Need experienced growers opinion

Judging by experience, how much do you guys think 6 plants under a 400watt hps would yield in a 3ft4in x 3ft4in x 6ft grow tent? I plan on going with the strand chronic and im hoping for at least half an lb.

Also, do you think I could get away with putting a 1000 watt in this space without alot of issues?

Hey Edi.....

If your plants stay healthy, you should get 8 ounces..

If you can control the heat, then you use a 1000.. and your yield will benefit
greatly!
