flipping to flower

my times are not what i want for flowering if i goto 12/12, 24hrs after last 18/6. can i leave the light off 36 hours or so to get my schedule i want?

Not sure I follow this right, but if you just set your timer to the 12/12 sched you want, you'll b fine. If you go over 18hrs on to get the flip. It's ok, if you go more than 6 off, that's ok too. Your over thinking it.

Just put your timer where you want your schedule and go for it to make the switch, one time isn't going to do much to your girl. Personally your next grow just try and keep any dark period during your veg to match your flower time, just one less thing to worry about in the future. Good Luck and Happy growing

I just went 18 MH then straight 12 HPS so 30hrs of light. I have buds forming on all plants and theyve more than double in height 10 day since flip.

yea decide to go 24 on then do my 24 off will put me with lights on @ 10pm which is what i want, save money and heat.
