Make a small green house for starting seeds earlier to extend the growing season!
The window will help trap heat inside the box so that it will warm up and you can plant seeds a little earlier. Basically, it works like a mini-green house.
I built this using an old window and some scrap wood that was going to be thrown out. The most important thing to have is the window or a piece of acrylic, you can pretty much build it around this then.
First step is to cut the wood. You want to build a box with a slanted top. I didn't put a bottom on this because i didn't want to worry about drainage.
Step two: put it together! I used some hinges to attach the window to the box with some hinges.
Done! I put mine so it would face the south and get as much sun as possible. Now you just need to put some pots inside, plant seeds, and water regularly!
