Hey S&D,

that looks pretty much ok, just a couple of things. it looks like you've got 2 seperate air intake/outake systems, one for the light and one for the cab? You can probably get away with one, just hook it up so that it sucks air from outside the cab, through the light and back outside the cab, you can put your filter on either after the fan outside the cab or inside the cab before the light.

You've not got a lot of height to play with so you'll have to look into some techniques for keeping your plants short, Topping, LST etc.

Good luck!
