My biggest questions are Ventilation/AC/CO2 based.
Ok so this is a rough floor plan... those orange areas are representative of gorilla grow tents starting counter clockwise 4x8 8x8 8x16 10x20 10x10.
Clearly way over the top and unnecessary. If I could just do two 10x20s I would but the square in the middle is the area dominated by the furnace. The circles with x's are support poles and everything else are walls or stairs even the unmarked edges of the page is a wall.
Its is best to have fewer atmospheres to control so the 10x20 is a given and the 8x16 is the next best option.
I have 8 digital ballasts and 16 hps cooltubes. I want to go led but these were too cheap to pass on. I'm wanting to put 8 in each tent and flip the ballast back and forth. I can get the light speed flip16 controller for cheap. Its a Canadian company but I can't find any reviews or any other info about them.
I haven't bought an AC unit for the house yet because I'm waiting to determine my grow needs before deciding.
I want to use CO2 so when it comes to cooling my grow rooms Mini Splits seem like the only reasonable choice.
I was put off by the idea of designing an AC system for a temporary light choice but noticed that cooltubes can run up to 50 percent cooler that non air cooled lights. I also noticed that leds use roughly that much less power... which produces that much less heat... so it will be roughly the same btus entering the grow room regardless.
I know that 8 1000 watt lights even if they are air cooled is alot of heat in either tent. I've read some threads claiming that I need between 3400 and 4000 btus per light and I understand why. I know that I don't want to oversize my AC by too much either
So here are some of the questions.
Can I put two units in the tent to drop the cold air down evenly and push the hot air up to be cooled?
I will never be running both rooms at once so do I need a system for 8x btus or 16x btus?
I have natural gas available to me from our utilities provider. A co2 generator makes alot of sense except for all the added heat. I'd like to find some more info to get a handle on that.
I will likely be adding a few more tents but only when it makes sense to do so. For now I have two similar size grow spaces.. extra room and extra tents. I was wondering if its possible either for cooling or for co2, to create a third room where the cooling and co2 generation can take place at all times. Then just control which room it is operating to switch back and forth. Similar idea as ballast flipping but for AC and CO2.
Ventilation when using co2 and air cooled lights is very confusing.
In order to get cool air to pass over the lights I need to pull it from inside the house where the aor is cooler than the outside and then exhaust it outside.
In the winter I would need to do the same because that air is just too cool...
So if I'm dumping cool air from inside my house in the summer and warm air from inside my house in the winter. What kind of strain am I putting on my furnace in the winter and my houses AC in the summer?
So I was thinking that during the winter I would exhaust that clean heated air back into the house to ease the furnace requirements. Why waste it?
Of course once I upgrade to LED there will be no air cooled Ventilation....
So you could address all my questions or just tell me what you think I should do instead and I can draw the inference.
Thanks for any advice in advance.
