I’m looking for some lighting advice

Mugwort · Aug 9, 2021

I recently added a second ViparSpectra xs-2000 to my 4’x4’ tent. I have them centered 22”over a SCROGed canopy which takes up about 80% of the net. Manual suggests 18-22” at 100% brightness but I assume that doesn’t take into consideration the overlap of two lights. Along with creating a heat problem I am wondering if I am bombarding my girls with too many photons at 22” and 100%. I am using ProCO2 buckets but only for the first 3 hours in the morning can I keep my tent sealed up with the lights on owing to heat build up. Once tent temp reaches 82° I opened it up but I’ll deal with that later, right now looking for a little advice from somebody that knows their lighting.

You could lower both lights- but only use one at a time with some overlap. light 1 turns on at 12:00 off at 2:00 on at 4:00 off at 6:00 on at 800 off at 10:00
light 2 on at 1:50 off at 4:10, on at 5:50 off at 8:10.....You can get the same DLI with less power and heat. Also kinda mimics nature like sunlight is broken up with clouds.

Or lower the lights and turn the power down. but my first idea sounds way cooler.

Why would somebody do that?

Co2 plus 84F is not a problem. You want to get that down yo 80F for the last 3 weeks. But it's in the ideal zone at 82 during rapid growth.
