Here is a simple project for growing tomatoes using a 2-litre bottle.
What you will need:
-2 litre bottle
-spray paint (krylon plastic-ready)
Take a 2-litre bottle and cut the bottom off about 2 inches from the bottom.With the remaining top paint the outside of the bottle with spray paint. Allow to dry.
Remove the bottle cap. Gently work a tomato seedling through the screw top opening. Fill inside of bottle with potting soil. Reverse the bottle base you previously cut off into the opening of the bottle. Heat wire over a candle and poke holes in the bottom of the base. With the same wire melt holes into the side of the previously cut off base and the bottle wall. With the melted holes use wire to secure the base to the inside of the bottle. Wrapping wire through these parts, make a section wire to allow you to hang the bottle.
This project allows you to plant a tomato plant upside down. The cut dish is a reservoir for watering the plant. Spraying the outside of the bottle helps reduce the amount of sunlight that will penetrate to the roots.Hanging tomato plants is an excellent way to grow tomatoes for those with reduce gardening space. Additionally it allows plants to grow off the ground where insects and rodents may pose problems.
