If you're scrogin' to keep the plants from falling all over the place (aka gangster lean) ....Just get some agricultural trellising and some bamboo poles....no?
I think you would be better off with a mix of half ffof and half happy frog with added ewc....I would hate for the ffof to be too hot and burn the clones...
Maths.........ffof bags are 1.5 cf or about 11 gallons happy frog is 2 cf or about 14 gallons....about 200 gallons in a yard..
most/some...
As much ewc as you want to pay for...it wont burn plants...I used cubic foot per quarter yard of soil...also eb stone is shitty ewc... Seeds or clones?
I have never grown autos .....That was just something I read....I have some dinafem cheese autos...but I don't have a lot of interest in them..
I don't think it matters when you transplant them now...
When I transplant...I use my fingers to poke holes in the dirt to loosen it up a bit...I don't really know why...Just always done it like that...
You shouldn't transplant autos....start them in the pot you will end with....lets say they have 30 days of veg...if you transplant you will lose 3-7...
When I first saw your pics...I was like best hidden guerrilla grow ever....
patio plus has loads of sticks and twigs in it...splinters suck...but that said...it does grow well...
