Yeah I grow in 'ton. My cuts rooted for about 23 days and I put them into 12/12 under a 1k HPS Last Monday and Tuesday (I put a few in to make sure they wouldn't die on me because the light was too close, the cuttings not rooted enough, etc.) and they went crazy on me. The tall ones are already 9 or 10 inches tall. They grew a couple inches by the second day.
Vegging them at all with my setup would've been a giant pain in the ass.
I call veg time, waste of time. For SOG'S that is.
