Make sure the rockwool slabs are horizontal. If they are not truly horizontal the moisture will run to one end of the slab. This could mean that some plants become too dry and others too wet.
CANNA HYDRO
CANNA HYDRO is the nutrient for cultivating plants in systems in which the drainage water is not returned to the nutrient tank but drains away. An advantage of these systems is that plants get fresh nutrients at each feed. This minimizes the risk of diseases. Also, the substrates used in these systems are mostly inert. This means they don't add or take nutrient elements from the nutrient solution, so you can grow with precision.
These systems are called run-to-waste or open hydroponic systems. CANNA HYDRO is the nutrient that is most used for these systems.
CANNA Hydro Vega is a complete professional nutrient for the growing phase of plants.
It is specially developed for growing in inert run-to-waste systems. In the beginning of the growing phase, the plant lays the foundation for its eventual yield.
CANNA Hydro Flores is a complete professional nutrient for the flowering phase of plants.
It is specially developed for growing in inert run-to-waste systems.
Tip Keep slabs horizontal
