Sweeeeeeeeeeeeet!
I'm starting to have some results now, too. My 5 little Reclining Buddhas are looking happier after a slow start. I think it was the cool temps and drafts, being in a corner of the house during Canadian winter. A tent would fix that but I've never used one, and seem to have made it through the worst now.
And yeah I find 20/4 is better than 24/0 for a few reasons and that is one of them. Another is the plants have an easier time adjusting to 12/12 once you flip. I think they like having a few hours of "night" so they get a sense of the passage of time. Sure, cannabis sometimes grows in parts of the world that get 24 hours of light, and many strains can handle it, but doesn't mean they necessarily like it, or that it's natural for them. A few hours of darkness doesn't cut into their growing very much, and seems to have benefits. I imagine even a couple hours of dark would be an improvement in a lot of cases.
Glad you are feeling greener and happier! On we grow!
