Bioavailable CalMag Fertilizer from Terra Aquatica
High availability of calcium and magnesium is crucial for the optimal nutrition of rapidly growing plants. It prevents secondary nutrient deficiencies, supports growth and fruit formation, and prevents blossom end rot and tip burn in high-yielding crops such as tomatoes and lettuce.
The highly concentrated Terra Aquatica Calcium-Magnesium Supplement provides both elements in a bioavailable, pure, and soluble form, ensuring no risk of clogging drippers. It can be combined with almost all plant nutrients.
When growing in coconut fiber substrate or hydrating coconut blocks, the Terra Aquatica Calcium Magnesium Supplement also prevents calcium from being "sequestered" by the coconut fiber.
Application of Calcium-Magnesium
Caution: Do not use together with Terra Aquatica formulations for soft water, DualPart Coco, or NovaMax – they already contain sufficient calcium, even when water is filtered by reverse osmosis.
Terra Aquatica coconut fiber products are systematically pre-rinsed and stabilized, allowing them to be planted right after unpacking.
In all other cases:
- For most applications, including organic cultivation and demanding species, use 1.5 ml per liter.
- For reverse osmosis filtration before adding nutrient solution, add 2 ml per liter to the water.
- When growing in coconut fiber, soil-free or soil-containing substrate mixes, or hydrating coconut blocks, use 1.5 ml per liter to moisten the medium (until saturation) and then add the same amount to the nutrient solution over the next two weeks. For fast-growing annual species, continuous application can be helpful.
Calcium-Magnesium is suitable for
Fertilizers from other manufacturers, hydroponics, and outdoor gardens.
Pro Organic in the required amounts when growing in coconut fiber, especially when using fertilizers from other manufacturers.
