Well I've been looking around and I haven't been able to find any T5s.. So in the end I'm just going to go with a 400W MH for the vegetative cycle and a 400W HPS for the flowering cycle. BUT... While looking through all these growing sites for T5s I ran into a system that interests me quite a bit because I won't have to deal with soil and they apparently will grow better: it's the GRO-TANK GT 604 NFT hydroponic system, and it seems to me that one of those for the vegetative cycle and one for the flowering cycle would be the perfect size for 5 plants in a row, it would make less mess, take less work and give a better yield. So any opinions?
