If you have an older model greenhouse, you can purchase gutter end caps and elbows as retro-fit for your gutters. The newer models come with them, so you do not need to order them seperately.
Gutter end caps and elbows are used for capping off your gutter to collect rain water into a collection tank. Rubber tubing and tank are not supplied but can be purchased at most hardware stores. Elbow outside diameter (for hose connection) is 18mm.
