Over the weekend, I bought the stuff I needed to go through with creating cooling jackets in the outer walls of my chamber. The chamber gets way too hot here. Unfortunately, after imagining the logistics of it a little better, I doubt my plan would work of running some cooling lines through the wall pockets filled with water. The heat and sunlight would just overcome any attempt, plus is would be a great waste of electricity-and it's 3x here the price on average of anywhere in California, we have the highest electrical rate in the country here. I even considered trying to use micro sprinklers to spray cold mist into the walls, and recirculate it through my chiller- same issues though. My original idea was to used closed cell spray foam (great stuff) in the walls. I chose not to after reading it expanded with such force, it would likely distort the chamber walls alot, plus it outgassed alot of toxic fumes. Now I am in a rut because it's probably the best way to insulate the pod, but will be much harder with everything put together now. In the end, there will be 2" thickness of foam in most places, but due to the structural geometry they incorporated into the molds, some places will be less thick. I read tree farmer uses 3" of insulation, so I wonder if even going through all the trouble will give me enough insulation anyway. It will probably spill out through the drilled holes I make to insert the spray tube in as it expands, and make my inner chamber a bit of an eye sore, but that's not a huge deal. The lid will be even harder to insulate because the holes are already in it for the netpots. I suppose I could tape over them to try to hold it together, but it will likely get messy. If I could do it all over again, I would have insulated first, then modified the chamber, but I just didn't know. Luckily, the chamber itself is fairly easy to build, and I could just start over again with a new concept, and then just hook it up to the control center, but for now, I don't have any more money I can put into this for a while, so I have to figure out a way to make what I already have work. Any ideas anyone else might have would be welcome.
On another note, the other night I noticed all the lights in my house were giving off big beams in the darnkess, as if there were smoke in the air. I realized the fog cloner was fogging up my entire house! lol... For now, I was only running pure water in it, just to test it out. But now I'm sort of worried if I start putting nutes in how healthy that would be to breathe. I can put it outdoors but will have more heat issues, so that's just another thing I have to think about.
