I’ve been running a 100 watt full spectrum at full power about 22 inches above plant, but today I added reflective mylar surrounding the area and lowered the light to 18 inches and set it at 80% but will go back to 100% in a day or two.
Very nice. I just started 2 sour diesel that have emerged from the soil and one still working on popping tap root out of shell. Hopefully they will do as good as other strains have.
