Additive feeding Calcium Green House Feeding

Mô tả chi tiết sản phẩm

Additive feeding Calcium is a bulk mineral fertilizer developed by Green House Seed co. This fertilizer is user-friendly and easy to use as it is highly concentrated and focuses on supplementing the nutrient solution with calcium. The raw materials used are of the highest quality produced in the EU. Power feeding is cost effective, easier to use, store and transport and has a longer shelf life than liquid fertilizers.

Additive feeding Calcium should be used in situations where the amount of calcium in the water is below recommended levels.
Our calcium is chelated with EDTA - this product is very stable and does not interact with other elements. Chelated calcium is a more accessible form to plants and prevents and corrects deficiencies that are caused by imbalances in calcium assimilation.
If you use reverse osmosis (R/O) water, calcium must be supplemented. Test the water with an EC meter.

Dosage:
R/O and very soft water - <70 ppm - 1-0.8 g/l
Soft water - 70-140 ppm - 0.5-0.8 g/l
Medium hard water - 140-220 ppm - 0.1-0.5 g/l
Hard water - >220 ppm - no need to add

Can be added to the top dressing or as a foliar spray (0.5 g/l).
