Hey Another Iowa Dude!!!

Hey Man our electricity is only .08 cents per KW. Crazy right

I am not quite sure where you got the electrical usage estimates. Some pumps use very small amounts of power 200 watts max, you can get a couple of 200 watt Fluorescent ballasts, 20,000 to 40,000 lumens depending on the brand. That is less than 20 kWh per day or 1.60 per day = $584 per year max.

The food will cost you, to me, you can get a ton of benefit by starting your out door plants indoors using aquaponics. This would payfor itself if you would utilize outdoor planting in the good parts of the year.

Black soldier flies, worms, duckweed would cut your costs a ton.

I would go with a intex above ground pool, 8' x 30" deep for only 50 bones. Pump, Growbeds, lights, You could get all that done for less than $2000. I made a 50 gallon system for about $300, but that does not provide much food. I would say you need at least 300 gallons to make it worthwhile.

If you build your own tanks and beds you may be able to save some cash too.
