New grower ! Please i need some advices thanks

Hi ,i'm a new grower.
I'm going grow for the first time and I need some advice from an experienced grower.
I'm going to use a grow box mamooth 1,50m×1,50m×2,00m with a hps 600w dual phase , 9L pots , bio bizz light mix and biobiz nutrients and the other stuff. Is 600hps enough for 12 autoflowering like : super critical(green house) and think different ?
If 600hps isn't enough what kind of led can i add ?
Sorry if i make mistakes but it's my first post.
Thanks to you all!

I would go with bigger pots than 9L ( 2.4 Gal)
You can add more light but I would wait until you know what your temperatures are going to be in the tent.
Cheers

Da...15 liter pots is best also the extras soil would proveide some insulation

don't forget that 600w HPS light is rectangular ..1st noob mistake for many .lol

give some thought to extraction and ventilation
