I haven't started on mine besides build a few of the beams.
It will run east to west, the north side will be covered and insulated, i was going to put my fish tanks in the green house but I decided to add a hip roof off the north side to house them. it will cut my glazing costs.
making it gambrel style though.
making these
The big picture plan is that twin wall poly-carbonate as my glazing.
both on the inside and out side.
Should help a bunch to insulate the greenhouse, I'm also thinking it should help with the plants not getting sun burned. as the panels have 80% light transmission.
Going to have to settle for poly until i can raise the funds.
into these
basically 1x stock from pallets,milled straight and true, wide face to wide face, 3 deep,
nailed together.staggered so no breaks between pieces line up.
You can make beams as long as you like from what would other wise be useless wood.
they join with a plywood gusset at the joint to make the trusses.
Bit of work,but the only out of pocket is gas to pick them up and some electricity.
When I do pick them up it by the trailer load so the gas isn't to pricey.
still lot cheaper then having to buy it.
Wow I just relized how old this thread was... So Tiempo did you get one built?
