When your plants enter the bloom phase, every nutrient decision matters. RX Green Solutions Bloom A Concentrate is engineered for professional growers who demand precision — delivering the exact phosphorus protection and reproductive support your crop needs to push yields further, every cycle.
Why RX Green Solutions Bloom A
Bloom A is not a generic bloom booster. It's one component of Rx Green Solutions' scientifically developed 4 Part Professional Nutrient Series — a system built around patented technologies that optimize how plants absorb and utilize phosphorus during the critical reproductive stage. Unlike single-part bloom formulas that leave growers guessing, Bloom A works in precise synergy with Grow A, Grow B, and Bloom B to deliver every essential micro- and macronutrient at optimal levels. No guesswork. No additional additives required.
Trusted by large-scale commercial operations across the country, Bloom A has been validated in multi-site trials showing measurable improvements in plant biomass, dry matter, fruit set, and overall yield. This is professional-grade nutrition built for results.

Frequently Asked Questions
What makes Bloom A different from other bloom nutrients?
Bloom A uses patented technology specifically designed to optimize phosphorus uptake and protection during the reproductive stage — something most generic bloom formulas don't address. It's also part of a complete 4-part system, so there's no need to stack additional additives.
Do I need to use Bloom A with Bloom B?
Yes. Bloom A and Bloom B are designed to work together. When combined with Grow A and Grow B, the full system delivers all essential micro- and macronutrients your plants need during bloom. Using Bloom A alone will not provide a complete nutrient profile.
Is Bloom A compatible with hydroponic, coco, and soil grows?
Bloom A is formulated for professional soilless and hydroponic applications. It performs best in hydroponic systems and coco coir media. Consult the Rx Green Solutions feed chart for specific application rates by medium.
How should I store Bloom A Concentrate?
Store in a cool, dry location away from direct sunlight and freezing temperatures. Keep the container tightly sealed when not in use. Shelf life is best maintained between 50°F–85°F.
How quickly can I expect to see results?
Most growers report visible improvements in plant vigor and flower development within the first 1–2 weeks of the bloom phase when following the full 4-part feed program. Yield improvements are typically measured at harvest.
Is this product available in other sizes?
Yes. Rx Green Solutions Bloom A is available in multiple sizes to suit operations of all scales. This listing is for the 1 Quart Concentrate — Case of 12. Contact us for bulk or larger format availability.
