After hammering out the dimensions and then the materials list. Deciding on what plants I'd like to grow and trying to source some major costs items I got lucky. I ran across a suite billboard cast off from a local company that would serve as the basis for my entire system for just $75. The only thing better than the cost was the subject matter I was so disappointed. NOT.

I also was able to connect to a local salvage company to get some 4' x 2' x 3" fluorescent lights for $5.00 per fixture. I got 12 of them. While these are the old T12 40 watt bulbs they are all in working order and the 8 watt difference over the new energy efficient t8's. Using the 10 cents per kilowatt I pay and the electricity cost calculator the difference is 0.01 per hour. Since a comparable t8 light would cost me about 120.00 it would take approximately 70 months for the cost savings to add up. In addition the salvaged t12 all came with 4 working bulbs. The added costs of new t8 bulbs would push that out significantly higher.

Having these two large costs out of the way I was hoping to have the system setup for under $600.
Spring Lake Trout Farm is the closest to my home and offers sterile Rainbow trout fingerlings for $0.25 per inch and delivery for $1.50 per mile. I was going to start with 50 fish which would put my stocking densities 1 fish per 7 gallons which is conservative but gives me plenty of error and grow room. Fish costs: $137 for 4" fingerlings

I wanted to grow my fish in totally cleaned and purified water, so I sourced a local RO bottling company and it was going to be about 30 cents a gallon to fill up my 55 gallon drums to then fill the tank, or fill up 5 gallons at a time for a cost of 25 cents a gallon from the local jug dispenser. The extra time and hassle seemed worth 5 cents. This would come to about $115.00

Next I jumped down to my local Home Depot and purchased
9: 4x4 posts
56: 2x4's
3: 2x8's
8 sheets of 15/32 OSB. I came to this as my design was going to have 12" spans at most, then I calculated the weight of water per square foot, added in the grow media and fish calculations and came to needing to support 170 pounds per square foot which at 12" spans 15/32 will support up to 390 (available from home depot's pro desk) so that seemed safe
1 large box of 2.5" treated deck screws
1 small box of 1.5" treated deck screws

for a cost of about $250

I also got lucky enough to pick up a temp and humidity sensor for half price on woot.com as well as a LeakFrog Leak Alarm at half price to help protect my basement in the event of a leak.
