Rollitup

All your tent should need is one CLU058 @ 120w for 30 watts per square foot. The walls of the tent will reflect back plenty of light. My last few runs have been as low as 20 watts per square foot with 5' tall plants.

Thanks for the input just one clu058 right in the center? Also I was thinking 4000k to prevent stretch but what Cri should I use? Also which driver would you reccomend? And should I use a lens to spread the light? Sorry for so many questions but the amount of source material on leds is immense and you have lots of practical experience with a whole range of leds. Thanks again I appreciate it.

Are you anywhere near the Bay Area (CA). I sell lights through a store in Concord.
HLG120H-C1050B with a CLU058 3618 and a good heat sink.

No sorry no where near California, would the hlg185 work with a dimmer? In case I ever decide to step up to a bigger tent?
