| Hydroton Clay Growing Pebbles |
Hydroton clay pebbles (or ''rocks'') are made from pH neutral clay. Their air to moisture ratio makes them ideal for hydroponics. They can be used to fill plastic net cups in aeroponic and NFT (Nutrient Film Technique) systems, as a medium for drip irrigation systems, or as a medium for container gardening. Hydroton is an expanded clay medium manufactured in Germany and is well suited for growing larger plants like tomatoes and peppers. It holds water extremely well and offers good capillary action. It is reusable, clean, and odorless. The 10 liter bag will fill approximately 24x 3'', 21x 3.75", 10x 5", 8x 5.5'', or 4 - 8'' net pots. The 50 liter bag will fill about 4x 5gal containers. Perfect for passive, wick, and subirrigation use, individual hydroculture pots or hydroponic systems. Reuse over and over by rinsing out roots then sterilizing in a very mild bleach solution (about 1/2 cup per gallon of water). Rinse well before using. |
Higromite™ is the only growing medium of its kind in the world. Higromite™ is mined from volcanic deposits colonized by protozoa in freshwater lakes millions of years ago. These unique mineral deposits offer a broad range of trace elements that support microbial activity which enhances root growth, plant vigor and crop yield. Higromite™ provides several advantages over expanded clay pebbles, coco, and rock wool. It’s high in silica, pH neutral, and has the best moisture retention & release on the market today. Completely reusable, the varied shapes of the rocks promote porosity, allowing more oxygen to reach the roots. |
| FoxFarm Big & Chunky Perlite |
FoxFarm Big & Chunky Perlite This oversized perlite allows for excellent aeration and drainage. The large, porous surface holds moisture well and improves nutrient uptake. Large size helps keep perlite in net cups. pH is neutral. |
Perlite Perlite is a light weight, white, expanded, closed-pore alumino-silicate mineral of volcanic origin which has become widely used in the horticultural industry as a component to peat-lite mixes. The ore is crushed and heated to approximately 1800°F (982°C) which causes the ore to expand. |
Perlite is now utilized extensively for its light weight, physical stability and ability to provide non-capillary pore space in a mix. Perlite has little waterholding capacity since the internal pore structure is closed. It has extremely low cation exchange capacity, no nutritive value of its own, and no notable influence on pH of mixes in which it is employed. |
