AFGHAN

iam hoping to grow around 40 afghan plants from female clones but there are many questions i want to ask
i will grow organically

*should i use a soiless mix or soil
*will they finish before october
*who produces the best strain sensi nirvana kcbrains
*should i grow a singled stem plant or pinch out so there are multibranches
*how big should the hole be that i plant them in i was thinking 4ft deep by 3ftwide

what yield should i expect from them

im growing outdoors in the uk

should finish by october, it is pure indica. use a soil mix and your hole is good. Let it grow naturally for best results (called tree style) and sensi has the best out of that list, but it is not the best of the best.
