12/12 from seed?

You can't run 12/12 from seed you need to do research homie you need 18/6 to 24/7 tell they veg large enough to 12/12 them besides all that your light needs to be at least 150 actual watts to support the plant finish to end I would get at least a 250-600 watt light your choice led cfl hps whatever you choose do some research don't just start head in first that's a mistake

You can run 12/12 from seed if you like but there is no purpose to it because a plant won't go into flower until it's mature enough. All you would be doing is depriving the plant of much needed light for growth.

 

And almost no yeild from it

Like others said already, you can do it but out doesn't make sense. Veg it 18-6 for minimum 2 weeks where your plant would have enough energy production to fuel flower.

Check out my first grow log:

First ever grow: How do the girls look?

 

I had 7 bagseed plants under 12/12 from seed. Yield was a bit over 4 ounces. They took up like 1/4 of my 4x4.. so if I had filled the space.. we'd be looking at one pound every 2.5 months or so..

I don't recommend switching to 12/12 until they're mature enough to flower, but that's certainly not "almost no yield"

 

That's okay I guess but that's nothing compared to the autos I pull in that time frame or less at around 2.5lbs in a 4x4 under led but photos have the potential to produce lbs in the same area per plant
