I already have a grow on a tent set up within a room (my first grow) so im grasping the basics and looking to learn at every point. Ive got the opportunity to start a new grow room purpose built approx 3.5m lenght x 2m wide x 2.4m up. Looking for good ideas to get going. Including drainage ideas electrics fans and size. I can have build in air bricks but dont want light escaping, roof vents. I can have running water within the grow room. Thinking about a trickle system (not looked in too much depth yet). I dont really want to be moving my plants this time to water etc. Looking at scrog aswell So any ideas welcome, you got a ingenious grow space??
