Aquaponics combines two growing methods, aquaculture and hydroponics, to create a self-contained, well-balanced ecosystem. Fish are fed and raised in a tank and as gravity pulls the wastewater through a hydroponic garden, bacteria feed on the waste, breaking it down into essential nutrients for the plants to grow. The system then returns the cleaned water back to the fish reservoir so the process can begin again.

In this episode, Charles Collins shares his backyard aquaponic and hydroponic gardens where he's able to grow tilapia, leafy greens, peppers, herbs and so much more, all in the suburban desert. Together we grow!

ABOUT PARAGRAPHIC

A story is more than a title. We are a small team of independent filmmakers focused on emerging interests. We love exploring the wide landscape of these enthusiast communities through personal stories from their most passionate creators. The underdog, the obsessed, the misunderstood, the ones who have committed everything to their craft. For them it's more than a hobby; it's a way of life.

From garage bakeries and gourmet mushrooms to vertical farming and worm composting, these stories will elevate your understanding and deepen your appreciation.

Look beyond the impression.

In this 17 minute film on plant and seed propagation, Tholina shares her lifelong knowledge and skills on how to set up an efficient nursery. She tells us about her techniques for seed selection, storage and propagation. And shows us some tricks on taking vegetative cuttings for vegetables, herbs and other hard wood species, as well as the different soil preparations and watering approaches to be considered – all using what we have available to us.

What do trees talk about? In the Douglas fir forests of Canada, see how trees “talk” to each other by forming underground symbiotic relationships—called mycorrhizae—with fungi to relay stress signals and share resources with one another.
