So it's been a while since I've done a grow... years now... and I'm starting another. Just a couple questions. 1st question. I know the current setup I have will work just fine, but is there anything very wrong that I should be correcting? Tents: Panda film & PVC frame Each tent has a stick on zipper on each side and is velcrod at the bottoms. Completely light proof. 1x 5'x2'x7' veg/flower tent (10 square feet, 70 cubic feet) 1x 2'x2'x7' mother/clone tent (4 square feet, 28 cubic feet) Lights: For clones I have 1x 23W 5000K CFL on top half of mother/clone tent (above exhaust and mother to retain some heat); 18/6 Lighting For mothers (will be 2 bonsai) I currently have 2x23W 6500K and 2x23W 5000K CFLS (will be switching to 45W blue/white LED panel); 18/6 Lighting For grow tent (for 4 plants) I have a custom made panel w/ 4x 100W 660nm LED, 4x 100W 630nm LED, 4x 100W Warm White LED, 4x 100W Cool White LED (all will run at about 60% for a total of 1000W actual watts), 1x 40W 4ft UVB fluorescent for end of flowering, and 4x 10W 730nm LED for "bloom booster" Flowering will be using 13/11 lighting with 20 minutes of IR (5 before lights out, 15 after) for phytochrome manipulation In veg I will just use the cool and warm white lights at 18/6 All lights will be off during the hottest part of the day (around 3PM) Exhaust: 8" can fan max Exhaust fan connected with 8" R8 insulated ducting to top of grow tent Bottom of grow tent connected to middle of mother tent w/ 6" ducting Bottom of mother tent using passive 6" ducting as intake Medium & Grow Method: Clones will be in a DIY 8 station bubble cloner w/ a 70*F aquarium heater Mother will be a soil mix w/ potting soil and perlite and some castings. Grow will be a RDWC/E&F hybrid system (controlled with multiple arduinos, a raspberry pi for a database/web server and multiple sensors). I plan on using 2" net pots with no medium other than water in 5 gallon buckets. Scrog with screen 1' above tops of buckets Nutes: RO Water GH micro and bloom Rhino skin Trying to stick to 1-1-1 for veg and 1-2-2 for flower at around 2 EC max Environment: Temps are under 80* F Humidity is under 60% Will be using A/C as necessary Strains: White Rhino Amnesia Additional questions: So this Is my first time using a can fan. I didn't realize just HOW STRONG they are. It's separating the sticky part of the Velcro and zippers from the tents and they are losing their seal- ON LOW . How can I get the Velcro and zippers to hold up to the exhaust fan? If the Velcro and zippers won't work, what else can I use? Thanks!
