shoot up.

Growing fast! So my goal is to have a few main branches, and make them as thick as possible. Want to see if this creates larger colas. Added silica for 1 feeding so far. The stuff raises PH quite a bit FYI. Added it first before all other nutes. Also feed Recharge a day after watering while soil still moist. Stress techniques - - Super cropped a lot more. I would bend harshly without breaking in between each node just before watering. Did it on all stems at once, entire plant looked so sad but perked right back up later in the day. Maybe I'm triggering it's survival mode because growth seems to speed up after initial stress. - I keep taking off new nodes as they appear to keep the growth structure I want. I'm taking something off almost everyday and might be the most stressful thing I'm doing. - The tight ring around the base of the stem is showing heavy scaring and buildup. I'm keeping it on so it stays tied down, and to see how the plant deals with it. I like to think the plant thinks it's bugs attacking its stem. I have noticed the main stem hardening up. - First week I did a heavy feeding. Want to see how far I can push the nutes without burning the tips. No tip burn yet apart from some light stress (maybe). Crazy how this 100 watt light is doing. You think 100 isn't enough but it most definitely is. At least for 1 plant in tent.
