Need some expert advice on our Garage grow in AZ. We have two 5X5
Gorilla grow tents one flower one veg/clone with 1000w HID dimmable lamps\hoods in each - Balasts are outside the tents mounted on the ceiling and controlled by a 220v Titan dual trigger 8 light controller connected to the iponics. We are planning the ventilation and AC now, but are confused about venting and intake in relation to CO2 enrichment. Currently we have both tents exchanging air using 10 inch fans and 10 inch ducting between the two tents and can control the pressure using the speed controls. There is a huge charcoal filter (overkill I know) in the veg tent scrubbing the air using a 10inch fan with speed control. We have a large window unit 12k BTU (again overkill I know). We planned CO2 enrichement using tanks with regulators. We have an iponics controller to monitor and control everything. We are planning on putting the AC inside the garage pumping cold air into the veg tent (which exchanges air with the flower tent rapidly) by making an adapter over the front and a short 10 inch duct into the tent - we are not sure if we need to duct the exhaust outside or if we can just leave it in the garage (probably will be too hot and will have to vent outside - thoughts?). Lights have separate ducting to cool them that goes straight through using 6 inch ducting and a 10 inch fan with reducers pushing air to cool them through each light and out the other side of the other tent.
So at this stage in planning I need to understand some things.
- Since we are using CO2 enrichment do we even have to vent (I guess technically we will be venting in a round about way by using the AC)?
- Do I need to worry about the AC exhausting all my CO2 enrichment?
- If we need to vent what would be the best process in relationship to the CO2 enrichment, Temperature, Humidity, and O2 desired levels? I can make the controller turn the AC/CO2/Fans/Lights etc all on based on time and or by measurements of temp/co2/humidity etc using the iponics.
- Do I need an intake to balance out the air being exhausted out by the AC and or alternate venting if applicable?
- With this setup the scrubber will be next to the AC which is exhausting the hot air out into either the garage or more likely outside. Smell is a concern so between the huge scrubber and the AC filter I am hoping there will be no smell - thoughts?
- And just because my wife really likes the idea of a portable AC inside the tent instead of using the window AC I mentioned can anyone give us advise on if we should switch? Would the portable work inside with or without ducting the exhaust? Her hopes are that we do not have to cut a hole in the garage and duct either AC outside but I think we will have to.
That is probably enough questions for now as I am sure I will have more. Happy to take critisism as I am new to this and advise is greatly appreciated. After we get this setup working and have learned from all the mistakes I am sure we will make (3rd time a charm is what I hear) we plan to move to a larger setup. Thanks again in advance for reviewing my post and I look forward to reading the responses.
