A Green Project Challenge

The intent of this project is to see if being more green is viable given the cost of materials vs. the Return On Investment (ROI) for operating my own greenhouse aquaponics/aeroponics system in our backyard. The challenge is whether I can design, build and operate an aquaponics/aeroponics based greenhouse system in a sustainable manner with a small carbon footprint while providing food for the table at a reasonable cost over conventional methods such as purchasing fish/vegetables at the local grocery. Join me on this journey of discovery while I forge a new chapter in my quest for a better tomorrow.

Insulation added to the Greenhouse

With the upcoming weather changes for fall/winter approaching, I decided to bite the bullet and put up some radiant type / bubble insulation with an R3.7 value. I placed all of this on Saturday last weekend and stapled it in place using a an Arrow T-50 stapler. I used approx. 8 - 2' x 25' rolls, and a single roll of 4'x25' for the IBC Fish Tanks. This material was placed along the end and side walls, and also along the roof trusses. This also provides extra reflective light back onto the plants for added growth.





We had a cold snap this morning which dropped the temp down to 52 degrees outside. With the insulation in place and the greenhouse closed up the temp stayed a balmy 74 degrees.
Not bad for this amount of insulation, of course winter has not set in yet, so for added protection I have purchased a small ceramic based heater which I will use to supplement the natural radiant heat of the greenhouse. I also have purchased a digital dual 500 watt Titanium aquarium heater unit which will be placed in the Fish Tanks to regulate the heat during the winter.


Next up, the building of an Aeroponics cloner/seedling starter system.
