The box has mylar on the walls already inside. What should I use for a fan and odor control? What would the best option be?
How many plants? What kind of lights do you intend on using? Dimensions of he grow box? Method of grow; hydro or soil?
Do you want a hood for the lights or are you going to put them at the highest point? I would scrog the box. Veg for 2-3 weeks and then hit them with 12/2. LSt too... You do this and you can get a quarter pound of good stuff. All you need is hood soil and forget about much nutes. Happy growing..
4 oz is not going to happen, sorry to dissapoint you, 2oz is pushing it even. Only smart way to go about doing this is.... 1. Soil as grow medium 2. L.e.d or 100w cfl 3. You need some kind of exhaust...negetive pressure will work better (having an exhaust fan, rather than an intake). Drill a 4" hole with hole saw, or jigsaw, computerfans are next to useless. Unless you got a few of them in their. 4. Have a fan(s) in the grow cab blowing on the stems
id say 1.5 oz's. pick up a 70 watt hps for flowering and run ducting from either side of its hood to the back of the box then take 2 comp fans to regulate air. Walah no heat issue and barely any noise. For smell simply build a small carbon air filter out of a foldgers tin and attach it to the intake.
