A cubic meter is not enough to grow pot in a fully-contained outdoor setup. You will lose so much space to gear and insulation and climate control crap, you might as well just grow outdoors.

Set up a tiny veg space indoors to get your seedlings started in about March or April so you can set them out well-rooted and healthy after last frost.
stinkyattic Reviewed by stinkyattic on . 1 metre square grow room - scrog grow - advice needed Hi I am building a 1 m2 grow room in an outside location (an out building). I plan on using a 1m nft system, 400w hps with cool hood, 150 fan with carbon kit. I will be growing scrog and think that a meter should be enough height for the set up if I have the screen at 10 inch. I will be lining the box with insulation, plastic sheeting and mylor. There will be a small fan to circulate air and an intake whole(no fan as Im not sure i need it?????). I will have a msall heater for the winter Rating: 5
