My clones show first sign of Bud at six days into Bud Room...after the switch to 12/12...
The one week [6 days] I call my conversion week...I note it, but do not count it as bud time...
I start counting then...after I see buds forming...
If you grow outside, "Mother Nature" does your light/time switch...
If you grow outside, you start counting when you see buds, don't you?
Why would inside be different?
