That will slow growth, you want low 80's under led, they don't have IR to raise leaf temps above air temp like HPS etc.temps are around 72f currently
My fc4800 does include IR and UVThat will slow growth, you want low 80's under led, they don't have IR to raise leaf temps above air temp like HPS etc.
So with my current temp at 72F and RH at 55% I appear to be within check for VPD although I could lower is 5% to improve?leaf temps
The Ultimate Vapor Pressure Deficit (VPD) Guide
"Why devote an entire guide to VPD?" you might ask. The answer is that the vapor pressure deficit (VPD) is extremely important for growing plants. VPD helps you identify the correct range of temperature and humidity to aim for in your grow space. With VPD you can achieve the best results while...pulsegrow.com
I would crank it to 100% and raise a bit moreHere is a pic of the light in question. I did end up raising it to 24" and turned it to 75% on dimmer. As this is a commercially used light was curious how the would have it set in a legit grow
Yes, but an insignificant amount of IR compared to hid, not enough to raise leaf temp reletive to air temp. They add a few IR diodes so they can advertize IR. Check the air temp in the chart Osbuds posted.My fc4800 does include IR and UV
