24/0 and 12/12 are perfect, that's why we do it, why it's published in books, and if it ain't broke.....

but see isnt it also published that the goal is to copy light cycles from nature? im not sure about you but nowhere ive been has a 24hr light cycle and most places dont even have an 18/6 light cycle... that being said does anyone that has tried this seem to have better result than the normal light cycles we all use

There is no reason for a vegetating plant to rest. No light means no photosynthesis. Trials and tests conclude that you DON'T get more roots by allowing the plant to "sleep" for six hours a day, the only thing you do is keep it from growing as quickly.

You may want to rethink the 'most' statement. If you want results and someone to trust, pm me, and I'll give you some links to read if you have a few spare weeks.

^^^you couldn't be more wrong.

plants absolutely need a resting period. in the photosynthesis process, there is a reaction known carbon reaction pathway where the free energy of ATP and reducing power of NADPH are used to fix and reduce CO2 to form carbohydrate. which is a very important process to release oxygen into the air. this only happens at night.

i run the gas lantern method, which is in every college entry level horticulture book, for my grows. it performs just as well as 16/8 did with the added benefit of showing sex nearly a week earlier and saving electricity. every horitculture business uses this method as well. could you imagine how much valentines day flowers would cost if they used the prefered lighting schedule of cannabis growers?

so are you saying that the 12/5.5/1/5.5 cycle would work better?

Are we talking energy efficiency or plant growth efficiency?
I'm not wrong, but the awesome thing about advice is you don't have to take it.

I have been using the 12/1 for nine months now. The plants are marginally smaller but more mature (leaf/stem) for their actual age compared to 18/6.
The only difference large enough to be obvious without rigorous measurements is the time to bud. A plant grown under 12/1 shows a difinite bud head within four days of 12/12, with corresponding less stretch.

Root whatever, who cares? But an extra week of real world time on the bud? that did it for me. Less stretch didn't hurt, but that bud head a week early was a display I could not ignore.

Health is up, yield is up. I am not sure why the detractors, grow how it suits you best.

. My self I go 24/0 then 12/12 seems to work for me

Poorly written article that contradicts its self.


Growing indoors you should copy how it grows outdoors. No Cannabis growing in Afghanistan gets 18 hours of light in growth pattern.

Ok I underatdn that but Mj also dose not grown in water naturly but we can Hydo just fine.


The 12-1 lighting schedule is as follows 12 hours lights on, 5.5 lights off, 1-hour lights on, 5.5 lights off, and repeat schedule. The 1 hour on in between off period fools the plants that stay in vegetative

Ok where in Nature did he find that happening?

24/0 and 12/12 results speak volumes...

















If it ain't broke, don't fix it? :cool:

Those are pix of different runs, perpetual system. I've done dirt, perlite, dwc, aero, and just about anything in between. I average 4-8 oz dry on indoor bushes, 1-2oz each dry on sog plants.

no one said 2-/4 - 12/12 didnt work. saying 12-1 - 11/13 at the very least performs just as well and saves electricity. that is all.

where it did perform better is flowering was faster and stretch was far less then 20/4 - 12/12.
