I purchased a Diamond XML 150 used so it doesn’t come with an instruction manual.
I don’t know the best way to set the light adjustment? There are 2 knobs to set it. One of them turns on a white light & the other one seems colored like blue to me.
I have seedlings right now so I don’t know how best to adjust the light for seedlings, distance from the light, hours of light, etc. They are “auto flowers.”
