Is growing in Coco hydroponics?

When properly treated coco can be a very good media for growing hydroponic crops. The bigger aeration, biodegradability and fibrous structure makes it better for root growth than most peat moss sources and yields for several plants are often bigger or just as good in coco when compared with peat moss.

What is the best grow medium for ebb and flow?

The system is great for using anything from Rockwool to hydroton. One of my favorite growing media to use in an Ebb & Flow system is hydroton. Hydroton is expanded clay pellets that work as an anchor for the plants roots. It stabilizes the plant and gives the roots a media they can grow easily through.

Can you use peat moss in hydroponics?

Peat moss is often used for seedling starting, in potting mixes, and even as a primary hydroponic or aquaponic media. Peat is not appropriate for all hydroponic systems, however. Once it starts to decompose, it compresses around the roots, which are choked out in the anaerobic root zone.

Do you need soil for hydroponics?

Using a growing method called "hydroponics," you can grow plants in a watery solution of mineral nutrients instead of soil. If you can add these necessary mineral nutrients into a plant's water supply, you no longer need soil for the plant to grow. Just about any plant can be grown with hydroponics.

What plants need perlite?

The substrate creates air pores and even holds oxygen that the plant roots can use, making it a wonderful addition to any substrate that may compact. It can also be used as a primary medium; many Bato bucket (Dutch bucket) growers use perlite as the primary medium for growing tomatoes.

Does perlite decompose?

Perlite does not furnish any nutrients to the plants. Its particles do not decompose with time, so perlite is a better choice than vermiculite for plants that will be repotted infrequently.
