Note: When selecting 2 part nutrients that have a part A and a part B, they MUST be used together for proper performance. CANNA Substra is the nutrient for systems in which the drainage water is not returned to the nutrient tank but drains away (Run-to-Waste / Open hydroponic systems): the most popular cultivation method in the Netherlands and CANNA Substra is the nutrient that is most used for this system. In the beginning of the growth phase, the plant lays the foundation for its eventual yield. Characteristics of a healthy and powerful growth are vital side shoots and a luxuriant root development. SUBSTRA Vega is developed especially to fulfil the plant’s needs optimally during this phase. SUBSTRAVega is applied to all types of inert mediums. A complete absorption of nutrients and water is guaranteed from the beginning of the cultivation because SUBSTRA Vega is rich in directly absorbable nitrogen compounds and trace elements.
