What is expanded shale?

Expanded Shale is a long lasting soil amendment that is made from clay or shale heated in a rotary kiln until it becomes a light, porous ceramic aggregate. Expanded shale improves soil aeration and drainage; and remains inert in the soil creating long term value.

Is expanded shale good for succulents?

Expanded shale is my drainage additive of choice. Succulents in general require really good drainage to keep water from sitting on their roots. You don't have to use expanded shale, many succulent gardeners use sand, crushed granite, perlite, or other materials to increase drainage of their soil.

What is the best growing medium for aquaponics?

Lava rocks have been used as a hydroponics and aquaponics growing medium for decades. They are lightweight and porous and provide beneficial drainage, aeration, water retention, and even trace elements to the system. And, like any good growing medium, lava rocks are pH-neutral.

Can you use lava rock for hydroponics?

Because this rock is porous, it can serve as a good grow medium. ... Now your lava rock is ready to be placed inside the plastic pint containers that you use to house plant roots, which will grow down into the lava rock to get access to nutrient-rich water.

What is shale good for?

Shale has many commercial uses. It is a source material in the ceramics industry to make brick, tile, and pottery. Shale used to make pottery and building materials requires little processing besides crushing and mixing with water. ... The petroleum industry uses fracking to extract oil and natural gas from oil shale.

Is shale good for soil?

Adding it to heavy clay soil lightens and aerates the soil. Expanded shale also holds 40% of its weight in water, allowing for better water retention around plants. Unlike organic amendments, expanded shale doesn't break down so soil stays loose and friable for years.

Which is better hydroponics or aquaponics?

Plants. Hydroponics growing systems can be used for plants with high nutrient needs because the nutrient solution can be adapted to meet plant needs; aquaponics systems typically work best to support plants that have lower nutrient needs such as lettuce, other leafy greens, and herbs.

Do plants grow faster in aquaponics?

Plus, aquaponics systems are beneficial because they don't harbor soil pests, therefore no pesticides are necessary. Plants Grow Faster – Because plants have access to nutrients 24 hours a day, they grow faster. For example, the aquaponic system speeds up the growth of lettuce from two months to one month.

How long do you need to wait before planting in aquaponics?

How long you have to wait before adding fish to an aquaponics system is until your system has cycled. In colder climates your aquaponics system can take between eight to ten weeks to cycle. Whereas in warmer climates an aquaponics system can cycle within four weeks.
