Bro I am an HID grower with 1 toe into the led world. Optimistic but not 100% impressed yet myself. That said I love all growing and methods and feel there is no wrong way as long as the grower is having a good time.
Actually, failing is part of the fun of learning and having a bad ass hobby.
It really doesn't matter much what media one uses but they are going to be feeding. That is what I meant about not making it to the end.
Anyone thinking they are doing a charged or "living no till" with no liquid feeds isn't going to be very excited about their results
