2 Glue Sniffer and 2 Purple Cream in Aircube system 4x4, Jacks 321, MH fc8000 with ir, uva, and red supplement bars. Second pic is the GS getting early frost and 3rd is the PC starting to stack.
Leave the door unzipped at the bottom if no vents. I run my tents this way even with vents...but my lung room is fairly dark so not much light bleeding in at lights off. With autos it wouldn't matter and I haven't had a problem with photos either.
With coco you need to fertigate daily(at least)...that's food and water. Since coco is inert you have to supply everything. It's almost impossible to overwater...that's the big difference in how they're treated.
Coco will out preform soil with all other things equal....in growth rate and yield.
I encourage you to research DLI.
Also there are ratios of uv, ir and far red that will benefit the plants instead of cooking them.
All your plants look stressed now compared to before you went berserk with adding lights. I recommend a cheap par meter or at the very least the "photone" app for...
Diatomaceous earth, sand, and lots of other things on the top of the soil will help control or eliminate them. Do a search for knats here for a few threads on controlling them.
Good luck!
I try to keep it to a minimum with autos but modern genetics along with hydro or coco can make for some huge plants that will absolutely require some defoliation. As long as the plants healthy it's fine to defoliate.....just don't go crazy. I like to take a few leaves/day to keep stress to a...
I was referring to the wicks getting clogged but I guess stuck valves and stuff are where the other complaints come from with organics in hydro. Also there are problems with sediment build up or just stuff dropping out of solution with organics. As I said it can be made to work but you are open...
I should have said it's "easier" to get atypical growth with autos in hydro. I've found my best yield with autos comes by not topping and instead using some lst or just tucking a leaf or 2.
Organics not so well....they tend to clog. Not saying it can't be done but it adds another layer of possible issues.
I use salts with good results with wicks.
Are you planning to feed through them...or just water?
If water only it's easy...just set them on the bases after first set of true leaves and watch them grow.
Feeding through them works great but can get tricky with buildup like @conor c said.
