Tom's Greenhouse What is done so far and material list
The Greenhouse was started by digging a pit 14' wide 26' long and 5' deep by hand.
Next
the footings around the bottom of the pit were pored 12" thick 30"
wide with 4 - 1/2" rebar.
Then the walls were laid up with 8x8x16" block with a bond beam every other
cores and vertical rebar 4' on center .
Then the wall were filled with concrete.
Next the footings the fish tank were pored 12" thick 24" wide with 3 1/2' rebar. Then the floor for the fish tank was pored 6" thick. Then 2" ridge insulation was glued to the outside walls and the walls were laid up with 8x8x16" block with a bond beam every cores and vertical rebar 4' on center . and the walls filled with concrete.
Next a footing was pored down the center from east to west 30" wide 12' deep with 4 - 1/2' rebar. A second wall was laid up on the north side one block lower than the house floor. then a second wall was laid up on the north wall 2 blocks lower than the house floor.
Then four 16"x16" pillars were laid up on the evenly spaced on the center footing in such a way that the north side is the same height as the north inner wall and the south is the same height as the south inner wall.
Then the space between pillars was filled with 8x9x16" block laid on their side so that there would be holes for air to pass through. the top courses are bond beam block.
Next a footing for the space to hold the 3 - 55gsl. drums to be used as a filter and the air duct was pored and the block lied. The bottom course of the air duct was laid on its side. Next 8x8x16" block on their side 1" apart to the center of the first division and up the center east to west to act as an air duct to distribute the hot air to the rock bed the same was done to the other side of the center wall.
Next the pits were filled with abort 40 ton of fist size river rock to store heat and a 6" thick reinforced concrete floor was pored over the rock.
The frame of the green house was made of 2x6 redwood spaced 241/8" on center and covered with 8mm double wall polycarbonate from Sundance Supply.
The fish tank was coated with cloth and 6 coats of Elasto-seal rubber under coat from Snow roof. A beckett submersible pump with a fountain nozzle was installed to air ate the tank.
A
surreal cage fan and duct work was installed inside at the top of the greenhouse
in such away as to force the hot air into the rock bed under the floor to store
heat in the winter time and vent excess heat to the out side in the summer.
Another blower from a furnace was connected to the duct work in the house
with two thermostats on in the house set at 70 degrees and one in the greenhouse
set at 85 degreed so that if the house needs heat and the greenhouse has
it the blower will come one and heat the house.
The house also has a gas furnace with the thermostat set at 65 degrees so if the house needs heat and the greenhouse doesn't have any to spare the furnace will take over. Its the middle of December and the furnace has not come on yet.
Next I built 3 growing beds 4'x8' with side made out of 2x10" and a bottom of 3/4" cdx plywood and coated them with cloth and6 coats of Elasto-seal.

Around
the edges of the greenhouse and up the 10' back wall I will use a Hydroponics
system from.

The Lumber, blocks
mortar, and
Elasto-seal came from Home depot

The
original idea came from

So far I have found two places that use a system like mine.
