This is the first of several entries that will share the same name. I am going to document my efforts to build and run a successful aquaponics system in my greenhouse. To get started, let me explain the greenhouse. It is small. Just 8' by 6 '. I am able to use about 3/4 of it because I need to save the rest of the area for my wife to sprout small garden starts in the springtime. Right now, the rest of the small greenhouse is a disaster area. We use it to store a few of the garden tools and it also has a bunch of my beehive equipment. I have two beehives and so I store my smoker and a few other things in the greenhouse. Not that any of this is a particularly big deal, it is just something to be aware of.
Next, the weather. The weather here gets to be about 95 degrees and spikes into the mid 100's during July. Nights drop down to the low 80's. This should be okay for the fish. That is what I am worried about for the summer months. Will it be too hot for the fish. I am going to start with some small goldfish. Once I can get the system running decent, I will add a Koi or two. With the plan of raising them until they are big and then selling them as ornamental fish. If it gets too hot, I will install a small swamp cooler in the greenhouse. This should get it cool enough. Our average humidity here is around 6%--so swamp coolers work pretty good. In fact, about half the houses in this area use swamp coolers instead of central air.
Then, as winter approaches, I am going to research how to keep the greenhouse warm enough. I think there are some small propane heaters that can be regulated with temperature controls. If I have done my math right, it shouldn't cost more than about $20.00 a month to run in the winter. Not bad--if I can produce what I think I can produce with the system.
For this project, I am going to put occasional entries here on the blog. The whole point of this exercise is to find a way to become self sufficient. If the small system is successful, I will look at doing some larger systems. From my reading and research, it seems that for every square foot of garden area (area where you actually can grow vegetables) you can produce about 6-10 lbs of vegetables per year and about 2-3 lbs of fish per year. So in my greenhouse, I am going to start with 16 square feet of area and see if I can produce close to these numbers. Don't worry, I won't be eating the goldfish. I just want to start with them because they are fairly hardy--that way I am not killing off whole bunches of tilapia getting the system dialed in. I should be able to produce about 130 lbs of vegetables through the first year. If I can do that, make it through the winter and all, I am going to get going on a bigger system next spring.
