FAQs
What is BioBizz CalMag?
BioBizz CalMag is an organic calcium and magnesium supplement designed for plants. It's formulated to prevent and correct deficiencies of these essential nutrients. CalMag promotes strong cell walls, enhances photosynthesis, and supports overall plant health. This liquid fertilizer is suitable for all growing mediums, including soil, coco coir, and hydroponic systems. It's particularly beneficial for fast-growing plants and those prone to calcium or magnesium deficiencies.
How do you use BioBizz Cal-Mag?
To use BioBizz Cal-Mag, mix per liter of water as recommended. Apply this solution during regular watering or as a foliar spray. For best results, use Cal-Mag weekly throughout the growing cycle, especially during vegetative growth and early flowering. Adjust the dosage based on your plants' needs and signs of deficiency. Always shake the bottle well before use and ensure the pH of your nutrient solution is between 6.0-6.5 for optimal nutrient uptake.
Why should you choose BioBizz CalMag?
Choose BioBizz CalMag for its organic composition and effectiveness in preventing nutrient deficiencies. Benefits include: 100% organic ingredients Suitable for all growing mediums Enhances plant structure and growth Improves nutrient uptake Prevents blossom end rot in fruiting plants Boosts chlorophyll production Compatible with other BioBizz products Easy to use and mix Supports overall plant health Certified for organic cultivation
Can BioBizz CalMag be used as a foliar feed?
Yes, BioBizz CalMag can be used as a foliar feed. For foliar application, mix 1ml of CalMag per liter of water. Spray the solution evenly on both sides of the leaves, preferably in the early morning or late evening to avoid leaf burn. Foliar feeding with CalMag allows for quick nutrient absorption and is especially beneficial when plants show signs of calcium or magnesium deficiency. Always test on a small area first.
When should I start using CalMag?
Start using BioBizz CalMag from the early stages of plant growth, typically 2-3 weeks after germination or transplanting. Continue use throughout the vegetative stage and into early flowering. CalMag is particularly important during periods of rapid growth, in coco coir or hydroponic setups, and when using RO (reverse osmosis) water. Increase frequency if you notice signs of calcium or magnesium deficiency, such as yellowing leaves or stunted growth.
Is BioBizz CalMag organic?
Yes, BioBizz CalMag is 100% organic. It's made from natural sources of calcium and magnesium, including seaweed extracts and mineral deposits. This organic composition ensures it's safe for use in organic gardening and won't introduce harmful synthetic chemicals into your growing environment. BioBizz CalMag is certified for use in organic agriculture and complements other organic nutrients and growing methods.
Can I use CalMag in hydroponics?
Absolutely! BioBizz CalMag is highly effective in hydroponic systems. In fact, it's often essential in hydroponics, where calcium and magnesium can be quickly depleted. When using CalMag in hydroponics, start with a lower concentration (about 0.5-1ml per liter) and adjust based on plant response. Monitor your EC (electrical conductivity) levels closely when adding CalMag to your nutrient solution to maintain the proper balance.
How often should I apply CalMag?
Apply BioBizz CalMag once a week during regular feedings. However, the frequency can be adjusted based on your plants' specific needs and growing conditions. In coco coir or hydroponic systems, you may need to use it with every watering. Increase application to twice a week if you notice signs of calcium or magnesium deficiency. Always monitor your plants closely and adjust usage accordingly to avoid over-fertilization.
Can CalMag be mixed with other nutrients?
Yes, BioBizz CalMag can be mixed with other nutrients and supplements. It works well with the entire BioBizz product line and can be combined with most organic and synthetic nutrients. When mixing with other products, add CalMag to your water first, then add other nutrients. Always perform a small test when combining new products to ensure compatibility and avoid precipitation. Adjust your overall nutrient regimen as needed when incorporating CalMag.
Where can I buy BioBizz CalMag?
BioBizz CalMag is available from various gardening supply stores, hydroponic shops, and online retailers. You can find it on major e-commerce platforms or through BioBizz's official website. When purchasing, ensure you're buying from a reputable seller to guarantee product authenticity. CalMag typically comes in 250ml, 500ml, and 1L bottles. Choose the size that best fits your gardening needs and scale of operation.
