I'm using the really finly shredded up coco, can't remember the name for it but it's really nice stuff.
As yeah I'm using a two part fert (comes in A and B) as well as liquid n and oxygen.
Using the same stuff now bro, well at least the CoCo A+B. I also got a gang of other products from Canna. You ever used them? Got the babies looking nice at 3 weeks though. Be sure to post the names of the nutes, Id like to check them out.
I'm using Vitalink, picked it up in the growshop and it seems to be doing a great job, I want to look into some of those Canna products, they look sweet.
Your plants are looking great man, mine started off really slow but then exploded!
