Growing In Coco  

go for 100% coco in air pots mate, no need for powerlite. 

15l will be plenty, four plants in a pot that size, will fill you tent, trust me, ive been there, you dont want more than four, in 15L air pots.

Strart of in 0.5L small plastic normal pots, then go tino 5l airpots for veg. After a few weeks, transplant into 15l airpots, give them a week to recover and grow more root, then flip them. 

powerlite lol, fucking typo fixing machine dont know shit!

Take your word for it, been there with the grow under stairs. Do not want a repeat of that! Hear you loud and clear Haha

Shame though as did try find 15 but couldnt with my searches only find 7 and 10, 19.5, 40. Will have look into it more, have a bit of time till buy that

Perlite?

If there a more modern quality brand I can go to for coco let me know 

you said 20% coco, i thought you meant perlite. For a coco grow mate you use 100% coco, you can mix it with soil, but that makes it a soil grow. The nuits you have will be fine for coco too

I did actually meant 10-20% washing the coco, loose bits tend to come out, so consider this when buying for preparation? 

I was going buy a bag of perlite aswell for the coco, should I not?

I'm all out soil now so will go away from that to try coco didnt intend to mix the two, only thought I had was clay pebbles at bottom?

Air pots and coco is all you need man, no need to add anything else get two 50l bags of coco, thatll be plenty:

Coco Link

4 x 15L Airpots

There you go mate

Also will try remember to run it all through the site before i buy

i still gotta find a 4x 5l though, 2l bit to small?

Its already linked up for you mate
Just got for fabric pots for veg, much easier to find

In my opinion 5l is too big go for a 3l first, pot should grow with plant.

True, buts its not easy to find 3l air pots. The roots grow quick in coco too, it'll fill out fast with some rhizotonic, otherwise your transplanting three times in the grow, 3- 15L seems too much of a jump too, so you would have to do another transplant in between? How do you do yours mate?

With another transplant.  I am just setting up a coco grow so I got my boss helping me. Sometime when you go to big your roots will spread thin and forget about getting thick. But you can only do what your able to get I’m now lucky to have a choice of everything. I also have pre soaked my coco in super b but don’t use rhizotonic. What are the benefits to rhizo or is it just organic sea shit with vitamins b added? I haven’t cloned yet but that’s where I’m heading. 

Perhaps I could go for the 3l, 7l and 15l? Seems good jumps. I've already paid arm and leg why stop now.
