I'm gonna check that out. You did your set up nice. I have acces to these blue Water Drums. My buddy owns a Pump and Drilling Company and they use tem for something. Anyways I'm building my smoker out of 2 of them soon. Small one for the fire box and the other the cooking racks. One is about 33 gal I think he said and the other is 80 gal. I've thought of trying rack aquaponics systems with these barrels. I'm not a huge fan of the taste of tilapia though so was considering Catfish and Brim. Have any experience with these fish?
Catfish should be okay, bream might not be able to take the heat. One of the fish I would like to try raising in the aquaponics tanks is yellow perch, but they have the same problem, they can take the cold, but I'm not sure that our summertime temps go too high for them. Be very careful, though, using any type of game fish, you might be required to get a permit for them.
Another thing you need to be careful of, is what was in those drums? You can wash them until your fingers bleed, and still have chemicals leach out and kill your fish and poison your plants. You even have to be careful with IBC's for the same reason. I get my IBC's from EcoGrow in Tucson, they only buy food grade IBC's from dairies, that were only used to ship milk.
Another thing I forgot to mention about all those greenhouse pics is that all that stuff was planted in mid-March. Using an aquaponics system does give your plants accelerated growth and health.
@lilchikn, you were asking if a greenhouse is required I highly recommend one, and here are a couple more reasons, wind, and early plant starting. The wind issue is pretty self explanatory. The other reason is that we actually have a pretty short growing season in Tucson, before it becomes too hot. You want to start your plants early, so you can harvest them early. Once it gets to about 90 degrees and above, many plant pollens become sterile, and won't set fruit.
One drawback to an aquaponics system that isn't mentioned much is that you have to keep plants in them all the time. The plants absorb nitrates from the water which helps them grow strong and fast.
The growbeds are the biofilter. If you don't have enough plants in the grow beds (or too many fish in the tanks), nitrate levels will rise enough to kill the fish. I need to do some more research and figure out what I'm going to keep in there over the summer.
P.S. There are some good reasons why you might not be too fond of the taste of tilapia, if you knew how they were raised. Try some aquaponic raised tilapia, and you'd probably change your mind.
