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

Foundation is almost ready for greenhouse. Fill the blocks and install the j bolts, then I can begin assembling the greenhouse.

 I also picked up an old pellet stove that I am going to refit into a water heater. By putting in a water coil in the firebox, and a circulating pump, (and a few other things), the pellet stove will heat the air and water in the greenhouse.

My steam engine arrived today. Very exciting and a daunting task to finish. Boiler is next...

Hello everyone,

Steam engine is in New York and soon on its way to Seattle. Then I get it through customs. I have been working on a boiler, and have found a few used ones in the mid-west. I have also been researching solar panel construction and led lighting to augment the short winter days. Have been building a few greenhouses as well as a glass greenhouse for myself.  Collected some perch from local lakes and relocated them in my pond. Clearing space for the greenhouses and boiler room. Need to remove a few more trees and bring in some filldirt to level the space.  Also plan to dig a groundwater well to supplement water resources. It has been a busy summer so far and no end in sight...for projects that is. Summer is going to end to soon.

Has anyone thought of running AP water through double pain glass to grow duckweed? I'd think if used in a greenhouse set up would lower the cooling cost, acting like a block out screen or shade netting.

   I'm working on the duckweed crop too.  An interesting bit on duckweed can be found online at the windward website.  It is an off-grid community near Lyle, WA..  If you do a google search on" Windward, Lyle, WA., duckweed" you can find the site and the info posted there.. 

    Two winters ago I did grow some duckweed indoors for a few months to feed crawdads, so I know it is not too difficult to do.  As soon as it warms up a bit more here, we are going to go full bore on  large-crop, with the idea of drying and storing it for over-winter natural feed (for fish and farm fowl).  I am sure you will have great success with this too!

Update on biomass project:  Ordered steam engine, should have it in a couple of months.  We will then reverse engineer and start building our own.  Boiler is in the design stages, should start fabrication in the next few weeks.

Hi everyone,

I found an interesting report on Duckweed.  It has a crude protein content almost equal to soy, it can double its mass in 24 hours (during peak growth), and it can be dried and pelletized for easy storage during the winter months.  I am going to raise a bunch this summer and see what quantities can be produced.

Just finished another greenhouse for a customer Sunday.  It turned out nicely. Pictures are the ones I just posted.    I am going to be back on my greenhouse soon.  I have found some more recycled sliding glass door panels.  I think there will be enough to completely cover the greenhouse in glass.

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.
