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.

Lessons learned about nutrients and pest control

Well, it's been a few weeks since my last post. I'm sorry to say that I did not do my due diligence in researching the addition of nutrients to the growbeds in conjunction with the use of organic home made pest control measures. Due to some iron deficiencies in several of my plants, I decided to order some chelated iron to add to the fish tanks and to spray on the plants. I also, experienced some issues with red spider mites on a few of my plants, some on my Cilantro, and Stevia. After mixing up a home made remedy of garlic pepper tea, I decided to attack the red spider mites with a spray bottle of my home made concoction. This appeared to work, so I decided to spray all of my plants...no big deal or so I thought until I sprayed them afterwards with the iron chelate, which was a little to strong. As you can imagine the garlic pepper tea opened the pores in the plants leaves/stems and the iron chelate, being a little too strong, did the rest. By the next morning I had tons of black leaves on most of my plants and within a few days many had died and / or the leaves were severely burned. I am glad to say those plants left have recovered fully, and are growing once again. I even have a few new tomatoes on my plants.  I also had to pick a few cutter type worms from some of my swiss chard, so I have ordered some organic BT and Neem oil spray to treat the pest in the future.This will also help with any fungal problems I might encounter in the future. Lesson learned, follow the instructions to the letter on the label, or from the source of the information. A setback...yes, but not the end of the world.

Here are a few pics of the disaster.
