12/12 from seed training methods?

No. On a 12/12 from seed, you basically just let them go all natural. Anything you do will stunt the growth and progress. Just let it go! ✌️🏻💚🌿💨

Yes having done a few 12/12 from seed I don’t recommend topping - I don’t believe you’ll have enough lateral growth to do a scrog. I would leave as is - you will likely see a main cola type growth from it regardless of whether you take off lower growth or not. I wouldn’t overthink it at this point. You don’t wanna cause serious stress right around the time it might be transitioning to flower - which you are pretty much guessing that will be when you do 12/12 from seed. If you aren’t worried about the product and end result and just wanna learn form experimenting.. go for it! But otherwise I would let it do it’s thing

I might avoid topping if you're going 12-12 from seed. Topping is pretty intrusive and an aggressive form of training. The plant will need time to recover from the topping, and it may cause problems if the plant is already thinking its time to flower and focusing all of it's energy on that. I would do LST and tie the plant down instead. Then when new shoots start growing as the plant starts stretching, you can tie those down too to expose more potential bud sites. LST is less stressful on the plant and if it's going into flower right from the start, I would try and have as little interference as possible. If you really want to top, maybe consider extending the light cycle and let the plant veg for a bit until it recovers from the topping. Once the new growths have 2-3 sets of new leaves, switch back to 12-12 and let her rip. Hope this helps. Cheers!

Only reason the topping is considered is due to her showing no pistils/maturity just yet so there may be a short window.. Just maybe?
