Plants grow very slowly when its cold.
A minute project to create a very small greenhouse with an 8 liter water fountain.
Step 1: The Top
What you need : a water fountain and a good knife.
Cut the cap, then the top
Step 2: Bottom and Finish
cut the bottom, put some soil , water and seeds.
Due to the shape, when the weather is cold the water condenses on the top part and get down to the the ground so it uses very little water : 2 cl a week.
