Advantage/Disadvantages running lights on 24hr a day for Veg.

Are there any disadvantages to running my lights for 24hrs a day during veg? Other then the Electric bill. Any Advantages???

i've NEVER ran my lights at 24/0. never. i see no reason to.

I am only considering it, because I don't want to invest in a heater for basement grow room. When the lights go out The temp gets down to almost 50 for the last hour and half or so of night. I go dark at around 12:00 noon, so that the temp is at it's warmest. I will not have to worrie about this for long, as it will be getting much warmer around here. But for now, I would like to maybe run 24hrs on. Does anyone think it will hurt the plants, or maybe even help them grow faster?

it doesnt hurt them. go for it.

I say switch it to 18/6 to give it a more realisitc cycle. This way the plant has time to rest and generate the sugars it needs when the light goes out. Keeping it on 24/7 is only a waste of energy and will not make it grow significantly faster.

what are you running?

Right now I have a 400watt MH set up. I have another 400watt Hps with a MH conversion bulb on hand, which I will be adding for flowering along with 6 36" floros to run along the side of my grow space. I just added a carbon filter and another air intake. I have a few fans set up to keep the heat down, and build up the stems.

There has been a lot of experimentation on this issue on another site that's frequented by expert growers. Based upon their consensus, I tried 20/4 for vegging on the grow I just harvested. Tightest nodes I've grown yet ... with the resultant fat, chunky colas too.

I like those results. What equiptment you running?? I may just stick with old 20/4 and take a chance. I added some more insulation, so the only ouside air getting into the room is from my intake fans.. The temp stays above 58 now. About 5 degrees warmer then it was.. I can live with that.

i veged mine in 24 hours of light it didnt harm the plants or anything and i didnt get more males to female ratio i got 50/50 3 males 3 females

swim,

ran his 24/7 for 4 weeks with similar problem, basement was cold. And his G-13 nothern light's crossed with skunk grew with outstanding measure! Swim is also rolling on a 1000watt MH

I have also used 24 hr lighting with CFL bulbs. I grew 2 healthy females with no problems at all.

Swims, Seeds were feminized, so no worries.

If only swim would post pics....It could potentially change many doubters on 24hr lighting. I am currently running 400w hps and 400w mh 24hrs with great results although she is only 4 days old today since seeing light.

As soon as I understand how to attach theses damn pictures I will.

lights that stay on for 24hrs run cheaper then lights going on & off all the time

Allright here they are first grwo so be easy

By the way the plants are 6 weeks old at the time of those pictures

phenominal....I love those pics! I hope I can get some similar results dammit...ha

my jorge cervantes grow bible says that 24 hours of light will increase the number of males.
