also i want to buy a wilma system , would a 8 pot 11 litre be suitable ? or a 10 pot 6 litre ? what is the difference between 6 litre and an 11 litre pots ?

thenks in advance

Hi, I used a Meizhi 600w (similar light) for my first grow in a 16ft² space, and it lacked on its own.
Running 2 600w models in a 4x4 area would probably be satisfactory, but they still might lack in the flowering stages a bit.

As for number of plants, that really depends on what size you grow them too (veg time) and what strains you use.
With a 4x4 I'd say about 6 plants vegged for 4 weeks should give you a good canopy.
