Hello, fellow aquaponic practitioners! I’m Joel, a grad student of horticulture at UW, and I’d like the opportunity to visit your system if you use flood-and-drain (or ebb and flow) grow beds within…Continue

Fish for NW Aquaponics

I'm brand new to AP but have been reading and, hopefully, studying for about a year or so. During that time, I knew I wanted to have tilapia as my fish, but am fairly sure I won't be able to sustain…Continue

Grettings everyone,


Update on project:  Investors have been very generous and making it easy to move forward quickly.  We should be manufacturing our biomass steam / electric cogeneration system soon.  We also have found some interesting information that should reduce the cost of feeding the fish drastically if not eliminate it.  Everything is starting to come together.  Still a little more research to do.  We have also come up with a method of moving the water in the system without the use of water pumps.  It should reduce the energy cost of moving the water by about 75 percent.  I hope everone is doing well, I will keep you updated as we get closer to completion.

Hey everybody!

I finally found my steam engine.  So, next part of the project is the boiler.  It will be a centralized system, that will heat two homes my shop, and the greenhouse.  The boiler will of course, power the engine as well.  I have an engineer working on the boiler design which will include a biomass pellet fuel system.  That way I will be able to fire it on cord wood or biomass pellets.  The engine will generate electricity to charge the batteries that will be powering the aquaponics system.

I also found a very inexpensive source of recycled tempered glass.  3'x6' panels for $5.  I bought 40 of them to use on the roof of the building I posted photos of.

I have recently found a few sources for the 275gal. IBC tanks in the Tacoma Seattle area.

Hi everyone, sorry I havent been very active here.  I have had a large woodworking project get in the way of finishing my greenhouse.  Still working on the heat and power system.  Should be back on track in the next few weeks.  I hope all is going well and hope everyone is getting ready for spring!

Hi everybody,


I have narrowed down my choice of steam engine to two, but both require machining.  I have acquired most of the equipment to build, metal lathe, drill press, and other misc. pieces.  But I still have to get a milling machine.  Almost there!  I have a couple of boiler designs that are fired with biomass pellets.  I am collecting material to begin building the boiler as well.  It has been a bit of an adventure.  Should be glazing the greenhouse soon and then adding the coldframes to both sides for the cooler weather crops.  I hope all is going well for everyone.  Take care!

Thats great Nathan!  I will have to go check that out.  I am finishing up my greenhouse, and will be working on the heating soon.  Then I can start setting up my system.
