Its the ultimate recycling drive! Reusing 2 litre bottles to create a greenhouse. It seems interesting however from my knowledge of greenhouses that are used in the Caribbean there is an issue of heat. If you look at the video, the plastic bottle greenhouse that was created is completely sealed. Therefore if it is to be used in the Caribbean region it must be redesigned to include mesh nets which allow air to pass through the greenhouse will still allowing the construct to be efficient. What do you think?
