I found out about Metro transit saving the glass panels out of the bus stations when they replaced them due to grafitti and such. I called the maintenance yard in Tukwilla and made an appointment to pick up some of the panels. They are kinda heavy, half inch thick double pane safety glass. Really perfect for this. They have a design etched into them that looks like waves and sails, perfect for a greenhouse on an Island. I was stoked. We were able to find enough of the patterned glass for half of the wall panels, and we got un-patterned glass for the others. There were a lot of the panels that they could not give away, because the artist had a copyright on or some kind of agreement with them. But there was a lot of panels there that certainly would useful for projects like this.
Since I did not get any pictures of building the glass walls, I will try to explain it here. I took the studs and cut dados into the sides about 3/8 of an inch from the outside edge. Then I put plywood panels in the bottom and another short 2x4 (with a dado top and bottom) between the plywood and the glass above. I did the roof different, because the side walls were really tough to get together. I cut rabbets in the rafters so I could drop in the panels after the framing was done. Then I made strips (kinda like lath) to nail onto the top of the rafters to cover the edge of the glass and retain it. I just ran the shingles down over the top edge of the glass, and caulked it all up.
With all the other work we had to do around the place this project kind of took a back seat and I worked on it when the other projects were in limbo or while we were in between other things. The glass wall was facing the south and slightly east. It got the most sun we could get in the winter. During the summer we had to keep the door open a bit, (mostly because I didn’t fix the vents at the top which would open and close at one time).
I re-purposed my nice solid pine computer desk I had built years ago to use as a work table, and shelves for pots and plants. Made for a very nice potting table! Lots of polyurethane, lol. I was going to build tip out bins for potting soil and such to go under the work surface as well as drawers for stuff, but never had time before we sold the place and moved. I was looking for a cheap fridge for forcing bulbs and such that I was going to put in there to the left when you open the door, and was planning to put in a fan up by the vents and maybe a ceiling fan for the main area.
I put gutters on it and had a couple barrels that I welded up bases for to raise them, I was going to run a hose into the green house to use the water for the plants in there. I was thinking a system where a pvc pipe with small hoses (like a drip irrigation system) and a way to clip them up high to stop the water instead of a bunch of valves.
