How many run 24/7 lights?

Just wondering what everyone does. I run 24/7 and my ladies love it. Top growth is amazing and my root mass is just as good. I grow in a cold basement so the light enables me to keep my grow rooms from getting too cold. What's everyone else running for light schedules?

I ran 24/0, 20/4, and 18/6 and i've only noticed 24/0 being more beneficial if you have a lot of C02. Plants need to rest IMO. Mimicking nature is the best way to do it I believe.

i once read that plants grown under 24 hours of light would grow 33% faster then plants grown under 18 hours of light, so naturally i was all over it and switched to it right away...
ime, the plants seemed to grow a bit slower under 24 hours of light then they did when they got a dark, rest, period.. and they surely didn't grow any where near 33% faster like i had read..
i went back to 18/6 and haven't looked back..

I run 20/4. I feel like the dark cycle makes them stretch slightly and my tent cools down for a while. Also I like to have my shit off in the middle of the day for stealth.

Thanks for the reply. Mine get plenty of rest during flower. I've tried it all different ways and for me 24/7 gets my plants bigger quicker. I normally veg 5-6 weeks. 90% of the time they are showing preflowers before I even switch to 12/12.

amount of hours has nothing to do with showing sex in vegging plants, it's all about how old there are.. i never flip till i see sex either, and like i said, i run only 18 hours a day..

I have a woodstove which I run if it gets really cold. The constant light actually saves me money rather than paying 250 for a cord of wood every month.

I only run clones. I just think they mature faster with constant light.

I agree. I was running 24/0 for weeks but now 17/7. More growth after each dark period for sure

It would make sense to me that 18/6 shows pre flowers before 24/0. The constant light means nothing but vegging hormones is being produced by the plant. But that's just a guess

My theory is the faster they mature the sooner you see preflowers.

Another positive thing about 24/7 is growing outdoors. I started some indoors last summer and put them out towards the end of June. They immediatley went into flower and I harvested the end of August. 4-6 weeks sooner then most other folks.

So weird...I just read this on another thread, posted by I forget who.


In the words of Ed Rosenthal:
"Cannabis under continuous light will grow 33% faster than the same plants on an 18-6 light regime."
I have no idea if its true or not though.

I've done 18/6 on my last grow and 24/0 right now and noticed nothing different. That would be because i'm not very observant but 24/0 works for me so i'm sticking with it.

Right now i just put my 1 month old clones in with my flowering plants under HPS for 12 hours (added blue spec) then 12 hours under 1 23w cfl to save power and i'm
still satisfied with growth and node spacing.

Here's my 3.5 week old purple kush clones. 24/7 lighting since get go. Just transplanted into final pots yesterday so there a little rough right now. Plants were in 1 gl pots and almost rootbound when potting up to 7gl buckets. 2 more weeks in veg then switch to flower.
