Well I have had my mothers under the "12-1" schedule for two weeks now and they are not starting to flower so this part of it actually works. They seem to be growing at the same rate. I have had my next round of babies going under 12-1 for over a week and they are looking great. I am shocked that nobody else is interested in saving 5 hrs of electricity a day during veg! I will be testing out the end of this 12-1 cycle during flower, but have no doubt that end will work. People already reduce their lights during the end, so this is not going to be a problem. Guess I will have to journal one of my grows to get people on board since everyone seems to be more interested in threads about how to make crack cocaine
Your ass is play doh and I am the fun factory
I've heard about this light schedule as well. I'm also lead to believe the benefits far exceed the savings on electricity.

your math on the electricity is off. it would be 150kwh i have a calculator for that stuff. so at $0.10/KWH you are looking at $15 a day.
and i've had plants go into flower under 18/6 so idk about 12-1 i can see the flowering times with going to 11/13 and decreasing because trike production and maturing happens at night anyway. i leave my plants in darkness for 72hours before harvest and they just pump resin during that time. i just think the 12 on 5 off 1 on 5 off that 1 on would stress out the plants thats not natural at all
5.5 hours off/1 hour on/5.5 hours off. Hmmmm....Just my own opinion, but this violates one of the most inviolate of all rules of indoor growing. Interrupting the dark period. Whether or not you're in veg or flower. You can flick the lights off and on all "Day" during the light period, but the dark cannot be interrupted. It's not the length of the day that triggers flowering, but the uninterrupted length of the dark period. You're gonna be lucky if they don't hermie.

I know this is about keeping them in the veg state, but this is gonna HAVE to screw with the plants hormonal responses to light. Even in the veg state I would think.
My power co. charges .09 per K/H, so this method would save me less than .50 per light. I didn't switch to 1K lights because I was worried about my power bill. I wanna give the girls what they want/need.

No, I haven't tried anything less than 12 hours of light per day, because I want to grow the best plants that I can indoors.
I know it was written almost 30 years ago, and the research cited is older than that, I'm still going with Rob Clarke's marijuana Botany. I give my flowering plants 13 hours of light and 11 hours of darkness.
Rob Clarke says that less than 12 hours of light per day will result in less THC produced. So here it is, like I've copied in threads on this board for years:

Therefore, I give my plants as much light as I can give them, while keeping them in flowering.
im pretty sure that resin production happens ONLY during the dark period so i think you have it backwards. more light time doesnt make for resin/THC more dark time does. this is why a lot of growers will put their plants into 72-48 hours of darkness right before harvest to get more resin buildup before cutting them down.
