I think it does matter.......use it in soil and not coco. I have yet to see a successful grow using this method........everyone has problems. I haven't actually watched his videos but another member here on GC says that his plants look burnt and crappy looking........I don't think he'd say that if it weren't true.
Yeah im with mick mate. Mr canuks methods are wrong on so many levels it would take me about 90 minutes to explain them all. Ive never seen anyone manage a successful grow followi him and I'm talking like 150-200 people over the 5 years I've been on the forums. Youd be aswell just soaking a pineapple in vodka then chucking a seed in it. Just as much chance of success.
