Hey everyone. I'm getting close to the end of my first grow, and planning my next. It'll be running 2 1000W HPS. I'm going to start off with this tent: High Tech Garden Supply Two of these guys High Tech Garden Supply This for venting the lights QUESTION: Do I need two of these (one for intake, one for exhaust) or just one? Valueline 6 Inch 435 CFM Centrifugal Inline Fan - Plantlighting Hydroponics This for between the lights Suncourt 6 Inch In-line Booster Fan w/powercord - Plantlighting Hydroponics I need help with air circulation for the tent itself. I need a blower around 700cfm, correct? What other things do I need to complete the tent? EDIT: Forgot to mention, it'll be running a 4x8 Ebb & Flow tray with 40 plants on a 1 month (20 plant harvest) rotation. Vegging will be in a separate area.
