This  concept was made for a school garden , in order to attract student's interest to be occupied in the garden of their school .  It consists of three cylinders , in which the plants are growing. Inspired from the idea of the compost bin , each one of the cylinder is used as a compost cylinder at first.

The compost is collected from the students and is put into the cylinder. They leave it for 15 days and after that period ,the cylinder is ready to be planted , normally . During the period of the 15 days , the students can observe the differences that  are processed to the compost and how it ends up to be normal soil.

After that period , the students can plant normally .

Mostly the compost-cylinders can be used for flowers and decorative plants.
