"I chatted with our local guy about geothermal in our area. His take is that the systems that he uses would not be able to keep up with the temperature extremes in our area so I would still have to have a conventional heater and he ran some numbers…"
"Hi has anyone ever been to the shrimp farm at Gila Bend? I think it's parcel number 402-03-011w on the http://maps.mcassessor.maricopa.gov/ web site. It's owned by az-wood holdings. It is listed as agriculture/vacant…"
Actually i only fleetingly thought of snapping a pic then didn't, I was trying to prevent anymore deaths.
My SLO was a 50mm 90° bend into the lid of one of the IBCs. I heated the end that poked through a cutout in the top of the…"
"Put an elbow at the bottom of the standpipe that goes from 3/4 up to 1 1/2 inch and use 1 1/2 pipe for your long run under the grow bed. Air actually needs to enter from the bottom to stop the siphon."
"I'm in The Bahamas, so heat and excess sun is a big issue here. I have a DWC system. I can grow basil and mint year-round without any problems, they don't mind the heat. I also grow lettuce year-round but whereas I can grow any variety I…"

Hi,I've created an auto siphon that does not stop siphoning water at a grow bed flow rate of higher than 62 GPH. Is it possible that the pipe under the grow bed is too long? The pipe has since been cut to the point marked in the picture in red -…See More
"@Timothy: I'll try giving you a shout on Wednesday, since I am busy running errands and taking take of crap I couldn't get done while working.

"has anyone considered using geothermal floor heating and cooling. the reason that I ask is that in winter it heats the floor and in summer it cools the floor. it is a lot cheaper than natural gas and more environmentally friendly then using…"
Hi Jeremiah, not sure what you mean by a moving bed media filter? I am not shying away from any option, just want to keep it as simple as possible. From what I've heard the media grow bed serves as a biofilter quite well..
Actually, once you have them set up nicely.. tack them in so that they cannot move and I have found them to be no problem whatsoever, and easy to adjust if you need to. Just cover the tube so as not to let light in (to stop algae)…"
My thinking is an angular aggregate (like crushed limestone) set to a minimum pack-able depth might work very well. While a smooth floor surface might possibly allow a more free flow of liquids on their way to the drain, the benefit of…"
"I don't have any special thoughts on them, other than that they store a lot of heat. I wrote up the theory behind it here. You might find some out there with a google search.
