18/6. Plants cannot process more than 18 hours of light a day, so it's simply wasted light, electricity and money. If you can save money on those 6 hours of light, with no difference in vegetative growth, why the hell would you want to use 24 hour lighting?This seems to be a big debate on lighting periods in the vegative growth stage. Some say 24/7. Other say 18/6.
I'm using soil with floros. Plants are 4 weeks old - Big Bud seeds.
I don't know which cycle is best. I'm wondering if it really matters at all.
Are they going to keep them on 24 hours when they go 12/12 as well then?although what you said is correct babygro, some people use 24 hrs of light because it is cold where they are growing and it is a good way to keep the enviornment warm.
If I have to get the book to back me up I will, but Ed Rosenthal states in the "Indoor High Yeild Guide" that plants grown under continuous lighting in vegatative growth (24/7) DO get off to a better start than when plants are grown under a different light schedule. No its not going to have a monsterous effect, but It will be better than not doing it.18/6.

Why would they do that if they wanted bud to smoke?Are they going to keep them on 24 hours when they go 12/12 as well then?
His plants are 4 weeks old in vegetative growth, does what Ed Rosenthal said still apply then? I would tend to agree that in seedling stage for the first week or so 24 hour lights can help, but after that you should switch to 18 hours. I give my seedlings 24 hours for the first week or so.If I have to get the book to back me up I will, but Ed Rosenthal states in the "Indoor High Yeild Guide" that plants grown under continuous lighting in vegatative growth (24/7) DO get off to a better start than when plants are grown under a different light schedule.

My point (clearly, well lost on you it seems) was that if they have to have the lights on 24 hours as a means to heat up their environment as Meatandpotato suggested, what are they going to do to heat it up when they go 12/12? They have to solve that problem of heating sooner or later and it shouldn't be a reason to keep the lights on 24 hours a day because it's wasted energy. They need to find a means of controlling their environment temperature without relying on the lgihts - that was the point.Why would they do that if they wanted bud to smoke?
Clearly lost on you too it seems. Tsk.lol thats funny ellis.
