Hello all,

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.
