I Want to share the design of my room before i start the work. If you see thing that is wrong or could be better another way, please share. I had modified my setup many times thru my firsts grow and i want to redo it for a long time. The goal of this setup is to harvest about once a month or a bit longer depending on strains. -The room : is in a basement 13x15 Actualy it's a 9x13 room but im about to move a wall. The room have 2 adjacent wall to the outside who's gona be insulated with 3inch foam, and the others wall division will be insulated with fiberglass batt for sound purposes. -Flowering : Im planning installing a 4x8 tray in the center of the room for the flowering who will be "open air". Im planning splitting it in two zone, so each month i harvest one side. There will be two independant cob fixtures (~600W each) to accomodate two strains height. -Mothers / Clones : I've got an existing 2x5 homemade tent to keep mothers and to starts clones or seedlings. Im not sure if i should keep mothers or i should take cutting from vegging plant and only use the tent for clones and seeds. Inside there is a 200w COB fixture and a 120mm that will circulate the air thru the main room -Vegging : I have an existing 4x4 homemade tent that i'll use to veg the clones while one spot become free in the flower zone. I'll use a 1000W MH that will eventually be replaced by a COB Fixture, not sure how much watt. The Metal Halide will be inside a vented hood on a 6 inch fan that will intake and exhaust to another room. A 4inch fan will recirculate the air to the main room. -Cooling : Planning on installing a 12 000BTU Mini Split but i'll try to use my 8000BTU Portable AC at first for the spring (The AC Has an intake and an exhaust so the condenser is completly isolated from the room and i'll not flush odors outside...) -Dehumidifier : I'll try to find something over 100pint or im gona use two smaller one... -Ventillation : At the beggining i was planning on venting thru a cheminey but i was aware of being spotted by FLIR so instead im planning on venting to the basement with a 8in fan and 10in carbon filter. The fan will be constantly running on low to keep negative pressure and it will cycle at high to maintain a minimal co2 level. I'll have to buy a co2 meter to check how often to run it and if inside home co2 will be enough or i'll need to take air from outside. A passive intake will be installed in the window to let fresh air in cold weather or to replenish co2 level. My biggest concern is : will the A/C and dehumidifier will be enought to not occasionnate mold problems inside my house. I Dont really want to vend hot air outside in fear of beeing spoted. I Think the mini split unit outside is stealth. -Growing Technique : I Plan to harvest 4 plant per month so there will be always 8 plant in the flowering. I Was planning on installing screen to Scrog in the flowering but im not sure about that, only tried it only once and i was training the plants in vegetative phase and flip to 12/12 when the net was 2/3 full. Is it a good idea to start scroging them while they start to strech? -Medium : Coco Drain to waste -Watering : Everthing exept clones will be on an automatic watering system that im curently using and working pretty well. Not that im too lazzy, i'll be visiting them at least twice a day to check on everything and adjust PH What do you think?
