Bio Calsimag Calmag Foliar Spray Foliar Feed
Calsimag is an organic foliar spray to supplement mineral deficiencies. Makes your plant less susceptible to pests, insects and other unwanted diseases. Cellmax Bio CalSiMag is a ready-to-use CalMag foliar spray containing calcium, magnesium and silicon. You apply the mineral feed directly to the top and underside of the leaf. The spray is intended as a targeted supplement when a plant does not receive sufficient availability of these elements via the roots. The minerals are derived from micronised rock. According to Cellmax, the particles have been reduced to approximately 7 microns so that they can be finely distributed over the leaf. In addition to calcium, magnesium and silicon, the formula contains humic and fulvic acids.

A strong soil life starts at the roots
In healthy soil, plant roots work together with beneficial fungi and bacteria. Cellmax Product X brings these micro-organisms directly to the root zone. The mycorrhizal fungi form a natural network around the roots there. In this way, they help your plant to utilise water and available minerals from a larger part of the soil. Free Shipping

100% vegetable
Did you know that almost all potting compost and fertilisers contain animal residues? We believe that animal residues do not belong in gardens or nurseries. Cellmax products are therefore made exclusively from vegetable ingredients.
The botanical ingredients we use at Cellmax come for example from potatoes, beets and sugar cane. Our bottles show exactly which ingredients are in them, so you know exactly what you are feeding your plants.
Pure organic
When we say organic, we really mean organic. All Cellmax BIO products are certified by Control Union and are therefore suitable for use in controlled organic agriculture and horticulture. With the BIO line, you have everything you need for growing your plants in a pot, greenhouse or vegetable garden.
Do what is right for your plants
Plants have different stages of development. From the seed, a seedling sprouts. From this the seedling develops, followed by the growth and fruiting phase. If you use the right nutrients during each phase, your plants will become stronger and greener. They will produce more fruit and taste better too.

All about fertilisers and additives
Organic fertilizers
Plants need nitrogen to grow. Traditional potting soil contains added nitrogen from animal waste and the chemical industry. Cellmax organic potting soil uses only plant materials that together provide the nitrogen in your soil. This process is slightly slower than with traditional fertiliser. It is therefore wise to use Cellmax organic plant food. There are different products, which have been specially developed for different purposes. These include a healthy soil life, a powerful root system and optimum support during the growth and flowering phases of your plants. All Cellmax nutrients contain an accurate NPK ratio and additional natural vitamins, proteins and acids. These ingredients combine to ensure optimum plant growth, more fruit and better taste.
Organic additives
Additives are additives you use alongside fertilisers to help plants grow and flourish optimally. Often, additives have a specific function, such as stimulating root growth or improving soil life. For this purpose, we have developed a number of organic products. Because when you grow organically, of course you also want to use organically certified additives.
