CANNA Substra Flores A (HARD WATER HW)

CANNA Substra Vega
The growing phase of the plant is most important. In this period the plant lays the basis for the flowering phase and a high yield. The nutrients in CANNA Substra Vega contain all the essential elements for optimal growing during this phase.
Advantages of CANNA Substra Vega
Directly absorbable nitrogen compounds and trace elements
Suitable for all inert substrates
Dissolves directly
Vital side shoots and luxuriant root development
Hard water or Soft water?
'Hard' and 'soft' are terms used to describe the quality of many water sources. Hard water has a high mineral content, usually originating from magnesium, calcium carbonate, bicarbonate or calcium sulphate, which can cause hard, white lime scale to form on surfaces and growing equipment. Hard water may also have a high alkalinity and a high pH, meaning that considerably more acid is required to lower the pH in the hydroponic system to ideal levels.
While hard water sources do contain useful minerals (Ca and Mg), these can upset the balance of the nutrient solution and make other ions less available for plant uptake. Smaller growers can counteract this by making use of one of the many 'hard water' nutrient products on the market. Soft water, by comparison, is a low mineral water source. Often rainwater is 'soft'. Also, soft water is typically sourced from surface water − rivers, streams, and lakes − and has not been exposed for long periods to mineral bearing rock formations. It can also come from treated water (Reverse Osmosis), where most ions have been removed or replaced with single valance atoms such as sodium by water softening equipment.
Substra Hard Water or Soft Water?
The fertilizers in the CANNA SUBSTRA range are available in two versions, for hard water and for soft water. If the hardness of your water is 60-80 mg/L available Calcium or more, use the hard water variant. If the hardness of your water is less than this, then the soft water variant is recommended.
