If you’ve got a bunch of old windows sitting around, why not put them to work for you as a greenhouse?

Did the vinyl cover from that old carport finally rot off? Put the pipes to use to build a greenhouse instead.

  1. So many choices.
    Love the recycling ones the most and have already started collecting empty winebottles.
    I am thinking of angling a few of them (in the wall) in such a way that i could put soil in the bottle, have a few drainage holes in the cap and have a hanging plant grow from it.
    Thank you so much.
