Pre Flower Temps and Humidity

So actually this grow light right? https://amzn.to/2JQRfsO Their PAR chart shows 565 dead-center at 18" so if you reduce that a little more then you should get within the 600-900 PPFD range which is ideal for flowering w/o CO2 supplementation. Unfortunately since they only show 1 PAR chart, the light distance is a guessing game. I tried to find a PAR test video on YouTube for this light but couldn't find one. Maybe move it down to 17 inches away and see how the plant likes it? Up to you.

@drowser You either need a PAR meter or most people just look at the grow light listing and go by the PAR chart shown there. I like to run 600-900 PFD when in flowering.

@drowser They look like they are starting to develop as they should. The plant does appear pretty small though. Can't remember if you've talked about which grow light you're using and light distance in another thread on here or not but 600-900 PPFD is what I like to give my plants when in flowering... More towards 600 early flowing then increasing as the plant gets into mid and late flowering.

2-viparspectra v300t I had it about 30 inches above the canopy , I lowered it to 24 inches.

@drowser This one right? https://amzn.to/3l7D68d Looks like at 24" you're getting 237 PPFD in the dead center.

@drowser She looks healthy from what I can see. What strain is it? Is it an auto? What day is it on?
