FloraNova® Bloom Liquid Fertilizer 4-8-7

FloraNova® Bloom is formulated with an N-P-K analysis of 4-8-7. To support plants during their heavy-feeding reproductive phases, this super-concentrated base is fortified with essential secondary minerals, providing 4% Calcium, 2% Magnesium, and 2% Sulfur. It also includes a built-in micronutrient package containing Boron, Chlorine, Copper, Iron, Manganese, Molybdenum, and Zinc.

FloraNova® Bloom is engineered to shift the plant’s energy away from vegetative growth and focus it entirely on reproductive development. By delivering tailored ratios of Phosphorus, Potassium, Calcium, Magnesium, and Sulfur, it enhances flower and fruit development. Furthermore, it supplies the fundamental chemical building blocks needed to fuel the plant's essential-oil and fragrance production potential

Yes, FloraNova® Bloom is a one-part base nutrient that contains all 14 essential elements plants crave. Because it operates on a simple "one bottle per stage" system (using Grow for veg and Bloom for flower), it eliminates the operational complexity of multi-bottle systems. While many commercial growers run FloraNova® Bloom alone in flower to streamline their SOPs, it remains fully compatible with optional program additives if specific water qualities or crop goals demand them

Because the formula is patented and extremely concentrated, small doses go a long way. The safe, typical working range is ≈ 3–6 mL per gallon of water, depending on the feed program and growth stage:

• Light feeding: Approximately ~3.4–4.2 mL/gal across bloom stages.
• Medium feeding: Approximately ~3.8–4.8 mL/gal.
• Aggressive feeding: Approximately ~4.8–6.0 mL/gal

You should switch from the vegetative base to FloraNova® Bloom at the first sign of flowers or flower initiation. To prevent shocking sensitive cultivars during this transition, General Hydroponics guidelines note that you can run half-strength Grow and half-strength Bloom together to equal a single full-strength solution during the transition week.

FloraNova® Bloom is designed for commercial-scale controlled environment agriculture (CEA) and is highly compatible with hydroponics, coco, soilless mixes, potted plants, and soil. Because the mineral package is kept completely water-soluble, it is engineered for clean operation in continuous liquid-feed programs, day tanks, and fertilizer injector setups with zero clogs.

FloraNova® Bloom must be stored sealed, upright, and in a cool, dry place out of direct sunlight and extreme temperatures. Unopened bottles maintain full potency for approximately 2 years, and opened containers should be used within a single growing season. The product is warranted to conform to its label specifications at the time of purchase for 1 year.

The FloraNova series is formulated to be used one part at a time. However, during the transition week into flowering, General Hydroponics guidelines note that you can run half-strength Grow and half-strength Bloom together to equal a single full-strength solution to soften the nutritional shift for sensitive cultivars.
