Aquaponics Greenhouse Design

Aquaponics coming to Bloomington, Indiana!  Here is a design rendering for the project.  We are currently finishing the foundation work on the 24' x 48' greenhouse, and the trusses are soon to arrive.  You can see the 900 gallon tanks in the back, and each is connected to six 4' x 8' hydroponic beds which will host a variety of greens.  Each row of six beds is connected to one tank, constituting a "node".  I haven't shown any plumbing to make a clearer image.  Each tank will grow about 1000 lbs of tilapia, ready for harvest after 7 - 9 months.  The fish effluent from the tanks will be piped to each bed, where bacteria in the gravel beds digests and oxygenates the ammonia and nitrite to nitrates, which is taken up by the plant ribosomes.  The water drains back to the tanks!  I'll be documenting the process with videos and images, so stay tuned!

Installing Level Cabinets in an Older House

Last weekend I helped our friends Jason and Jen over at Humphrey-House who are nearly finished enlarging and remodeling (and "greening") their kitchen.   I brought over some color swatches and helped them pick out some great colors.  Then, my years as a builder/remodeler came in handy as I showed them how to install level cabinets in an older house .

Since the floors of older houses are so NOT level, a clear tube with water is the answer.
