I know this threads probably dead, here's what i found, growing on an 11/13 will RIPEN your girls very quickly note i said ripen.
imo the problem lies in that by cutting down the hours of light you are losing some of the most productive days of growth as your plants will ripen Before that time arrives, its not a case of just adding up the odd hours and deducting the days, when you look at natural daylight hours we don't get to 12/12 until mid september so possibly by shortening the light cycle the plant is fooled into thinking its nearly november and proceeds to ripen before the buds have finished swelling...these are my own observations and i would agree that yield is lower...i wouldn't personally mess with the standard 12/12 if you want colour let the temps drop in late bloom.
Um, with all due respect. Your quite wrong sir. I run long, on purpose. I run 11/13 and have no effective
early ripening - period!
My yields are not lowered at that time. In fact I get quite high yields!
In reality sir, 12/12 is very unnatural! It can be stressy to more strains then you think to simply run 12/12.
You need to do more research.....Been doing mine for decades...
This is weird... 6 weeks ago I had a plant that had been in flower for 2 weeks or so. My tent got over crowded so I called a friend who said he would put it outdoors.
Since we are getting 15 hours of light right now I told him it would definitely go back into veg and finish in the fall.
Last weekend I went to his house and the plant had fully flowered and is now completely finished under 14-15 hours of light.
Not really! Some verieties - Sativa's mostly. Revert when placed under lighting times over 13 or near it. Indica verieties will continue to bloom even under long light times. Ed said something like this years ago. I agree, as I put out blooming plants and let them run outdoors. I like what the plant and the lighting do to the bud structure...Plants are put out after being flipped but, before budset, in my case.
Cutting down of the growth period (light) could be avoided by messing with the 12/12 by adding to the light period without changing the dark period. So that you now have up to 18/12 ( and the problem of finding an appropriate timer.) Personally I am looking for someone who has experimented with this already. I understand hesitation on experimenting on a crop that is close to harvest.
Maybe someone could make a timer if this idea is of any worth.
Member Torantoke and I have done the shorter lighting thing - Not the best idea to go much below 9 on.
As for blooming for long hrs. Unless the plant is already
in bloom. Your not going to get very far.
Some indica's will begin to flower
around 14 hrs of light. Not many and they tend to be at 14 or less hrs, not more then...Sativa's will be more around 12-13 and even if you have the sativa in bloom already and then increase time. The plant will revert to veg..
See above...
