Well suffice it to say that where I’m currently living won’t allow me to build or house a tank indoors. Outside is my only bet. My plan is to build a simple tank similar to Terrence Brannon’s (http://www.thedeepself.org/2011/03/version-2b/) – to start with anyway. I’m located in Florida. Obviously the usual precautions regarding electrical equipment outside apply. But would extreme heat or cold affect the float experience? Humidity and condensation come to mind. Also the tank will be virtually useless in the winter unless I find some really decent heaters. Or when it’s raining for that matter, because of the obvious disruption. Anyone with tips or experience in this regard? Maybe not even a wise idea? Thanks!

I’m currently building one outside too.
I think it will be okay, even with rain. I mean, rain is calming anyway and it would only be occasionally.
Heating is the problem I am running in to now as well. Gas water heaters are f'in expensive! I have no idea why, it’s basically lit gas heating a tube with water running through it. The cheapest one I’ve found is \$2000. Because you need one with titanium or aluminium heat exchangers (the pipe) so that it doesn’t get corroded by the epsom salts.
I’ve been contemplating getting a gas outlet next to it, and just making a box out of aluminium sheets and running the water through that until the water gets to the right temperature and then I’d turn the gas and pump off.
If you find a good gas heater which won’t bankrupt me though, let me know.

For the heat loss terrence was talking about, I put an entire roll of insulation just for the bottom. I used EarthWool brand because it seems to be the best.
One problem I see is during the winter, if you have ventilation it may get too cold. So it might be good to plan for that. Use pipes that you can screw a cap on to the end of. And the cap could have smaller holes in it, for the winter, and an open end in the summer.
I think for an hour float you wouldn’t even need any ventilation at all. But don’t quote me on that and stay on the safe side I suppose lol
