Do you remember the Handmade Bottle Planter I showed you some time ago? It was a little homemade self-watering system for your plants. But today I have something much bigger for all happy owners of greenhouses and all who love gardening.

Eco-friendly ideas are brilliant for everyone who wants to save time and money. Thanks to ‘Engineering for Change’ you have a chance to know one of those. Using 50-gallon drums and pipes system you can build thriving vertical farm for vegetables and fish. A vertical aquaponic system grows vegetables without soil in columns above a fish tank. It is a water-efficient and space-saving way to garden and raise fish. You can take care about the vegetables and your fishes at the same time. You can use this super-effective idea in a small yard, a corner in a community garden or an unused space in your greenhouse.

Do you have your very own aquaponic system in your greenhouse? Let us know in comments below or talk about it on our fan page!
