What are your lights?
What is your ventilation?

If you are grwoing an Indica strain you could be OK with 36 plants in 8" pots SOG.

If you are growing a Sativa, you could be ok with 2-4 plants in 5 gallon pots ScrOG method.

A 4x4 would give adequte breathing room for 4 plants if this is your first time. If you cram the growth in there without proper ventilation and knowing what you are doing you could run into a learning experience rather than a successful harvest.

Good luck and read read read.
blink_inc Reviewed by blink_inc on . Grow Box Help. Is my Setup Good? Hello, I'm in the process of doing the research to build a grow box and grow some of my Miracle plant. Attached is my general box blueprint, along with airflow plans. Will this work ok? Any other things I should keep in mind? How much power should I use for the intake and outtake fans? Also, I was thinking about putting a overhead 600w light. Would this be enough? I plan on growing 1-2 plants. Let me know! Thanks! Rating: 5
