Advice on new grow

Hi, I'm thinking of doing a grow with subcools super soil, using a 3 x 1.5 x 2m tent and 20ltr airpots. I'll use 2 1000w lights with 6" cool tubes. I was wondering how many plants I should do without overcrowding? and if I veg for 2 weeks in 6ltr pots then transplant into 20ltr airpots half full with super soil how long should I veg for before switching to 12/12 in order to get a good root mass and nice size plants? Also should I ph my water with super soil? I'll be using bubbled tap water which is normally 7.6-7.8..

These are good questions, but most will depend completely on what strain you're growing.

I dont know anything about supersoil, but you always want to adjust your PH to the correct levels. PH causes the most problems for new growers. If your using tap water, you will want to let it sit for a couple of days in the sun to evaporate the chlorine that's in it; it's bad for your girls.

Hmm, a 4x8.....8 plants well vegged. Topped, lolly popped and super crop to give the height space if need be.
Set to flower when they reach 50 - 60cm (I haven't counted weeks or days for years) Being new to the game, PLEASE skip Sativa's for now. Idica's and cross's are going to be your ticket.
For safeties sake. pH your ingoing water to 6.5. Forget about pH of the soil. It self regulates. Consider a simple AACT bio tea for use about every 10 days to 2 weeks. that helps introduce fresh living bio's to the soil and helps in the overall pH control along with the conversion of nutrients in the soil to plant usable (The action the bio's provide).

Do it!

Ok yeh I will bubble the water for a few days 1st. I have some ph down left from my last grow so will keep it 6.5 I've done big bang autos before in a smaller tent they're mostly indica and stay small and bushy I was going to try super cropping and lollipoping I'm not sure about topping as that is the nicest bud.. Do you think 10 would fit in the tent ok it's more 10x5 I'd like the plants to be about 1.2 metres max

And what is aact tea? I was going to top up the soil 30 days into flower with more super soil.. I've heard teas are good for extra nutes if they show signs of yellowing

Oh and I'm not doing autos this time as they took alot longer than they were meant to
