Vital Organics by Grotek is the calcium boost your plants are screaming for, designed to strengthen cell structure and prevent deficiencies without the risk of toxic salt buildup. If you want robust stems capable of supporting heavy buds and a root system that functions at 100%, this chloride-free supplement is your best ally.
Have you noticed rust-colored spots on the leaves, weak stems that bend easily, or growth that just seems stuck? You are likely facing a calcium deficiency, one of the most common and frustrating problems for growers, especially when using soft water or inert substrates.
If you ignore these signs, the consequences are disastrous. Calcium is the "cement" that holds plant cell walls together. Without it, new growth deforms, roots become susceptible to rot, and the plant simply cannot support the weight of the flowers. Worse yet, many cheap calcium supplements on the market are loaded with chlorides, which accumulate in the soil as toxic salts, burning your roots and blocking nutrient absorption. You try to fix a problem and end up creating a worse one.
The solution is Vital Organics by Grotek. Unlike generic correctors, this formula uses calcium acetate derived from natural sources. It provides the exact dose of calcium your plants need to build an indestructible structure, but without the chlorides that poison your soil. It is the clean, safe, and effective way to ensure your plants reach the finish line healthy and productive.
Most calcium supplements are based on calcium nitrate or calcium chloride. While effective, they have "side effects." Chlorides increase the EC (electro-conductivity) with elements the plant doesn't really want in excess. Vital Organics focuses on quality over quantity.
By using calcium acetate, this product not only feeds the plant but also helps displace sodium particles that may be choking your roots. It improves the flocculation of the soil, allowing more oxygen to reach the root zone. It is the perfect choice if you are looking for high-performance cannabis fertilizers that respect the biology of your crop.
Using this supplement is simple, but because it is concentrated, you must follow the instructions to avoid overdoing it. It is designed to be used throughout the entire life cycle, from vegetative growth to flowering.
Yes, Vital Organics is compatible with most nutrient ranges. However, always add it to the water first, mix well, and then add the rest of your fertilizers to avoid precipitation.
Absolutely. Being chloride-free and derived from acetate, it is much friendlier to soil micro-life than synthetic mineral options, making it ideal for bio-growers.
You can use it until the final root flush. Calcium is immobile in the plant, so a constant supply is needed right up until the end to keep the buds healthy.
I've tested countless calcium supplements over the years, especially when growing in coco coir where calcium issues are a nightmare. What I love about Vital Organics is the peace of mind it gives me regarding salt buildup. I used to see burnt tips with other brands when pushing the EC high, but with this Grotek formula, the plants stay green and turgid.
I specifically use it at 2 ml/L once a week on my mother plants. Since I started, the cuttings I take root faster and have much thicker stems from day one. It's one of those bottles that doesn't look fancy but is absolutely mandatory on my shelf.
