pleease help with a 12/12

Ok so I just started my 12/12 from seed grow today idk what strain it is but I want advice on any type of 12/12 from seed experiences. Now reason I'm doing this is because I want a short bushy plant no bigger then 1 1/2ft I don't mind if its not that much buds.? But I do not want to do (lst)!!
My questions :
Does doing 12/12 from seed mean I can't top my plant?
Does watering change
Can I start nutrients right now?
Do I prune my plant once it starts growing for a bushier plant?

I am growing on a 2x2x2 grow box with a good size fan tempatures are between 70-80 degrees. I have 3 cfls all 23w 1 on top and 2 on the sides. Covered with aluminum foil everywhere. I am also using half of a 1liter coca-cola bottle can I grow them all the way in their they are all covered in black tape so the bottle isn't clear. With miracle grow potting soil! And nutrients are tiger bloom only? I don't have the big bloom , or the grow big, wich I heard the grow big is only good for veg so I don't think ill need it? But does the tiger bloom work with out the big bloom? It is 2-8-4 (tiger bloom) Thanks for any help I can get

Seems like you'll be better off letting them veg for at least a week....or at the very least don't flower until you get your 1st node. Its only costing you a few weeks time and the pay off will be much bigger. Just my 2 cents, good luck with everything man.

Find del bhoy he has lot's of experience with 12/12 from seed!

Tried look for del bhoy couldn't find him ?

there ya go

You can grow it 12-12 from seed, but the plant isnt going to insta-flower. It's going to veg itself for about 2-3 weeks anyways, so you may as well veg for 1.5-2 weeks and then flip. I went straight 12-12 from seed and and i didnt top or cut anything at all. Im growing in a 2by2by3.5 rubber maid, so height is an issue with me as well, just make sure you LST early when the limbs are flexible. CAREFUL WITH THOSE NUTES. Seriously, i killed one of my females in her 1st week of flower because i over nuted, DONT follow the dosage on the nute bottle, go for 1/2 str. I'd even say dont add nutes at all until you see deficiencies since you're using MG soil which is pre-treated with nutes. Go ahead and learn the difference between nute burn and nute deficiencies, its going to save you a lot of grows.

I guess the only way to go is lst but fuck I don't want to do that with my plant plus its alot of work.
Yea I stopped the nutes I read about it.
I guess ill just destroy my grow box and make a bigger one.
I went to the 12/12 from seed thread that guy has over 600 pages lol good day of reading but
I would love my plant to look like that I see Ima need a short bushy seed
Strain as well.
Thanks for your help you guys if anything ill try the lst learn more about it?
