Mineral A+B by Maria Green is the definitive solution for growers who refuse to settle for mediocre harvests. This 2-part mineral fertilizer system is engineered to cover every nutritional need of your cannabis plants, from the first days of vegetation to the final week of fattening, ensuring maximum yield and rock-hard buds without the headache of mixing a dozen different bottles.
Let’s be real: trying to balance pH, EC, and ten different additives can turn your grow room into a chemistry lab nightmare. You worry about nutrient lockout, yellowing leaves, or worse—burning your precious plants just when they start to bloom. That uncertainty creates anxiety, and frankly, it takes the fun out of growing.
If you don't fix your nutrient regimen, you risk weak stems that can't support heavy flowers, or airy, flavorless buds that are embarrassing to show your friends. Why risk months of work and electricity bills on a diet that doesn't perform? Your plants are starving for stability, and improvising with generic fertilizers is a one-way ticket to disappointment.
The solution is simpler than you think. Mineral A+B simplifies the equation by splitting the essential nutrients into two concentrated formulas that, when combined in the water, provide the perfect synergy. It eliminates the guesswork, preventing precipitation and ensuring your plants absorb 100% of the food they need to explode with growth.
When you are alone in your grow tent, just you and your plants, you want a workflow that is smooth and stress-free. Using Mineral A+B gives you that feeling of professional control. You don't need to be a master grower to see master results; the formula does the heavy lifting for you.
It’s incredibly satisfying to mix your reservoir and know exactly what your girls are getting. The 2-part system allows you to adjust the intensity based on the plant's stage, giving you the precision of a pro without the complexity. It’s about enjoying the process of cultivation, knowing that every milliliter you pour is translating into vigor and health.
Growing is often a solitary hobby, but smoking is a social ritual. There is no better feeling than pulling out a jar of your own harvest, rolling one up for your crew, and watching their eyebrows raise after the first hit. Mineral A+B isn't just about green leaves; it's about maximizing terpene production and bud density.
When you use high-quality cannabis fertilizers like this, the difference in the final product is obvious. The ash burns white, the flavor is clean, and the potency is there. This product ensures that when you finally share your hard work, you’re passing around top-shelf quality, not something that scratches the throat.
To get the beast mode out of your plants, follow these simple tips. Remember, never mix pure A and pure B together directly; always add them to water one by one!
Yes, absolutely. While it is a staple for hydroponics, it works wonders in soil. Just make sure to alternate with plain water occasionally to prevent salt buildup, or use a soil improver like Maria Green Vegetable Humus for better buffering.
Some elements, like Calcium and Sulfur, can react and precipitate (turn into solids) if mixed in high concentrations. Keeping them separate until they are diluted in water ensures your plants can actually drink them.
Mineral A+B is a complete base nutrient. However, for that extra "pop" during the fattening stage, adding a PK booster is recommended, but this base alone will still yield excellent results.
It features a balanced profile with Total Nitrogen at 3.4% and Water-Soluble Potassium at 7.0%, along with Phosphorus and Magnesium.
I've tested dozens of nutrient lines over the years, from the organic vegan stuff to the heavy salts. What I love about Maria Green's Mineral A+B is the reliability. When I'm running a hydro setup or even just a quick indoor soil run and I don't want to complicate my life with charts, this is my go-to.
I've noticed that the plants stay greener for longer, and the transition to flower is super smooth. There's no "shock." Plus, the density of the nugs is legit. If you are looking for that dense, commercial-quality finish without needing a degree in botany, give this a shot. It just works.
