Noob question on SCROG

Hey All

I am building my first grow box and plan on doing a SCROG under CFLs
I have a couple questions

Can I grow 3 plants in a 2sq/ft area?
How much height do I need, is 36in enough?

I can guarantee there will be more questions to come ha ha. I will post photos as I go

yes you can but you should have more room depending on strain and amount of topping

36in is enough if you turn to 12.12 after a few weeks

1 plant will fill a 2ft screen by itself
