solar hothouse - buy polycarbonate panels
Concept: as a young boy, I 've always enjoyed going through my grandfather's huge greenhouse and admiring all the cool and exotic plants, and I 've wanted one ever since.
I was lucky to be able to find free or free materials such as shower doors, storm windows and doors due to limited budget
Vincent de Paul or the Habitat store and craigslist.
Cedar planks and fir columns were crushed from the unexpected tree in our backyard forest.
My neighbor offered to chop them up for free with his saw mill.
The arc-shaped aluminum pillar of the ceiling was picked up from an ancient antenna.
The exhaust fan of a crashed Honda car was found in a local wreckage yard, as was the battery running the exhaust fan.
In the items that I have to buy directly (
It is solar charger, double wall grease board, passive exhaust actuator, some concrete, anchor bolts and nuts and screws.
I did not press-to draw a detailed plan
Se, but the layout of the shower door was drawn to get some size.
Since I found eight doors, I made the whole length to hold the collective width of them.
The evolution of height is roughly the same.
I know I want a solid wall about 3 feet thick at the bottom, then add the height of the shower door, then add another part of the cedar board plus the height of the roof structure, which makes the overall height appropriate.
The same is true of my design process.
So this project is organic to some extent.
Of course, these sizes can be adjusted according to your material and design.
Like most of these structures, the foundation is important.
Light structures like this are easily damaged by strong winds.
First, level the area.
Then set the sand and level of Layer 1 (
A large landscape rake is perfect for this).
You can then lay a layer of gravel or bark, or whatever you like to walk.
All this can be compressed if you want.
I decided to use the galvanized column anchor set in the concrete.
Layout location for your post. I can't over-
Emphasize the accuracy of the layout position.
If you don't put things in a row, in a row.
Since my structure is 20 feet long, I want to put a pillar in the middle, so I put three on each side.
Use string lines, tape measure, and level to ensure the location of the post.
Dig about 1/2 holes.
About 9 deep-10" diameter.
You need a specific table to include concrete that flows on the ground, like 2-3".
If you use cedar boards like I do, you don't want them to be just on the ground.
You can buy cardboard tubes in concrete shape, but I just nailed some scrap wood together.
Mix the concrete and pour it into one hole at a time.
When checking the height and position with a level ruler, tape measure and chord line, shuffle the column anchor into concrete.
Once you get it right, you need to support it or block it in place with waste wood or bricks etc.
Then check again, adjust as required, and repeat each post.
Let the concrete dry for about three days without interference.
Then you can start fixing the pillars.
Once the concrete is cured and the post is bolted in place, you can start to nail or screw the board on the wall.
I love the screw because it's safer but also more expensive, it's your choice.
This is a very simple process.
Fix the boards in place, check if their levels and ends are in the position you want, and fix them on the pillars.
If you want to be more fancy and have a tighter connection, you can grind an overlapping Rabbe joint or tongue and groove on the edge of the board.
Or you can overlap the edges.
It may be a good idea in a cold climate.
Build your wall to where you want to set up the window and keep checking the level.
And the position is still vertical.
Before you open a few boards, you may have to support the pillars to keep them vertical.
Depending on the location of your top wall panel and the size of the shower door, add a thick piece of wood to the top of the vertical pillar.
I call it The Window header and set up a widow now (shower doors)
At the top of the last wall panel, fix your fixing plate to the top edge of it and screw it to the window board.
I used a board on which I cut the thickness of the window, about inches high, so it overlaps the top of the window to keep it in place.
From there, you can push the remaining windows to the relief and set the bottom on the wall panel at the top.
Once the window is in place, you can start adding vertical bars like 1 "x 2" s to protect the sides of the window.
These vertical bars should be the full length of the wall and screwed to all the boards.
Cedar weather is fine, but for increased protection, it will be a good time to paint all exposed wood with some kind of preservative.
Taking into account the additional longevity provided for all your efforts, this is a simple and economical step.
The roof structure may be the most challenging for several reasons.
First of all, I rescued these cool curved aluminum pillars from the old 10' antenna I really wanted to use.
But I know I can't build it on a greenhouse. At 6'-6" and 245lbs.
I can imagine a terrible YouTube scene.
And, how can I get to the edge of Juhuasuan and screw them down?
So it has to be built on the ground and lifted in place.
I chose a clean place in the driveway.
I arranged the pillar position on a 20-foot-long 1 "x 1" square aluminum tube (
Gifts from artist friends)
I pieced them together with simple metal brackets and screwed them in place.
To secure the polycarbonate panel in place, I used the 1/2 "x2" cedar strip, I heated it in the shower for a while and then bent it with a simple fixture to form a curve, then clip on the pillar to dry.
I then cover the top of the pillar with foam tape to narrow any gap and place the panel on it, screw the cedar strips on it and screw it into the pillar.
Once done, I found that the structure is still too flexible to move, so I added another aluminum square tube to the outer edge.
Make it more Ridge.
There are four people at this point who can lift it up with a thrust stick, but I can't find the other three so I have to improvise.
I fixed an 18 long wooden beam on the bucket of the tractor and pushed it to the end of the roof structure.
At the age of 20, it was very rough, but after a little careful technique (
When did the steering on the tractor go out! )
I can install it on the 8' wall.
I have previously set the window frame for the curved pillar so that the polygon panel can be set on the corner of the window frame and close the connection.
With a little encouragement, everything started.
I then screw struts into the title through the cedar strip.
This is where previous careful attention to the measurement, square and level of base, post and all other content really pays off.
This part is optional, but I already have this solar panel to charge the rain pump in the garden.
The panel was about 25' away from me, so I dug a ditch to extend the wearable cable from the charger into the hot house.
It is connected to a 12 v car battery that is connected to the re-
Car radiator (exhaust)fan.
There is a limit switch in the circuit that is activated when the automatic hot vent opens the vent window to a point and the fan is turned on.
This activation point is adjustable so that the fan does not turn on until the temperature is high enough to really need it, depending on how open the vent is.
The battery will also be stereo for small 12 v cars (
Plants that love music
Maybe some LED party lights.

Purpose, but I have seen greenhouse kits of similar size, 10 times what I have invested in $600.
