"That basically looks what's called a fluidized bed filter (in the aquaculture industry)...in aquaponics (hybrid designs) it seems like folks 'usually' have enough bio filtration, but not enough solids filtration ( like Jeremiah…"
"Last year when cold weather hit I rushed and built an 8x10 GH. I was happy with the results but struggled to keep it warm. This year I am expanding to 14x21 but will be able to reuse the walls. I am anticipating no further growth but will be…"
"I did a bunch of research on SCHS for a customer recently. They're gangbusters for cooling, but heating gain is minimal. The real winter advantage is that they heat up the ground earlier in the season, which doesn't do much for…"
"It's basically a bucket that the water flows through that's filled with these with an air stone in the bottom. It will do your nitrification for you (i.e. no media in your grow bed needed) if you have one of them, though,…"
"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…"

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…"
I looked to see if a topic existed on this already, but could not find one through the search function. I am interested to know what uses people have come up with for their used rockwool. Any rockwool that is in decent enough shape I will usually…See More
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.
