Description
Future Harvest Calnesium is a liquid cal-mag nutrient supplement for preventing blossom end rot and supporting calcium, magnesium, and iron availability in plants. This cal-mag supplement is also a calcium and magnesium booster designed to strengthen plant structure and support healthier growth.
Calnesium 2-0-0 is positioned as a nutrient additive or supplement that improves calcium, magnesium, and iron availability, helping reduce common deficiency-driven problems. One of its most practical benefits is blossom end rot prevention in tomatoes and peppers, where consistent calcium availability is directly tied to fruit quality. By supporting nutrient availability, Calnesium helps plants build sturdier cell walls, which supports stronger, healthier plant growth and improved yield potential in fruiting gardens.
The compact facts layer is simple and shopper-friendly: Calnesium is 2-0-0. Beyond NPK, the product is formulated to support calcium, magnesium, and iron absorption, with micronutrient support included. Key inputs are mineral and chelated sources, including calcium nitrate and calcium chloride for calcium support, magnesium nitrate for magnesium support, and chelated iron and chelated zinc (EDTA forms), plus sodium molybdate as a micronutrient source. This combination keeps the product focused on essential element availability without turning it into a complicated multi-part solution.
Calnesium is also positioned around performance benefits that matter in real gardens: stronger plant cells and tissues for increased resistance to stress, support for cell division and plant tissue development, and improved water, nutrient, and carbon dioxide uptake. Those function-level benefits tie directly to what growers want from a cal-mag supplement—stronger structure, steadier growth, and fewer setback symptoms when plants are pushing hard through active development and fruit set.
For system fit, Calnesium is identified for hydroponics and is also described as suitable for foliar application, giving you flexibility in how it can be used within a broader nutrient program without changing its role. If you’re looking for a liquid nutrient additive that supports calcium and magnesium availability, helps prevent blossom end rot in tomatoes and peppers, and reinforces sturdy cell wall support for overall plant health, Future Harvest Calnesium is a clean, purpose-built choice for that job.
