Calmag - Biobizz: For Healthier Cells, Bigger Blooms, and Better Yields
Do your plants need extra support? Give it to them organically with Biobizz Calmag. Ideal for growers using soft tap water or RO setups (where calcium or magnesium deficiencies are common), Calmag is here to give your plants that little extra nudge whenever they need it.
Calcium and magnesium might not appear on NPK formulas, but they’re vital for healthy plant development. Both play central roles in cell structure, photosynthesis, and flowering. Unfortunately, regular water sources often lack these minerals, making deficiencies a common problem for growers in all setups and of all skill levels.
Luckily, Calmag provides your plants with all the calcium and magnesium they need in a 100% organic formula. Whether you’re supporting your plants or correcting a deficiency, Calmag is the perfect companion to your grow.
How to Use Biobizz Calmag
Calmag can be used throughout your entire grow alongside Biobizz Grow and Bloom nutrients. Adjust your dose based on your medium and whether you’re correcting or preventing a deficiency:
For prevention: In that pairing, Bio Grow is the bottle carrying plants through the vegetative phase. Nutrients and the wider run of grow supplies and gear are one section away.
