How To :
- Make a Greenhouse. You can make a greenhouse from any container you like, so long as light can penetrate its walls.
- use a pen-knife to cut around the middle, almost all the way through. The uncut half-inch or so will serve as a hinge.
- Next, punch out drainage holes in the bottom. A Phillips screwdriver, heated over a flame at the stove, will facilitate the hole-punching job. Punch out also a few holes along the top portion of the container. These extra holes increase air-ventilation.
- Select the Right Soil. It is essential to use a soil mix that drains well. Pour the soil, preferably to a depth of 3 to 4 inches, into the bottom half of your container. Then moisten the soil thoroughly and let it drain.
- Sow the Seeds . Sow your seeds on the soil surface, and then cover them with more soil, when necessary, to achieve the proper planting depth.
- Then replace the lid, and secure it with a strip of duct tape, as illustrated.
- Bring the Greenhouse Outdoors. Your greenhouse, once planted and labeled, is ready to brave the outdoor elements. Select a location that is safe from strong wind, but where sun, rain and snow will be freely admitted.
- At the first kiss of spring, but while nights are still freezing, seedlings will begin to emerge. Now is the time to check for water. Open the tops, and if the soil appears dry, moisten thoroughly but gently, so as not to disturb tender root systems. Then close the tops again.
- On warm, sunny days, I open the tops for hours at a time, and let the seedlings enjoy the fresh spring air. The tops, of course, are closed at dusk.
