This price is for both Canna Substra Vega A & B - you get 2 bottles.
CANNA SUBSTRA 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 SUBSTRA is the nutrient that is most used for these systems.
CANNA Substra Vega is a complete professional nutrient for the growing phase of plants that are grown in inert (such as rock wool) run-to-waste systems.
