Grodan Rockwool

Rockwool is volcanic rock that has been superheated to a molten state, then spun into fibers. The fibers are then compressed into cubes or slabs, or shredded into a granulated form. Rockwool offers an excellent balance of air and water for your plants' roots.

Hydroton Grow Rocks

Hydroton grow rocks are made of clay that is heated in a furnace until it expands and fills with air. Grow rocks are lightweight, porous, and reusable. Since they are made just for horticultural use, they require no pretreatment and will not react with nutrient solutions.

• Dyna-Rok Silica Stone (Medium Grade) 40 liter (10 gallon), $43.99

Perlite

Perlite is puffed sand and can be used as a hydroponic medium for small, lightweight crops such as lettuce. Perlite is often added to a soil mix to improve drainage and aeration.

• Chunky Perlite 4.0 cubic ft (26 gallons), $32.99   IN-STORE ONLY

Vermiculite

Vermiculite is puffed mica. Each piece can hold many times its own weight in water, so this medium is often used to increase moisture retention in a soil mix. Vermiculite can be used as a medium for cuttings, but is not usually used by itself as a hydroponic medium.

• Vermiculite 0.75 cubic ft (5 gallons), $7.99
• Vermiculite 3.0 cubic ft (20 gallons), $21.99
• Vermiculite 6.0 cubic ft (40 gallons), $37.99   IN-STORE ONLY

Coconut Fiber

Coconut fiber is a fairly new growth medium, but its popularity is growing quickly because of its impressive results and versatility. The fiber holds lots of moisture while also permitting excellent aeration and drainage. The coconut's natural rooting hormones promote excellent root development—a wonderful medium for cuttings! Coconut fiber can be used by itself, or blended with some combination of soil, perlite and/or vermiculite. In hydroponic systems, the fiber is usually blended with grow rocks. Coconut fiber shares similar properties with peat moss, but the coconut fiber (a by-product of coconut processing) is a totally renewable resource! Sold as a compressed brick or larger block—soak in water to expand compressed coconut into loose fiber medium. Individual bricks make about 2 gallons of medium, while the larger block makes 18-21 gallons.

• Coconut Fiber 1 brick, $2.49
