One of two turned out to be a herm. Fucking autos. No matter how flashy the packs, no matter how many clicks a company gets, you cant escape the instability of products rushed to market First and last time I grow this strain, easy choice. Save your money, grow photos

A nice stocky little plant. She is starting to get that nice smell. Taking heavy feeding nicely and also now fattening up. Still no purple colours yet. I love this strain.

ok so everything has gone fantastic , no nutrient burns at all , and have been slowly creeping up the base nutrients , i have stopped the cal mag and now adding house and gardens bud XL at full strength these girls are now in full swing of flower and i bought a new ph stick this week , i have found when PHing the feed bucket that its best too have air stones in the bucket , add all nuts and then ph but do not use the feed that day as if you check the next day the ph is off again so i left it 24 hours after i add more ph down , and it seems too make the measurements alot easier and stable , i have bent down the main stems " without damaging them onto my netting too A keep the canopy all the same high so my lighting is covering all plants at the same distance and also it allowed the side stems too reach up too , i also was sponsored another new led light by kingbo this week so have added another 600watt led too the grow , so now have two 600's and one 900watt , and temps are still fine sitting at 24c lights on and 19-20 off , so am pleased with that , this lady is nice and compact and tight lots of leaves that I had too remove too open up her bud sites , stretch was also minimal ,

Alright everyone? So this week I decided to flip her into flower. Hopefully she won't outgrow the tent. I haven't heard very many people using Recipe 420 soil, but I don't have any complaints yet.

Day 63: Hi all , a productive week it has been this week. The #2 has been taken out for her 48hr dark period before trimming and drying. She jas so much frost onher dark purple and red buds now too. she will be trimmed later tonight so will post a few pics later. Gorilla girls #1 is so close to finishing now too. Her colours are starting really come through now she is maturing and her smell is so sweet and clearly pineapples too. Her yield should be ok bit being kept lower may have been a factor in her overall size. perfect for a low , cupboard grow. #3 is very close to #1 in terms of a finish, if only a few days behind . Shebis so much smaller but her finalnpushbjas bought her on par for the amount of decent sized buds that smell so sweet and are starting to brown off on the tops mainly. I won't rush her but she is close. #4 is still my sneaky favourite for appearance without doubt. She is so beautiful as a plant it will be a shame to cut her down. She is so covered in trichs now that she looks silver and red. At least another week I thinks to get the best from this lady. A brilliant example of genetics. Sweet cheese is also very close to her finish but at least a week jumping by the fresh looking pistils poking out all over her thick main. She stinks of fuel now too. I will be interested to see how much she yields compared to trained ladies. Well hopefully the next update will be to say they are all hanging to dry amd maybe 1 actually harvested. Until then . be safe and sane Growmies UPDATE. the #2 is now trimmed and drying....

Skunk apple runtz I'm probably only going to keep 1 of these guys seeing the 2nd just has really bad growth so far. I'm sad about this I made this cross out my last grow and was hoping for the better end of things. The other plants is decent but we will see I hope it has the growth pattern of the lit farms Rick bobby and the bud structure of the obama runtz I grew It's looking like a good start to a week the plants are strong they are getting to the point I can let the dried dry out completely. I'm thinking by the end of this week the plants will be starting to be sold. Last week I put all the plants into my bigger 2x4 tent with my medicgrow mini sun 2 the 500w version. Only a few of the plants were ready for that light. Seems like the only plants that really have good resistance and have a strong start are the weedseedsexpress.com seeds. Shout out to weedseedsexpress.com for the strong plants. I ended up putting all the plants back into my 2x2 tent with the 55w amazon light it has alot more blue light in its spectrum. It's kinda weird b4 I switched the plants to the 2x4 tent they were getting 220umol under my amazon 55w led then when I put them under the 500w light 25% strength about 50in from plants and they were getting only about 195umol in that tent but it was stressing most the plants. I assume a larger light has more side lighting hitting the plants. I think when useing larger lights it's good to measure umols from the top but also coming from the sides. I think durring seedling stage they only need about 50% the umols coming from the side the plants as the top is receiving. When I put the plants back in the small tent about the same umols as they were getting b4 the switch and they were still a little stressed. So for a few days I put the small light at the top the tent giving them 100umols for a few hrs then 130umols the rest the day.

8/3 Went over to treat the 10th planet that needed water with plant doctor around 10:30. I was in the garden at 6 but didn't have much time. That plant seems to be curled up or "droopy". It DID need water. I defoliated a few sep leaves off it but I didn't see any today. I guess I don't ever really see the leaves "up" or praying like I do with the rest of tge plants. It's starting to flower like the rest though. Today is the day everything is supposed to get its second or third plant doctor dose but I decided to wait until they need the water. I don't think 24hrs will mean much. I've been staying on top of defoliation but I'm seeing some pillar damage. I'd like to spray bt but what my buddy said about spraying with septoria is still in my head. Maybe I can use citric acid. That way it won't "wash away" spores it will just eat them. At least I think. And I hope lol. Birds get most of the pillars but I hand pick some too. I need to pick up nutes. Wondering if I should just get grow big again. I don't use much but plants are switching to flower and leaves are fading. I have big bloom and kool bloom bit neither have nitrogen. I still need some sort of nitrogen. Especially since that could be a deficiency. Not sure if it's the transition or a condition with the sep. I see some interior small leaves bleeding out and some dying. I'm wondering if what I thought was earwig damage years prior was really a combo of sep and they just ate the evidence. I'm super grateful though. I've got some resilient girls and they're doing well. The special kush in flower is gorgeous as well. Looks like I'll have an early plant. Short flowering time on this strain. Smells pungent.

So, first of all, I want to say that I´ll be doing the diaries in a weekly updates way, instead of day by day, not only because it is less heavy on me, but I think it´s a better and more attractive reading. So, tell me if you prefer day by day or weekly updates please! Thanks! So, this week was pretty good, thricomes are looking pretty close to harvest. About 90% cloudy, with a little amber and clear. Watered with regular water and didn´t feed her. Flushed it with regular water on day 74, looked like it had still lots of nutes/salts buildup. And about flushing: I saw a really good study (I can link if it´s of interest for someone) showing that flushing isn´t really required, specially if you´re doing organic grows. It was really well explained and had solid arguments and comparisons, even tho, I flushed her in order to see if it really makes a difference. On day 76 when i first opened the tent in the day, she was all the way to the floor, almost hitting 2 tiny girls on the tent. Since she doesn´t had any strenght to support herself, I used some ropes to mantain her up. In resume: The week´s been really nice, she´s beautiful as hell with some purples and I´ve learnt some really good stuff as well.

Week 5: Preflower Transition & Canopy Management Update: June 21, 2025 (Day 38) The plants have officially entered preflower although it doesn't look very spectacular. But this will surely change my guys. Significant LST efforts continue to maintain an even canopy - all shoots are systematically positioned around the pots and secured with electrical wire for optimal light exposure. Strain Progress: Forbidden Runtz Maintains its dominant position as the largest plant. Shows the most advanced preflower development with numerous white pistils emerging. Its vigorous growth pattern suggests exceptional genetic expression compared to the others. Green Crack Remains the smallest plant with delayed preflower signs. However, its recent growth acceleration is notable. Given its later transition into preflower, it may still achieve substantial size. The anticipated mango aroma from previous grows remains a key point of interest. Bruce Banner Exhibiting impressive vertical stretch. All new growth has been immediately trained horizontally to promote additional cola development. Its reputation for large size keeps expectations high regarding its potential to rival Forbidden Runtz. Environmental Management: - Greenhouse temperatures monitored daily - Plants moved outside when temperatures exceed 30°C - Continued pest vigilance in enclosed environment Next Phase Focus: 1. Maintain LST adjustments as stems thicken 2. Monitor early bud development Thanks for checking in guys and hope you enjoy my dairy. Smoking_Joe_Frazier

MrHide Seeds Test BESTAVA Quantum Board 2000W (SAMSUNG LM301B LED) Muy feliz ! Cero plagas con la tierra diatomea , se las tiro por todo lado. Se me dañó el deshumidificador y el porcentaje está en 80%, pero aún están en vegetación entonces no estoy preocupado. Crecen super fuertes, sin deficiencias aparentes o daños. Las Kritical Red ya están empezando a dar signos de floración, vamos a dejarlas que den sus primeros pasos solas y en unos días le empezamos a dar de comer y estimular nuevamente. Esta semana les he ido haciendo defoliación fuerte y ha dado resultados. Los brotes inferiores han subido bastante y se les ve mejor estructura. Esperemos den buenas flores. Buenos Humos para todos los cultivadores ! ¡cerotes, gueyes, culiados, pizados, boludos, jodidos, maes, patas, parces!

AMAZING WEEK! The environment is reading for flowering. Lighting, feeding, watering, air temp and CO2 are all stable and should give my plants a stress free life. Humidity is still high, so I'll need to come up with a plan for dealing with that ASAP. I've introduced CO2 into the grow with my brand new AirBomz unit. It uses a light sensor that releases CO2 when the lights turn on, and then uses a timer to release every 2hrs until the light switch off. I doubt I'll reach the 1200PPM stated by the manufacturer, mainly because I'm running an extraction, but I figure some is better than none. Cool controller also included. After doing some reading I can see there's two things that I need to look out for: A) Switching off the extraction so it doesn't suck away the precious CO2 before the plants have had a chance to absorb it B) Making sure the room doesn't get too hot whilst the extraction is off, causing heat stress My solution is: A) Switch off extraction for 15mins at the AirBomz 2hr interval B) Use the Temp Controller the switch off the circulation fan when temp exceeds 27C C) Controller then switches on the active intake when temp exceeds 28C D) Temp is held at 29C whilst the extraction is off D) Extraction turns back on after 15 mins, temp drops below 27C E) Temp controller switches off active intake... F) ...And switches on the circulation fan G) Repeats every 2hrs NEXT WEEK: Work out how much the girls are drinking! I'll know when I change the reservoir.
