Hydroponic cultivation is an approach based on supplying nutrients directly to the roots of plants through an aqueous solution. Rockwool is an inert substrate that integrates perfectly into this system, as it does not interfere with the chemical composition of the nutrient solution.

A key aspect to obtain optimal performance from rockwool is its proper preparation. Before use, it should be soaked and rinsed to ensure it has a pH in the range of 5.5 to 5.8, which is essential for proper root development and nutrient absorption by the plants. This process ensures a neutral and favorable environment for growing a wide variety of plants.

Rockwool slabs are especially popular in marijuana cultivation, as they allow precise control of growing conditions, including humidity and plant nutrition. Their uniform structure and ability to retain moisture, while providing good aeration for the roots, promote rapid plant development.

How to use the rockwool slab:

The rockwool slab is a versatile and effective tool in hydroponic cultivation, and its proper use is essential to achieve optimal results. Here I present the recommended way to use rockwool slabs.

1. Do not remove the protective plastic from the slab: The plastic covering the rockwool slab should be kept in place. This plastic helps retain the shape of the slab and provides support for growing your plants.

2. Make a cross-shaped cut: On the top of the slab, make a cross-shaped cut in the plastic, which will create an opening for the plants. Make sure the cut is large enough to accommodate the roots of the plants.

3. Add a rockwool plug: On top of the cross-shaped cut, place a rockwool plug 7.5 or 10 cm in diameter, using adhesive tape to keep it in place. This plug will serve as the growing medium for your plants and provide additional support for their growth.

4. Make a cut on the bottom side of the slab: With a cutter or similar tool, make a cut along the bottom side of the slab. This cut will allow proper drainage of excess nutrient solution and water, preventing waterlogging and ensuring that the roots have access to oxygen.

5. Plant cultivation: The size of the slab (100 x 10 cm) allows the cultivation of 4 to 5 plants on the same slab. Place your plants in the openings created in the plastic and make sure the roots enter the rockwool plug for healthy growth.

By following these steps, you can effectively use rockwool slabs in your hydroponic cultivation. The combination of rockwool and protective plastic offers a clean and efficient growing environment for your plants.

Maintenance of the rockwool slab:

Given the continuous absorption of nutrients, it is very convenient to clean the slabs with an enzyme solution to help reduce the electrical conductivity (EC) of the growing medium.
