Advice on new grow..

Hi I'm thinking of doing a grow with subcools super soil in 20ltr airpots in a 3 x 1.5 x 2m tent using 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 the 20ltr airpots half full with super soil how long should I carry on vegging to get a nice root mass before budding? I'm thinking of doing big bang as they're meant to be 9 weeks but my friend has lemon haze and cheese cuttings so not sure which to go for any input or advice would be much appreciated. Also should I ph my water with super soil? I'm using bubbled tap water which is normally 7.6-7.8.

one the plants depend on your strains u pick and the skills u are using

letting it go natural 1x1m for my largest

as for subcool's soil aslong as u mix it up with the correct soil (ones with Mycorrhizae and other fungi/bactrea) allow it to rest for 4/6 weeks in the warm sun adding a gallon of water a week to it (allowing the soliders to grow in the soil and get a good balance) ...........yes u can just water with what u have

if u are just mixing and using then u need to feed/supply with the micbros to get it started faster for u to get the full goodness out

as for the time i can have a nice root mass in 40 days but i grow autos from seeds as for photo plants u can use the transplant method (autos u can not) so this means u can get some cuttings from your buddy root them in water and then transplant it to a soil system (like happy frog do not put seedling/s fresh cuttings in with subcool's he even tells u it is too strong for this)

Get 3 600s instead of 2 1000s better footprint almost exactly the same amount of light. And I would say between 4 an 8/plants depending on how big you plan on getting them.
