Get a pvc pipe with rubber rings on both ends to make it waterproof. Dig a hole in a bush or somewhere similar no one will go. A quick hole, you want to be in and out so nobody sees you through a window and so you have quick access. or bag it a whole bunch of times and bury it.:lol:
Will filtering through water work or will it be too slow and end up overheating the box? I am going to have one plant inside an air tight 5 foot tall box and I was hoping to filter the heat and odour through a pipe into a bucket of water. The pipe will have a bend so the water doesnt fall...
