5 out of 16 seeds sprouted View Thread Reply Hide Archie Blythewill - Tue, 17 Apr 2018 14:33:51 EST oo8zzN+e No.145905 File: 1523990031618.png -(123510B / 120.62KB, 500x479) Thumbnail displayed, click image for full size. I planted 16 seeds about a week ago from a reliable breeder.In a few days, 3 popped. In a few more days, 2 more popped. Now it's been nothing for a few days. Am I being too impatient, my time perspective off, or should I lightly unbury and see if they popped a tap root or will that do more damage than good and just let them sit and if they make it they make it but if they aren't gonna make it nothing I do will help? 17 posts and 5 images omitted.

I have a gorilla glue autoflower here with (probably) a wide range of problems but am not sure how to proceed.It's at 16 and a half weeks from seed, however while LSTing about 2 weeks into flower I accidentally snapped the head off. This led to it growing really wide and fat.During most of the summer the temp was sitting at 32c, obviously too high but nothing else I could do. I also found some bugs on it during the summer, however they appear to not be there any more as far as I can see. The other plants in the tent were not affected by any of these problems and are doing just fine.The actual problem I have is although the buds are fat, the pistils don't seem to be turning orange. Some are, but it seems to be stalling / going very slow.Leaves were yellowing as if it were finishing, but some have dried up with some dark spots on them. Just wondering if it will actually finish or if I should just call it and cut it down. The buds are sufficiently fat, it just doesn't look fully finished.

I took my time and topped it a few times so that I would get 16 symmetrical main tops which I made fill the entire space with low stress training by tying down the branches with soft rubber coated wire plant ties and duct tape. During flowering the colas got super big, longer and thicker than my forearm. I noticed whatever was munching on my roots right when I was debating changing it to flower at the end of a long veg, that settled the debate and I started to flower. It worked quite well but eventually near the end the little critters had basically eaten the entire root structure so it didn't finish quite right I think. Still it was an amazing flavor and high. Growing in perlite is a good option if you can keep it sterile I think although deep water culture is safer imo because few critters can survive being fully immersed in water. You can add worm castings to a deep water culture to get beneficial bacteria and fungi that help protect the root zone. Change your water every couple of weeks and each time mix up an extra amount of nutrient solution and clean your air stone or whatever you're using to oxygenate the root zone. Save some of your extra nutrient solution to add in later when the plant drinks it. Add fresh worm castings only to the root chamber not the extra nutrients because the beneficial microbes won't survive in water without it being oxygenated. My best weed came from when I did this. I had a small rockwool starter cube that I placed the germinated seed in, then I put that in a small net pot filled with perlite with gravel on top. This small amount of perlite was pretty good I think because the perlite sucked up moisture from the reservoir beneath it and wicked up moisture to the rockwool but the rockwool was above the water so it had pretty good oxygenation. You just need to make sure the bottom of the net pot is submerged in the water. Just run straight water until the second set of true leaves form then add 1/8th of the nute bottle's mixing formula and slowly titrate up to maximum strength over the course of a month. I did it in a 5 gallon bucket with a couple of air stones in the bottom and a couple of aquarium air pumps. Root oxygen levels are important which means you need to consider two things, water temperature and water aeration. The bubble stones will aerate the root chamber and eventually your roots will grow down through the damp perlite and hit the water itself at which point you get a real boom in growth. The roots form clusters that plunge down into the water chamber and if the plant is given adequate light it will respond with much faster growth than any other method I'm aware of. One of the tips I've found that is most important but is easily overlooked is that the closer you can get your lights to your plants, the more intense the radiation is when it hits the plant and the more energy it transfers. The plant itself can tolerate high temperatures in the 90's or even above for some strains and will actually grow the fastest and most vigorously in high temperatures, right up to the point that the enzymes begin to degrade from high temps at which point you'll see a big drop off in growth. This means you don't want your lights to be so close that they burn your plants, but if you have adequate airflow and light cooling, you can benefit by increasing the efficiency of the watts you're paying the electricity company for by moving the lights closer to the plants. I think that many lower wattage, cooler running LEDs or Flourescent bulbs spread out that can cover a large area and be placed close to the canopy is a much better choice than a single high wattage, high temp light placed above the same area at a farther distance. The coverage is better and the intensity per watt is better with more lights at a lower wattage each spread out and put closer. Pay attention to the spectrum of the bulbs you're going to get though and look at cannabis' active use spectrum that will tell you what spectrum you should be targeting. The root chamber must be kept cooler than the plant itself though. Some sort of refrigeration is optimal, but insulation and shielding from the light above can be adequate. >> Walter Simmlehood - Wed, 08 Aug 2018 18:45:19 EST ef1tcmWF No.146231 Reply >>146230BTW I have used both CFLs and LEDs and I recommend them both. If you want to do a cheap CFL setup you can get a couple of power strips and some adapters with a slot to screw in a light bulb on one end and a plug on the other that you can plug into an outlet to power a lightbulb. Turn the power strips back to back so that the power outlets are facing outwards, then plug in three light bulbs on each side. You can zip tie or tape the power strips together. This makes a ghetto light fixture that is cheap and can work with CFLs. Use standard size 20-30 watt (actual, not equivalent) bulbs in the correct spectrum that come in the standard size. You can put a reflector of some sort of white or shiny material like mylar above the lights so that the light emitted by the cfls that goes up is redirected to the plants below. CFLs emit the most light from the sides of the bulbs, not the tops so this fixture is optimal as all 6 bulbs are placed with the tops pointing out to the sides and the sides of the light pointing up and down. Two of these will cover about one to one-and-a-half square meters. You can also choose to put pairs of 2 on each side rather than 3 or split up the strips so they're not in pairs. The less bulbs there are clustered together, the less heat there will be and the closer you can get them to the plant canopy which means the more intense the light the plants are exposed to gets. Led light fixtures are neat and probably easier to work with and have even better cooling and efficiency than florescents. You can also get really into building custom LED setups if you're into electronics but I've never messed with any of that. Your plant can take in as much light as you can give it in a deep water culture because there's an optimal amount of water. The plant will just respirate away like crazy and build and build and grow and grow. You can be aggressive with your nutrient feeding as long as you are religious about keeping your PH optimal. This is where most people fuck up. if your ph is fluctuating each time you change your reservoir or when you add in more water in-between changes, your plant will be stressed and/or nutrients will be locked out and plant growth will suffer as a result. It has to be kept precise and never change but if you do this it's surprisingly easy and gives insane growth and yields. >> Charlotte Blarrywill - Mon, 20 Aug 2018 21:27:06 EST B0kZyQRI No.146277 Reply >>146231Thats a pretty great guide to growing indoor hydro you packed into those two posts. Good to know your plants turned out nice too, on the topic of pushing maximum light, I'd love to see someone take hyrdoponic growing outdoor and really push things under sunlight, possibly using reflectors of some sort to add to the intensity of the light.

Any ideas what causes this? It's almost exclusively the lower leaves doing this and some lowest small flowering branches nodding off or browning and dying but they are like 3 feet from the lights anyway.The monsters are about 5 feet tall so obviously light penetration in the lowest levels is slim.Been some 2 weeks in flower counting from first pistils.Hydroponic, using bloom:micro in 2:1 ratio, EC around 1.3-1.5, but it keeps rising so I'm going down to 1 slowly. Doesn't seem to be nute burn though.Using liquid silicon occasionally at 1 ml/litre. Sometimes adding hydrogen peroxide 1 ml/litre tops. Using top max 2-4 ml/l.PH fluctuates approximately between 5.7-6.5 depending on adding new water etc.Temps may be a little high but not super overkill. There is colder intake blowing under the canopy at almost ground level. Not sure if too cold. 2 posts and 1 images omitted.

LED burn or not View Thread Reply Hide Alice Crennerpock - Thu, 26 Jul 2018 12:51:31 EST 5R5q7BKE No.146185 File: 1532623891347.jpg -(162990B / 159.17KB, 900x1200) Thumbnail displayed, click image for full size. I think I might have killed my plant with too much LED.Had a plant growing under 7 5.5W bulbs and one 50W (All actual draw) at ~40cm height (15 inch)It was doing fine, not great but good enough.Then I got two more 50W leds and placed them on at the same heigh.At which poing my plant basically stoped growing completly and the leaves started slowly turning yellow. I though it was because I overwatered it twice in a row(got almost 50% run off both times) and that's what caused leaves to yellow and stunt growth.Then I planted new seed. it sprouted grew first two real leafs then they raised almost vertically and then they slowly started getting yellow too, like on the previous plant and it didnt grew one bit for about 5 days now. I did place it at about 60cm (23inch) heigh on the 2nd day or so but it didn't helpThe space is 60cm by 60cm so about 0.36 m2 (3.87 square feet), medium is coco.So, is it LED burn after all? Or some other combination of things?If it's LED should I take out some LED's or put them higher?pic is not mine but looks similarly, although mine were more yellow than brown. 4 posts omitted.

LED lumens per cubic feet?

I have a tent that is 41 cubic feet. I have 29k lumens from my LED lights. Will this be optimal for that tent space? I don't care about heat, just whether that lumens per cubic foot is good with LEDs. Does anybody have an idea or does it entirely depend on the LED spectrum? 2 posts omitted.

Second time grower here. I previously grew one plant and it turned out okay. I decided to try again. Bought two clones from a dispensary and transplanted them into my grow tent 3 weeks ago. Originally, it looks very healthy; in fact my other plant was the one that was starting to wilt. A week later, the tables had turned and my previously wilting plant exploded in growth and looks really good now. However, one of my plant's stems aren't growing longer, it's only growing fan leaves. Anyone have an idea why this is happening? I couldn't find much information about it.A little bit of info regarding my set up: 6x3x3 ft grow tent, 125W lamp, 2 inline fans with proper ventilation, 2 more small circular fans inside to circulate airflow. Both plants are using the same medium + nutrients. pH level is 6.8, fairly normal. >> Hamilton Blythespear - Fri, 27 Jul 2018 14:36:41 EST F5Zo2jXE No.146190 Reply 1532716601545.jpg -(274310B / 267.88KB, 1000x750) Thumbnail displayed, click image for full size.
