I can't speak to taxes and the EU. I followed PGR and I can't remember what he was having trouble with but am not sure if he followed directions, gave it a real chance and also think he said he would try again. Also, that is 1 instance out of many. I'll even give you another, Sweet Sue, stopped using it because Hempy was better for her, she still loves the kit. Again, you're gonna do what works for you. Just giving you a heads up, this is the best and most affordable growing system out there. Give it some thought bud! PGR, not trying to put you down bud, I know you can succeed with the kit if you give it a chance!
