Really love a set of scales to keep track of weight too. pH and EC are both critical for thriving plant health, but temperature also plays a pivotal role in achieving optimal growth. It also happens to be the fundamental parameter that's most commonly overlooked. When you think about temperature in the context of a growing environment, you could be referring to the temperature of the air around the plants or you could also be referring to the temperature of nutrient solution or irrigation water, which will affect the root zone temperature. While air temperature is important, for the purposes of this piece, I'll be focusing on root zone temperature and its effect on nutrient uptake and overall plant health. That's because a plant's root system is the location of two essential chemical processes: water and nutrient absorption. In each of these processes, having the correct root zone temperature is paramount for these to occur efficiently. In a nutshell, root zone temperature will affect the rate at which your plants are able to absorb nutrients. If you let your root zone temperature remain unmonitored and uncontrolled, this could lead to disastrous effects on your overall crop yield. Nutrient absorption is largely driven by chemical processes, which take place in your plants' roots; the efficacy of these processes is determined by the temperatures to which those roots are exposed. Once your root zone temperature moves out of its optimal range, the plant will not be able to deliver optimal levels of nutrients and water. Ideally, you should aim to have your nutrient solution or irrigation water temperature at around 18 – 22 °C (65 - 72 °F) to ensure optimal nutrient and water uptake. In addition to having an effect on nutrient absorption, your root zone temperature also affects oxygen availability and solubility. If your water is too warm, you could risk starving your roots of oxygen as warm water cannot hold as much dissolved oxygen as colder water. On the other hand, if your water is too cold, this could shock your plant roots, decrease plant metabolic rates, and stunt plant growth. Peace out.

Donna Jo is still being watered; -Tuesday with full gp3 (green plant 3 part) plus Cali mag by General hydro PhD to 6.2 roughly 2 litres - Thursday get PhD Cali mag water and Only 1 litre at most. Try not to water Thursday unless she is to dry to make it to Friday -Friday full gp3/ Cali mag PhD 2-3 litres -Sunday full gp3/Cali mag PhD 2-3 litre -Monday/Wednesday/Saturday no water. This week had a pretty major change not just in flower production, but also decided to change tent set up as well. Changes to the tent included ditching the 600w led and the 2x 2000w garbage led lights (i call bs on manufacturer saying they are 2k) These 3 lights are now out and we have stepped up to cmh 315w. Should have bought this cmh 315 right off the hop and not spent the money on led. Now going to cmh the tent run way hotter and has required other upgrades to keep from overheating. The duct system was dual t4 cloudlines running one in and one out off the same control module has now been changed to a T6 cloudline exhausting with a t4 feeding cool/fresh air. Tent jumped 9 degrees with cmh 315 so had to also add the overheat back up plan. Put a 6” inline duct (can fan pushing extra 200 cfm) along the exhaust line closer to window exhaust point which is plugged into an ink bird plug and play thermostat set to 82. This just helps the T6 do a better job with less noise. With these changes I feel way more confident of yielding a higher gram/plant ratio. I believe if you look at last weeks pictures and compare to this weeks you will probably agree with me. You decide .......😀

High GD community, Week 12, Haze doing very good. Her sativa genes push her to grow big. But the stems are a bit thin. Hst and LST will help those branches get more solid. She had a hard time in the beginning of her life, but now she is definitly on the good flow. Thats it for this week boys and girls, Thanks for reading and passing by and 💚💚💚👏👏👏👍👍👍 for Marshydro leds.

Hey guys, what's up? Here's an update on a new week of vegetative growth for this beautiful Strawberry Cola Sherbet from Sweet Seeds, which is developing quite well, although I had to interrupt fertilization due to a small root blockage, a mineral buildup because the pH meter has been miscalibrated for some strange reason and I had to water at least twice with an incorrect pH, which has caused the plant to be unable to absorb these minerals. I have already watered with distilled water, adjusting the pH to 6.0. I hope it will return to normal within a week and I will fertilize again gradually, as I expect it to bloom in 1 or 2 weeks. I will keep you updated and you will see the progress. A STRONG HUG FUMONES,💀😍

These gals are still recovering from getting chopped and pulled down. Almost sounds like bdsm. But the lower branches are starting to come in. They are beginning to get real green and possibly show lockout. Not a fan of the tiny ass pots and coco loco soil. Day 26: I snapped a branched/topped stem on one of them. :/ had to trim the wilting leaves off that side and hope it heals back

Trying to go back and see everything I did and I’m pretty sure it was the two nights of not having a heater down in the basement I live in Ohio. It gets really cold at night and then switching environments from veg tent to flower tent the combination of me over feeding and all of those I think is what has stunted her, going to give her another couple days to see if she jumps out of it 🔥💯

I just tried a new fertilizer. It turned out to be more than expected. Excellent.👍👍👍

Beginning of week.. Still waiting on these damn pistils to finish up.. Trichomes are still looking pretty clear for the most part.. Plenty of milky but Id rather have a little amber starting and still seeing mostly milky/cloudy.. Not in it for the clear trichomes lol.. I prefer the couchlock effect more anyway. I have read that i stead of counting flower as the day of flipping to 12-12 because outdoor growers have to wait till they see flower starting.. Which can take up to 2 weeks after flipping to 12-12.. So I guess adding 2 more weeks to what I thought.. So.. Expert Seeds say the longest she could take is 64 days.. We are beginning week 7 of flower if we look at it that way then.. Which would mean that today is only day 49 or so... 63 days will be about 9 weeks of flower... Some shit like that.. Ugh. I should keep better track of the days lol. I could just do it by the weeks.. But I feel like this strain is already going way longer than she should have. I can tell the end product is WORTH THE WAIT for sure!!! .. Later that day.. Ok so I went ahead and mixed a batch of pH'd water with some General Hydroponics FloraNectar Fruit-N-Fusion.. 1qt of water with 2ml of the mix... I'm hoping to stop the yellowing from spreading to the buds at this point since I need to push her another 2 weeks, at least! Hopefully it will help the terpene profile also.. It smells like it should lol.. This stuff smells delicious.. I cant wait to see what it does when used throughout an entire flower cycle.. Not all stupid like I did this time lolol.. Just not trying to add anymore salt nutes.. Or any nitrogen I guess since its getting closer to harvest.. I wish I would have been using it the last 2 weeks at least.. Oh well.. Live and learn!.. Mid week.. Ive been still watering with Flora Nectar FruitNFusion in pH'd to 6.1 tap water during the day.. And just pH'd to 6.2 tap water that is left in the fridge to be able to water with cold water at lights out.. Not doing much to this strain.. But my other strain is turning super purple! Its so pretty! Im actually trying to create some feminized pollen from a cut from this plant. Its such a heavy yielder and super dank asf.. These nugs could break rocks lol.. Rock fucking hard.. Anyways.. Just waiting till she's ready to be harvested! End of week.. She has fattened up some this week. I should have never flushed so early lol. Live and learn tho.. Smells are lingering alot longer than they were before.. Now the whole house smells everytime I pic her up for watering and daily inspections lol.. She is slightly turning colors.. Reds.. Pinks.. Some purple.. Done with this week.. On to the next!...

El lec lo he bajado a 245w por la temperatura.

two week behind on this journal haha

TOTAL COST : 138£ - Electricity usage - £8 Buying the Grow lights - £54 Buying the Nutrients - £45 Buying Pots (x3) - £16 Tools - £5 Soil - 10£ I should say I had the nutrients for over 2 years so I’m using the price for that initial purchase. They were used in all my other gardening endeavours such as tomato's, strawberries and chillies, I had great results with BAC and Nutrigrow but they are somewhat pricey. You might find some cheaper alternatives if that figure puts you off. - 31/05/26- This plant blew my expectations, from seed to harvest she was amazing, developing faster than expected at all stages, with keep in mind very limited resources, still she was a productive, over achiever and definitively one of my best grows of all time! But harvest day is upon us, her tricomes are in that sweet spot for Milkey/small amounts of amber! So Now is the best moment to harvest! It’s always a bit emotional but I like to play some calm peaceful music like a final concert dedicated to the plant right before I put her to sleep! And start drying her. I like to make use of all the leaves brewing them into a tea. I’ll update the dry weight later! 03/06/26 - This is great I got the dry weight back and got 10grams of dry sticky amazing weed, this is better than I initially expected, I had in mind that I would be lucky for 8 grams! But now I'm curing it and developing those terpenes flavours which should enhance the experience! This is modest quality and I couldn’t be prouder

Things is getting big and fat in here. Flush is on for 2 of the blueberries. Last one is abit behind. Straight water from the tap. Very smelly in the tent when i open it.

Muy buena genética, me quedé con el pheno 1, ya que tenía más resina y un mejor terp para mi gusto. Buen híbrido no te deja superaplacado y ofrece un efecto cerebral eufórico.

17.11 Lampe auf 100% PPFD 850-950. DlI 38 - 41. Vpd 1- 1.1. 1.5L mit 1.9 Ec. 14.11 gute erste Blütewoche gehabt. DLI auf 33-36 erhöht. Ernährung bleibt erstmal gleich bis auf ne kleine Steigerung beim CalMag. Ich scorg wieder im Verlauf der Woche.

Week 3 nothing new just LST and water daily

Exelente experiencia, muy resistente, un sabor exelente

week intel: everything is perfect! stresses : just a little E.C stress around 1.7 once a week feeding: i feed them 3 times this week with this order : day 1 : i feed them heavy with silicate +base nutrients(calcium & micros + Bloom) about 818 ppm - 1.7 e.c to cause a little stress. day 3 : i feed them low dose of Feeding Booster + Karbo Boost around 382 ppm - 0.7 e.c to let them recover a little but not fully recover still a little stress will caused. day 5 : i feed them with low dose of Top-Max + B-52 around 250 ppm - 0.5 e.c to let them recover the stresses to get ready for another stress next week. guide of the week : know your plant tolerance limit of E.C stress once you saw the very very little yellowing on tips of leaves , that's the sign to don't go further , never reach that limit if you want a high quality buds, in my case tolerance is 1.8 and i'll reach to that level only once a week to cause precision stress , love your plants and have a happy growing!

May 10, 2024 A new week and more flushing. Both ladies look really good. Tropicana C is way too heavy for her branches. It's good and bad. It's bad because they are flopping all over. And it shows how weak these tops are. It had to be my nutrient regimen. It's good because it shows the buds are dense and heavy. Tropicana Cookies has significantly stronger branches and can hold a lot of weight for the size of the buds. I could just be a tight fit with all the buds up and down each top. Who knows. They are starting to lean a little bit, but not too bad. Her buds are almost all purple top to bottom and the leaves are getting lighter and lighter throughout the plant. She's covered in trichomes. From what I can see, there's not nearly enough amber trichomes on the buds. Very soon though. I reactivated her wick system today. Her container was about half the weight as it was yesterday. Maybe now that it's not saturated anymore, the wick system will provide what it needs. We shall see later today I think. The lighting for some of this week will stay the same. I'm just waiting for the other 2 plants in the tent to start their flush. Then I'll drop the power down some. Most likely to a DLI of 36 mol/m²/d. We shall see. I'm also curious if it will actually do anything. They are autoflowers and light doesn't really mean much. Just as long as it's on and the right DLI, it should be fine, right? Anyway, I'll drop it when the flush starts anyway. I want to see what happens. The environment is looking a little better. The humidity is lower at 54%, but still way too high. At least it's below 60% finally. But 54% isn't much better. The temperature is pretty good at 76° during the day and 67° at night. I still can't get it down to 66° at night, so 67° will have to suffice. However, there is about a 10° difference between lights out and lights on. Grow System Environment: Temp: 74.1° RH: 54.2% VPD: 1.29 kPa May 11, 2024 Watering day! Last watering of the grow. I'll let them dry out from now on. It should be like 4 days before they are dried out. Tropicana Cookies looks so close to being done. Her fade is spreading and I'm guessing another 3 days? Maybe less. There is so much more purple now. Ite absolutely beautiful. She definitely will need a trichome check daily. Tropicana C has started showing purple finally. I'd give her another 5 days, maybe a week. I honestly cannot tell. I'll check trichomes tomorrow and every day afterward. Her buds are definitely getting heavier and some even look fatter. She's definitely not quite ready, but super close. The light power will be dropped in a couple days down to a DLI of 36 mol/m²/d. Not much else for that. The environment is still kind of a mess. The temp is fine at 75°, but the humidity is still high at 55%. I even got the temp down to 66°. So that's good. I'd like to keep it there for the rest of the grow. I'll also try to drop the temp during the day to help bring out more color. It will also help with keeping the temp low during the drying period. Grow System Environment: Temp: 73.0° RH: 53.6% VPD: 1.27 kPa Update: I ended up checking the trichomes anyway, and i think I know when they will be done. Just an estimate, but I think a good one. Anyway, Tropicana Cookies should be done in about 3 days while Tropicana C should take about 5 days. I may wait and harvest both at the same time. Or in between and harvest them in 4 days. Tropicana Cookies just needs more amber trichomes. They are almost all cloudy. Very few clear, but only about 5% amber. Tropicana C on the other hand, has a bit too many clear trichomes and no where near enough amber. 5 days should do it. 4 might be a little early, but that might be the only option. We shall see in 4 days. May 12, 2024 Not much going on today. Tropicana Cookies had a soaked bottom again, so I removed 1 of the wicks. So there should be about half the water going in now. She's definitely not thirsty. So very close. Anyway, she is fading quite nicely and I think she will have a whole bunch of beautiful colors. Lots of purple and some nicely fading fan leaves. Light greens, yellows a tiny bit of red. But not there yet. Tropicana C did not have a soaked bottom today. She never does. It just tells me she is still thirsty. Which also tells me she still has some time left. Maybe 4 to 5 days, but I may harvest her in 3 to 4 days. It all depends on how she looks. I got some trichome pics today. Just one for each plant, but they were the best I could get so there you have it. Anyway, Tropicana Cookies looks very close. More amber trichomes, more cloudy and much less clear. Tropicana C still has a bit too many clear, but definitely has more cloudy. Not too many amber, but more than yesterday. I still plan to drop the DLI down to 36 mol/m²/d in a day or two. It won't really matter, but it's still important to note. It's for the other plants in the tent. The environment is a lost cause. I can still control the temp, but the humidity is still at 57%. I have the temp at 77°, but I think I'm going to drop it down to 74°. I don't think the humidity will go up with the temp change. And if it does, back up to 77°. I'll probably get the 74° mark, so all good. Grow System Environment: Temp: 73.9° RH: 55.6% VPD: 1.25 kPa May 13, 2024 Not much going on today. I checked trichomes and I think I'm going to harvest when Tropicana C is done. She should be done in a couple of days. Maybe 3 to 4? Maybe less? I'm supposed to be harvesting tomorrow, but I'm not sure I will. I'll check the trichomes again tomorrow, but both are there. Just a little bit more. Not too much longer though. I have 4 more plants ready to come in like ASAP. Anyway, the trichomes on Tropicana C are mostly cloudy now, with a few clear and more amber. Maybe 8% to 10%. Just a bit more. Tropicana Cookies is a bit further with next to no clear trichomes and the same amber as her sister. Roughly 8% to 10%. She will definitely be done either tomorrow or the next day. So I think it makes more sense to focus mostly on Tropicana C for harvest time. I really don't want to harvest an indica too early. Not to mention, the purple is coming through really quickly for Tropicana C. Tropicana Cookies has almost all purple buds. The very bottom of the plant still has mostly green with purple coming through just a bit. It's more like pink than purple. But the majority of the bud is green. These are the underdeveloped buds. Not even worth of popcorn I think. That stuff will become concentrate. The light intensity will be dropped tonight down to a DLI of 36 mol/m²/d. Kind of pointless for the last couple days, but it needs to be done. The environment is driving me crazy. I can keep the temp at 74°, but then the humidity goes up to 58%. Much too high. Even opening the tent door only drops the humidity down to 52%. I'm going to need to drop the humidity in my room down to 35% somehow and maybe I'll get below 50%. This is ridiculous. Grow System Environment: Temp: 74.4° RH: 56.2% VPD: 1.24 kPa Update: I ordered a new dehumidifier for grow tents today. It should be here tomorrow. I'm guessing a lot of my problem with the humidity is my current dehumidifier. It barely pushes air. Cheap and well used. The new one is from Vivosun. A much more reputable company. May 14, 2024 Trichome day! Took a couple videos. The videos are kind of crappy. I hurt my back so I'm shaky. I removed the wick system completely from both plants. Tropicana Cookies was yet again soaked. Not as bad with just the one wick, but still soaked. Anyway, I pulled the wicks and emptied the reservoirs. Maybe that will help with the humidity. They should both be dried out in a few days. Just in time for harvest. Tropicana Cookies looks wonderful! Her buds are nearly black, with nearly black leaves. It's the darkest strain I've ever grown. Insane. She still has a day or 2 left to go. There's trichomes, but not enough. Hopefully 2 days will do it. Trichomes are mostly cloudy, a little bit of clear and not enough amber. Tropicana C is right behind her sister plant in the dark purple color. Her flowers and sugar leaves are getting super dark. Fan leaves are lights ing up, but not fading. I have a feeling she is going to need longer than I have been estimating. I also have a major issue with the side branches all around the plant. They are just laying down. Buds completely facing down. The branches are also super weak. I don't understand what happened. Back to trichomes. There's like 20% clear still and nowhere near enough amber. The lower light intensity doesn't seem to being doing anything, but I'm sure it's preserving the trichomes. Maybe even helping along the plants to finish up. The environment is still a nightmare. The temp is still fine, but the humidity is stuck at 60% again. The humidity in my room is higher than outside. I have the door open to help drop it, but it's not helping with the tent humidity. I have no idea how environmental science works. Lol. I wonder if I defoliate both plants a couple days early, what will happen. Wouldn't it put all of its energy into the buds and increase trichome production, like a last push? I'll research this and decided what to do by tonight. Grow System Environment: Temp: 74.3° RH: 59.2% VPD: 1.15 kPa May 15, 2024 Nothing going on today. Both ladies are about halfway there before completely drying out. I'd say another 2 days. I was going to harvest tomorrow, but I checked the trichomes and they still aren't there yet. Plus, I think the other 4 waiting to get in the tent still have time to veg before they overwhelm their containers. One of them is very close, but I don't think she will be a problem in the next 2 days. Plus I can always train her down. Tropicana Cookies is starting to lean more. Her branches aren't quite falling over, but they are definitely getting weighed down. She seems to have basically stopped fading. Still a lot of green leaves, but each top is essentially all dark purple. So this may be it for fading. Now I can only wait for her to ripen up. Hopefully 2 more days. I really can't push it that much further. Tropicana C is still behind her sister by a bit. Not much, but enough for me to be concerned about harvesting them together in 2 days. I guess I'll see how the 4 other plants are doing in 2 days. Maybe I'll wait 3. Who knows at this point. It's been 7 weeks, so it should be any day. I think the light intensity is making the smell stronger. Less intense light is keeping the trichomes nice and plump and filling with cannabinoids. So maybe it was a great idea to drop he intensity. The environment is still kicking my ass. I can't get the humidity to drop below 60% and now I don't have much control over the temp It's stuck at 73°. Not bad for this stage, but it's killing the VPD. It needs to be at like 1.5 kPa, but it's at 1.00 kPa. Super bad. No good. The night temp is still too high. The average last night was 69.1°. Much too warm for night temps. Maybe that's what is taking Tropicana C to turn purple. She's getting there definitely and should be the same color as her sister. They are the same phenotype after all. Grow System Environment: Temp: 72.9° RH: 63.0% VPD: 1.00 kPa May 16, 2024 The final day of the week and I think I need to harvest these 2 tomorrow. The 4 Sour Diesels I have in my 2x2 tent are starting to get bigger and will need more space very soon. Not to mention, they are in my 2x2 tent I use for drying. Tropicana Cookies is basically done. I didn't check her trichomes today, but all the buds top to bottom are purple. Lighter purple in the lowers, but those are popcorn and larf, so I'm not so worried. She also seems to have stopped fading. She's nearly dried out now. Probably tomorrow right when I need to harvest. Tropicana C on the other hand has her trichomes looked at today. Made a video and took a pic from it. Anyway, the trichomes are much more cloudy now and maybe 7% amber. She should go a few more days, but I still have the dilemma of the other plants. I guess it all depends on how they look tomorrow I guess. She hasn't started fading yet, but more purple is showing up everyday. That's another reason I think she could go a few more days. She still hasn't even begun to fade. She's about half dry, but if I have to, I'll add a half gallon of plain water tomorrow to see if she fades at all. I may have to harvest Tropicana Cookies tomorrow and then Tropicana C a few days later. I should be able to fit 4 more 3 gallon containers in the 3x3 with just the one plant gone. It'll be tight and I'll need to Tetris the shit out of it, but I think I can manage. One thing I haven't thought about until now is drying itself. If I have to harvest separately, the 2 to 3 day difference will mess up the dry for the first one harvested. I think? Maybe not. I have a plan. Instead of hanging them next to each other, I'm going to hang them on top of each other. So the first will be Tropicana Cookies on top and later in Tropicana C on the bottom. Theoretically, with this setup, I could control the humidity a bit better. When Tropicana Cookies is nearly done and needs the extra humidity for that even dry, Tropicana C will have brought it back in and I should be able to hold it around 60% for the rest of the drying time for both plants. Lighting doesn't matter anymore. It's served it's purpose and I could technically take one out now for a 2 day dark period before harvest. But if anything, I'll wait for tomorrow. I honestly didn't think about the dark period until now. Haha. Whoops. That may just solve problem entirely. I don't have to wait for harvest time. My other plants won't get too big and I can put them in the 3x3 more comfortably. I can also harvest both plants at the same time. Or, if I have room, I can place Tropicana C in the dry tent on the bottom while Tropicana Cookies gets hung up. I don't think there's enough space though. Anyway, I think the best course of action is to put Tropicana Cookies in the dry tent for a 2 day dark period and harvest both when Tropicana C is ready. Then I can see if there's a difference between lights all the way to harvest or dark for 2 days. Fun! The environment is the bane of my existence. The new dehumidifier is definitely stronger than the old one and more compact. I even left the old one in there as well. Both running at the same time can only drop the humidity to a solid 60%, but my room is 63% and I can't do anything about it. I also have the tent completely sealed off. I think it's helping to keep the humidity from climbing to 65% or 70%. I have the temp up a bit to 76° and 77°. Just to help a smidge with the DLI. The only thing I have an advantage with is my ari flow and spread canopy. There's 2 fans blowing around air and the exhaust. It should help prevent mold or bud rot, but with such high humidity for days, I can only imagine something bad is happening. Maybe not bud rot or mold, but the chemical composition of the buds? I dunno. I haven't learned that much. Grow System Environment: Temp: 74.8° RH: 62.8% VPD: 1.07 kPa
