I agree with 2much, as proper flowering develops proper buds. give your girls time to grow strong. If you started at 12/12 you would have little premature buds. just grow dwc& bubbles and harvest 6 plants every 3 monthsmain thing is you want to give it time to build a healthy root system to support the flowering stage, small root system, small buds
i do 18/6 veg, then 12/12 to trigger flowering, good luck
I have the same issue, I'm currently doing a garbage can grow with 5 plants, but i will veg for about 2 weeks for extra yeild and trying something I havn't done. I have grown a clone from 12/12 from the cloning process to finish, it produced 10g of the best bud I have smoked. If you do 12/12 straight from seed it will keep your plant short, and it will finish at 10-14". As a generality it will be denser, though for how dense and short it will be will be effected by the light spectrum. A 5000k-6500k spectrum will be what you would wan't for dense buds and a more squat plant with closer nodes. If you use that spectrum in flowering though make sure you have good ventilation as the bud will be more dense and will be more prone to mold. You want to have good ventilation in a reasonabley dry area throughout until it's dried. Also here's a great article off of icmag.com.if i do 12/12 from seed will it keep my plant short and dense? because i have a small grow area.
