Since their launch, CANNA Substra Vega and CANNA Substra Flores are used worldwide by satisfied growers throughout. The composition of the products in the CANNA SUBSTRA product range is adapted to the needs of fast growing plants. CANNA Substra Vega and CANNA Substra Flores contain all the elements a plant requires in a form that can be absorbed directly, guaranteeing an optimal uptake as soon as the plant begins to grow. This results in maximum yield and full flavor. When growing in hydro culture the plant is 100% dependent on the nutrients provided in the irrigation water. And because this irrigation water is usually based on tap water CANNA has optimized its products for different types of tap water. The products are designed to prevent salts accumulating which will be damaging to the environment and your plants.
CANNA products basically distinguish between two key phases in the development of the plant. Initially the plant will gain height and grow many leaves in its growth or vegetative phase. CANNA has developed the plant nutrient CANNA Substra Vega especially for this phase. The plant then moves into the flowering or generative phase. As the plant’s requirements change it requires different nutrients: CANNA Substra Flores.
CANNA Substra Vega is a complete nutrient for the growth phase, specially developed for cultivation on inert media. Fast and healthy growth is characterized by vigorous shoots and good development of the root system and this forms the basis for achieving top results. CANNA Substra Vega contains all the nutrients a plant needs in this phase. You will need to apply the nutrient solution 1 to 3 times a day.
You must also make sure that 10 to 20 percent of the irrigation water with nutrients leaves the slab again! Under normal circumstances you will need 0.8 to 1.32 gallons of nutrient solution per square meter per day.
CANNA Substra Flores is specially developed for use during the flowering phase. During the plant’s flowering phase all nutrients must be available quickly and in the right quantities and ratio for the plant to absorb directly.
When using CANNA Substra Flores, ensure that the drainage is such that about 10 to 20 percent leaves the slab. This usually means applying 1.05 to 1.6 gallons per square meter per day.
This will ensure that all elements are directly available to the plant when the plant actually needs them.
How do you know when to switch nutrients? Well, during their first two weeks the plants will grow vigorously and then they will need considerably more water. When the first flowers begin to form is the right time to switch from CANNA Substra Vega to CANNA Substra Flores, this is usually 1 to 3 weeks after starting the photoperiod required for flower response. To prevent fertilizers from accumulating, and therefore any excess or shortage of specific elements occurring in the plants, the slabs could be flushed periodically. If it has not been necessary to flush the rock wool slabs prior to this change, then it is advisable to do so in the third week.
