Rockwool drains excess water quickly. Yet, it retains small amounts of water near the bottom of the cube. This unique property allows plants to attain adequate hydration while allowing more air to circulate and oxygenate the roots. This difference in moisture levels from the top to the bottom of the cube makes rockwool ideal for hydroponics.

* Agricultural Grade Rockwool
* Suitable for seeds germination
* Cube Size: 2.5cm x 2.5cm x 2.5cm
* 50 cubes per sheet
* 8 sheets 400 cubes

Preparation: Rockwool has a naturally high pH of 7 to 8. Prepare a solution of slightly acidic water (pH 5.5 to 6.5) by adding several drops of lemon juice. Soak the rockwool cubes in this solution for about 2 hours.

Sowing Seed: Place 1 or 2 seeds in the hole at the top of the rockwool growing medium. Water using a hydroponic nutrient solution. When the plants are 2 to 3 inches (5 to 7.6 cm.) tall, they can be transplanted into soil or placed in a hydroponic garden.

Due to its physical properties, rockwool growing medium can cause irritation to skin, eyes and lungs.
