Rollitup

if I were to pick out of the 3 I would buy the EZ8. efficiency at 2.7umol/J and a 1000W. So you can be running them a little dimmed and be more efficient. The $/ watt kills the other two light. Use the $3-400 you save vs spec-X and buy UV/IR bars seperate. I wud try a cycle with just EZ8 and then add UV and IR next.

any 3 of those would spank a 1000W single end HPS light though.

Lots of people grow quality buds without UV and IR. Think of UV and IR as tools to help you out. IR/UV can help speed up ripening, can influence stretch. If you use Ir only taller plants. UV only shorter. Use both and balance them out etc etc. And there's more benefits to both. But 420 character limit for me stressed. Lol
