Rockwool is a horticultural growing media made from the natural ingredients Basalt rock and Chalk. These are then melted at 1600° C into a lava which is blown into a large spinning chamber, which pulls the lava into fibers like "cotton candy." 

 

Pre-soak

Ideally, rockwool should be immersed in a nutrient solution adjusted to pH 5.5 until all the rising bubbles are gone. Let the rockwool drain freely until water is no longer running out of it. Air will re-enter the largest pores, achieving the perfect balance between air and water in the medium. No squeezing or wringing is required.

 

Always fertilize your rockwool

Rockwool does not lock out any fertilizer. All the nutrients present in the block will be in the solution available to the plant or ready to drain out the bottom. This means whatever nutrients you use will have an immediate effect on the plant, and any feeding mistake can be immediately corrected, allowing you to optimize your fertilizer use.

If you irrigate with just water, the fertilizer concentration in the block will drop and may cause a slight shock to the plant. Rockwool has a tremendous capacity to retain water, so it is better to irrigate less often with a well-balanced nutrient mix than to water more frequently without the nutrients.

 

Allow for Sufficient Run-off

Plants always take up water at a higher rate than nutrients, so expect some increase in the concentration of fertilizer salts inside the medium between waterings. Furthermore, not all nutrients are taken up by the plant at the same rate, which creates nutrient imbalances and modifies the pH over time.

When the root zone is irrigated again, the water will push those nutrients down and replace them with the fresh nutrients it carries. If you never allow the substrate to drain sufficiently, the nutrients that were not consumed will accumulate in the medium, which may be unhealthy for your plants.

Allow 15-30% of the volume of liquid going in to drain out the bottom of the medium to maintain optimal nutritional conditions in the root zone. Rockwool is the fastest and easiest substrate for this, but this principle applies to all media.
