I recently bought Arcadia D3 T-5 54 Watt 12% UVB bulbs. I was wondering how many watts per square foot I should be running of UVB? I currently have a 2x4 tent. Thanks in advance for any advice.

Avoid UV except for the last 2 weeks before harvest should you feel that the trics would need a blast, cannabis don't need it, and unless you have great private health ins.. you either

Thanks for the reply brother, I am currently in the last two weeks. How many watts and for how many hours do you think?
