you need to give us an idea of your grow room dimensions, what style you're growing in and what size lights you are talking about.

4 600w HPS in the corners and one 1000w in the middle, That will light 10ft x 10ft, really well and have you a huge, high yielding garden.

I'd suggest 4 plants, so if you get caught your time won't be so bad.

But for 30 plants, as clones they could be flowered after rooting in a box size 1m x 1m with a 400 or 600w light.

as plants from seed you could fit them under 2 lights in a 2m x 1m box.

Why have you decided on 30 plants?? do you have 30 seeds??

To work out your required wattage you work out your grow area in square feet and multiply it by 50w (optimum).

(10' x 10' ) x 50w

= 100 sq ft x 50w

= 5,000 watts of light is the optimum.
