Greengenes707 my biggest question/concern is how far to keep my cxb3590s from the canopy. I see some quantum Flux meters In the 350$ range (ouch).
I have 8 cobs on a 12" x 36" heatsink, so they are much closer together than some others setups.
Do you recommend a budget meter?
And I hear up to...
Realstyles and ChurchHaze, do you think plants would benefit by adding deep blue T5s, specifically (ATI True Actinic and Coral plus) together with the Cree CXB3590's?
