Currently setting up a spare bedroom.... Big grow need some kind tips. Peace

I am currently setting up a bedroom into a grow room.

the room is approx 4 meters squared.

I have Just bought an 9x 25Litre auto pot system.

I have up to 8x 600 watt HPS grow lights.

my filtration system is the biggest fan I could buy. Hughe fan and filter with thermostatic controls etc.

I have 9 x green crack autos from fast buds.

my question is, should I have bought some higher yielding auto flower seeds, or will the green crack provide if everything runs smooth.

is it possible to get a high yeild, if so what numbers are we looking at.

many thanks in advance.

Sounds like a few lbs to me, good luck, i had a good experience with my green crack from fast buds, made a few fem seeds with her.

Kinda hard to tell... First things first, you never told anyone what your goal yield was. 2nd... You have an awesome space but for 9 green Crack autos, you won't need that big of a room or that many 600 watt HPS lights. What is your goal yield? And have you grown autos before? Cuz it makes a difference...
