I placed 4 of the XS-1500 in my tent.
Seems I prefer several smaller lights so that I can move and space them as needed.
Will be interested to watch your progress.
Yes, they are together, but with switches for which to use, the IR or UVA.
I have started into flower, so I am thinking at about 21 minutes before lights out, run uva 7 minutes on, 7 minutes off, 7 minutes on, and then all lights out.
2 separate timers (which I have)
I did try smaller uva lights...
