Tomorrow begins the construction of my first grow box. Need advice on my dimensions.

Tomorrow I intend on beginning to customise a locker I have at home.

These are the dimensions: (H) 29.9 in x (W) 15.7 in x (D) 18.9 in

Using LST and growing an auto-flowering mostly indica strain and allowing space for fans, fan light traps and CFLs themselves, do you guys reckon I could get two plants in that space?

Really appreciate any advice ASAP as I need to start building in 8 or 9 hours time

I would say you could squeeze two in. But I always have a hard time imagining tangible dimensions in reality.

You could fit two in, but it may get tight. Start with one and dial the settings in. Best bet would be to make two lockers ;p
