The manufacturer has many years of experience developing Rock wool products in the Netherlands and is preferred by some of the largest industrial propagators in the world. The quality of their newest Rock wool cubes, plugs, and starter sheets is by far the best on the market with superb air to water ratio and a fiber structure that holds water longer and has less resistance for the roots to grow in, resulting in stronger roots. Rock wool also encourages faster initial rooting and its firmness is guaranteed. Cube measure 10 cm x 10 cm X 6.5 cm

Features:

It has to be stressed that only horticulturist rockwool can be used to grow anything since the rockwool you can buy in hardware stores, for example as insulation material, is treated with special chemicals and oils that will kill plants.
One of the best things about rockwool is that due to the fibrous texture it will hold plenty amounts of water and still more than enough air to prevent roots from rotting.
Rockwool will need no special care to sterilize it since it comes that way, will not attract 
many fungi that cause root rot and cause leaf fungus as well, it is light unwatered and will produce no mess indoors.

The nutrient solution

Rockwool contains no nutrients whatsoever. It is the task of the chili farmer to provide the plants with the needed nutrients in the solution in the needed pH range. Fertilizers have a set formula of main and secondary nutrients. 
Most important is the main nutrients formula which is noted in the NPK form which stands for nitrate, phosphorus and potassium (kalium). 
Good fertilizers also have a declaration of all needed secondary nutrients on them. From my past experience and the current grow in progress I swear by three part hydroponic fertilizers. They come in three different bottles containing different formulas each. Mostly two bottles refer to different grow stages and one contains micro or secondary nutrients. 
With those you will have control over the nutrients for the different phases the plants are in. Those are: Rooting, vegetative growth, flower production and fruit production. With chilies flower and fruit production overlap somewhat since even while fruits are already growing most plants will continue to produce new flowers during the season. In the rooting and flowering phase the needs of the plants for phosphorus rise, during vegetative growth the plants need more nitrate and potassium and during fruit production the focus lies on potassium with somewhat less nitrate to keep the leaves healthy.
