Step 4Mounting of the glass + tilting towards sun
iImage Information

Place the glass on the bottomless box, making sure the small pieces hold it in place firmly. Tilt the box somewhat to the prevailent sun-side (located in the south for northern temperate countries). In our set-up, we don't cut the sides of the box, but instead create a slope with dirt in the soil to tilt the greenhouse. However, if you truly want to, you may cut the sides so that the box is always tilted, even when placed on a flat underground. Depending on the location where the box is placed (shade or plain sun), type of glass used, types of seed to be grown, watering frequency, soil type, and other factors, more or less tilt may be applied. Generally however, only a little bit of tilt is more then plenty (using a little tilt also decreases the chance of the glass falling off accidentally).
