I am just finishing my first indoor grow with 3 autos. I grew them for about 12 weeks at 19/5. They weren’t close to finished, so at week 13 I decided to dial back the hours of light in an effort to manipulate them to finish.
Well I screwed up and added hours of light instead of reducing.….my timer is confusing to a simple guy like me.
During this time I was just finding out and learning about VPD. So my temps and rh were moving around a lot and I was trying to dial in.
I was always told that autos didn’t follow the normal cues and weren’t susceptible to darkness interruption problems. So it wouldn’t be uncommon for me to open my grow closet door several times during the dark phase to check my VPD. I thought nothing of it.
Weeks passed and the plants weren’t finishing and I began to spot a few very small new oval leaves with smooth edges. It looked like textbook re-vegging to me.
I’ve since corrected my light schedule and reduced to 11/13. They don’t appear to be growing any new oval leaves and are finally finishing up…..but it took 18 weeks to get here and will be another week or so before all 3 are hanging…..oh and they started flowering week 4 and had little round heads by week 5.5. So it’s been a long flowering run.
I’m still told by some that autos don’t re-veg…….I think they do.
