This would be a scheduled flushing. I like to do it every 2-3 weeks, just on general principle.

I'm having huge heat problems. The ambient room temp is 80F, and the temp at canopy level is 84-86F. I have to open the window in my room and freeze myself to death to keep my closet sufficiently cool at canopy level. I read in HT Mag that I don't need as much light as I'm using. So I thought maybe it would be okay to raise it to help with canopy temps. I mean, my light puts out 50 thousand+ lumens. For 4 plants. I could probably raise it and still get sufficient light. I'm just trying to avoid them stretching.
