Expanded Clay pebbles are used in hydroponics as a medium to support the plant. They are chemically inert, do not affect pH and provide excellent drainage. They are made from a special type of clay, which is heated to a high temperature causing it to pop like popcorn. Because the pebbles drain freely and don't hold excessive water, they provide good oxygen levels around the root zone and are particularly suitable for flood and drain systems. In drip irrigation the pellets can be mixed with a medium with better capillary action so the feed is dissipated broadly through to prevent salt build-up.

Specifically for hydroponic cultivation.

Premium ready to use potting soil mix that is lightly pre fertilised. This mix contains a secret ingredient which under test has performed extremely well. With this mix an ideal air and water ratio is achieved with a larger water retention capacity than general soil mixes but still high level of aeration. This means that the absorbed water and nutrient elements are released gradually. These factors have an extremely positive effect on germination and also encourage faster and finer rooting, enabling the plants to perform to their optimum potential later in life.

Sure to grow™ touts itself as a “revolutionary new plant growth medium” and a 21st century alternative to rockwool, perlite, and coco coir for hydroponic growers. It’s made from recycled plastic bottles – but feels and looks more like cotton wool! it’s now available in the uk so we asked some urban gardeners in the us and canada for some practical tips and tried to find out if this latest growth media to come across the atlantic is a gimmick or a godsend!

Sure To Growª (STG) is super lightweight, easy-to-handle stuff that boasts all the qualities you would expect from a modern growth media. It’s easily wettable and highly aerated - we’ve heard this kind of stuff before. It’s also pH neutral so no presoaking is required. You can store it indefinitely and it’s not irritating to skin. However perhaps the most interesting thing to note about STG is that it is a non-wicking growth media. This means that it has no “capillary action“. STG does not “suck up” and absorb nutrient solution into itself in the conventional way like rockwool and coco coir, for instance. Instead it simply holds moisture within itself in a sort of “nutrient suspension’. The makers of STG claim that plants grown in STG don’t have to work as hard to get at the moisture and so don’t have to spend as much energy on feeding.
