General Hydroponics FloraNova Bloom

Flowering plants demand elevated phosphorus and potassium while requiring reduced nitrogen—ratios that traditionally force growers to juggle multiple bottles and complex mixing schedules. FloraNova Bloom eliminates this complexity with a patented one-part formula delivering 4-8-7 NPK plus complete micronutrients in a single bottle, providing everything your plants need from flower initiation through final harvest.

This isn't a simplified compromise on nutrition. FloraNova Bloom uses the same breakthrough suspension technology as FloraNova Grow, keeping reactive nutrients stable in high concentrations until application. The 8% phosphate drives flower development and essential oil production, while 7% potassium enhances density and terpene profiles. The complete chelated micronutrient package—including 4% calcium and 2% magnesium—ensures plants maintain metabolic function throughout heavy flowering without the deficiencies that plague single-bottle competitors. To further enhance metabolic activity, many growers incorporate General Hydroponics Floralicious Plus Nutrients into their schedule.

Commercial growers and hobbyists alike rely on FloraNova Bloom for its proven performance across hydroponics, coco, soil, and continuous feed programs. When plants transition from vegetative to reproductive growth, simply switch from FloraNova Grow to FloraNova Bloom. No ratio calculations, no compatibility concerns, no multiple bottles—just shake, measure, and feed the complete flowering nutrition your crops need to maximize yields and quality. If your reservoir requires adjustment, General Hydroponics Liquid pH Down Nutrients is recommended to maintain the optimal range.

FAQ

When should I switch from FloraNova Grow to FloraNova Bloom?+

Switch to FloraNova Bloom when your plants enter the flowering phase, typically triggered by changing photoperiods (12/12 light cycle) or natural seasonal transitions for outdoor grows. Make the switch as soon as you flip to flowering light or see the first signs of flower initiation. The reduced nitrogen and elevated phosphorus/potassium in FloraNova Bloom supports reproductive growth rather than vegetative expansion. If you are starting new clones or seedlings during this time, consider using General Hydroponics RapidStart Nutrients to promote vigorous root development.

Can I use FloraNova Bloom throughout the entire flowering phase?+

Yes, FloraNova Bloom is designed for use throughout the entire flowering phase from initiation to harvest. The 4-8-7 NPK ratio provides adequate nitrogen to prevent early senescence while delivering the phosphorus and potassium plants need for flower development. For enhanced finishing, you can supplement with products like Liquid KoolBloom during late flowering. Alternatively, General Hydroponics Dry KoolBloom Nutrients is an excellent choice for a potent final ripening boost.

Do I need additional Cal-Mag with FloraNova Bloom?+

FloraNova Bloom contains 4% calcium and 2% magnesium, which is sufficient for most growing situations. However, if you're growing in coco coir (which binds calcium), using RO or heavily filtered water with near-zero starting minerals, or running heavy-feeding strains, you may benefit from a supplement like General Hydroponics CALiMAGic Nutrients. Monitor your plants for signs of deficiency—tip burn, interveinal chlorosis, or brittle stems—before adding supplements.

Why is FloraNova Bloom thicker than other liquid bloom nutrients?+

The thick consistency is a result of FloraNova's patented high-density suspension technology. This allows higher concentrations of reactive minerals to remain stable in one bottle without precipitating or reacting prematurely. The thickness indicates quality and potency—you're getting more minerals per milliliter than watery competitors. Always shake vigorously before use to redistribute suspended nutrients.

How does FloraNova Bloom compare to two-part bloom formulas?+

FloraNova Bloom delivers comparable results to two-part systems but with significantly less complexity. Two-part formulas require separate bottles to prevent nutrient reactions, while FloraNova's suspension technology keeps everything stable in one container. You sacrifice some customization ability (fixed NPK ratio) but gain convenience and eliminate mixing errors. For most growers, the performance-to-convenience ratio makes FloraNova Bloom the better choice compared to multi-bottle systems like the FloraGro, FloraBloom, and FloraMicro series.

Can I blend FloraNova Bloom with FloraNova Grow during transition?+

Yes, you can blend the two formulas during the flowering transition if you want to gradually reduce nitrogen rather than making an abrupt switch. Start with a 75% Grow / 25% Bloom ratio in week 1 of flowering, move to 50/50 in week 2, then 25% Grow / 75% Bloom in week 3 before switching to 100% Bloom. This gradual transition can benefit heavy-feeding strains that need more nitrogen support during early flowering stretch by utilizing FloraNova Grow alongside the bloom formula.

What EC/PPM should I target with FloraNova Bloom?+

Target EC depends on your crop type and growth stage. For most flowering crops, aim for 1.2-1.8 EC (600-900 PPM on the 500 scale) during early flowering, increasing to 1.6-2.2 EC (800-1100 PPM) during peak flowering. The feed charts provide starting points, but always monitor plant response and adjust accordingly. Heavy feeders may tolerate higher EC, while sensitive strains need lower concentrations.

Should I flush before harvest when using FloraNova Bloom?+

Flushing practices vary by grower preference. Some growers flush with plain water for the final 1-2 weeks to reduce nutrient content in finished flowers, while others continue feeding at reduced strength until harvest. If you choose to flush, consider using FloraKleen to help mobilize accumulated salts. Monitor trichome development and plant fade rather than adhering to rigid flushing schedules—harvest timing based on maturity produces better results than calendar-based flushing.
