Make your own greenhouse using recycled plastic bottles
Why not make your own greenhouse using recycled plastic bottles. First you need to build a timber frame to the size of the greenhouse you desire, do not forget that you will need to make a frame for a door!
Then collect lots and lots of plastic bottles. 2L bottles are ideal and you will need to use bottles that have straight sides, shaped bottles will not work for this. Whichever size you choose don’t forget that all your bottles will need to be of the same size.
My greenhouse took approximately 1,500 bottles to make) Simply cut off the bottom of each bottle and then thread them onto metal rods, you will need to make sure they are all threaded on in the same direction so that the top of each bottle fits snug into the underside of next bottle. Next fix metal rods (top and bottom) to framework, butting up each column of bottles to the next until all walls and the door are created. The use of a few coloured plastic bottles above the door will give an interesting stained glass effect!
