ViparSpectra XS 1000 (x2) vs. HLG 100 RSpec (x2)Thoughts on VS XS 1000 (x2) vs. me buying HLG 100 RSpec (x2)? They'd go to either side of my HLG 225 in a tent that's 2.75' deep and 5' wide to 'fill the wings' more evenly. Thoughts on build, safety, quality & heat? HLG 100RSpec:0 / XS1000: (on sale this weekend)

Trying to get setup right I know I prob need to get a nicer light and ditch all the crap lights but for now I have what I have. Perhaps after some success I may be able to get a new light to replace all of them. But how far should it be? 2 feet above rockwool cube? And what watts per plant
