Cutting Glass Bottles

Thought I would post this instructable I came across for those looking to use an alternative to plastic. Rather then create a cup, you would use the other end of the bottle for the farm.

Sounds interesting, but how would you work out the drainage?
You use the side with the neck of the bottle instead of the ‘cup’ end.
