I have a couple of suggestions, ive been doing alot of research on installing ib in my next room.I think your chiller is to small each HP of the chiller gives you about 12000 btus of cooling power. Each 1000w bulb gives off about 4000 btus of heat, so with a 3HP chiller you have 36,000 Btus of chilling power, and you are putting out 48,000 btus of heat with the bulbs.I also think from looking at your pics that your ballasts are inside the room, if they are get them outside, each 1000w digital ballast is equal to 2400 btus of heat, thats another 28800 btus of heat. I know that in Hydro innovations video they have their ballasts in the room, but they had an industrial chiller, they dont say how big it is, I think because they dont want people to know how much they will really have to spend on a chiller. If you are trying to use the ib for a/c you need at least a 4 HP chiller, I would run a 5 so that if you want to cool your rez if you set up aero or if you get a water cooled CO2 generator it will be able to handle it. Pick up a copy of the Jan/Feb Urban Gardener Magazine, there is a really good tech article on water cooled gardens.
I would not use your well as your primary cooling source, I dont even want to think about how many gallons you are pulling out a day, it WILL fry your pump very fast, and then you are in alot of trouble, in the hydro innovations they have well water for a backup only until the chiller can be fixed, if you keep using your well you WILL need to replace your pump and you will probably have to get your septic system pumped, not cheap and very inconvenient.
Keep up the good work im definitely subscribed, like I said ive been doin alot of research on ib and it will be nice to actually see them in use
