Rockwool

Rockwool is probably the most common growing medium used in the technique of hydroponics systems. You might be asking yourself, “What is rock wool?” But first, if you are not too familiar with hydroponics gardening, here’s some information that may be useful to you.

Hydroponics is one of the techniques used in growing plants. Instead of using soil, hydroponics makes use of other lighter mediums such as rockwool. It was around the seventeenth century that researchers found other alternatives to soil. In fact, hydroponics was already in use during the times of the Babylonians and Aztecs. However, it was only a few centuries ago that they learned that soil was not at all important for the growth of plants. Soil only helps reserve the water and nutrients needed by the plants. That is why researchers searched for other medium like rockwool to replace soil and avoid the pesticides and soil-borne diseases that are caused by it.

Now that you are aware what hydroponics is, you may go on to learn about rock wool. There are different types of hydroponics growing media, and each of them functions to help your plants absorb nutrients and water, and they all have their advantages and disadvantages. Rockwool is ideal for starting cuttings and seedlings, and it comes in different forms. There are rockwool cubes which are great for transferring and growing seedlings as well as the cuttings. At the same time, you can also use rockwool slabs or granulated rockwool which are alternatives to the rockwool cubes. There are also different brands of rockwool plant cubes available in the market. You can search online for these brands and try to compare which one is best suited for your garden. The Grodans rockwool cubes are one of the most popular brands being used by growers.
