FloraMax Flowering Enhancer 1L & 5L


SKU: N/A Brand:

FloraMax Flowering Enhancer 1L & 5L contains a carefully balanced combination of potassium and phosphorus and is supplemented with calcium, magnesium, and iron chelate to combat harsh grow room conditions:

  • Promotes strong and healthy floral blooms.
  • Strengthens plant structure during heavy fruiting stages.
  • With most nutrient brands, ‘Flowering Enhancer’ avoids needing a ‘calmag’.
  • Unlike regular PK additives, Flowering Enhancer helps lock pH below 6.5 by improving the nutrient’s pH buffering by over 500%.  This prevents pH-related deficiency symptoms, even when hard water or alkaline additives are used.

3-in-1 additive: 

1. PK additive. 2. Cal-Mag-Iron additive. 3. pH stabilizer.

FloraMax Flowering Enhancer 1L & 5LFlowering Enhancer’s unique 3-in-1 action radically simplifies flowering and enhances final yield:

  • Promotes strong and healthy floral blooms:

Flowering Enhancer contains a carefully balanced combination of phosphorus (P) and potassium (K).  This provides the necessary base levels of “PK” for the flowering phase of plant growth.  PK is essential for promoting large and vigorous floral blooms.

  • Replaces Cal-Mag-Iron additives and prevents common growth deficiencies:

Flowering Enhancer contains high levels of calcium, magnesium (0.4%), and iron chelate (aka “cal-mag-iron”). This simplifies growing by preventing the need for a standalone “cal-mag” additive – EVEN when using RO, rainwater, or coco as a growing medium. Cal-Mag-Iron helps prevent common deficiency symptoms such as leaf yellowing/chlorosis, leaf curl, stunted growth, and withered fruit set.

  • Strengthening plant structure during heavy fruiting stages: 

The combination of calcium and magnesium will help strengthen the plant structure during late bloom when plants may have to bear the weight of heavy fruit and will assist plants in their capacity to utilize phosphorus.  Research indicates that Phosphorous can increase the dry weight at harvest.

  • Prevents the need for pH maintenance: 

Flowering Enhancer improves the working nutrient’s pH buffering capacity by over 500%. This helps lock pH below 6.5 and stabilizes the working nutrient solution to help prevent pH-related deficiency symptoms, even when hard water or alkaline additives are used. For soil and coco, pH adjustment is rarely needed. For recirculating systems, growers will require about FIVE times less’ pH Down than normal.

  • Available in larger pack sizes:

1L & 5L

  • Dosage:

2ml/L (7.5ml/Gal) throughout the flowering phase.



  • Should I be adding *extra* PK additives to the FloraMax feeding schedule during bloom?  

No, the PK levels (Phosphorous and Potassium) are optimized with Flowering Enhancer, Resin-XS, and the FloraMax base nutrient (VegaFlora AB or Veg-1).  Avoid using Resin-XS during early bloom as extra PK may negatively impact yields with certain strains.  During mid-to-late bloom, we generally recommend using Resin-XS at 3ml/L (11.5ml/Gal).  However, for heavy feeders, Resin-XS can be used at upwards of 4ml/L (15ml/Gal).

  • Can Flowering Enhancer be used in veg (or flower) with OTHER nutrient ranges?

Yes.  In veg, many growers now use Flowering Enhancer to prevent purple stems and petioles and to avoid calcium, magnesium, and iron deficiencies.   In bloom, Flowering Enhancer integrates very well into other ranges along with Resin-XS as the stand-alone PK additive.  This combination prevents the need for a cal-mag additive, provides pH stability, and prevents the need for messy resin enhancers, carbohydrates, and finishing agents.

  • When using FloraMax, do I need a “cal-mag”?

No, the FloraMax line is designed to eliminate the requirement for additional “cal-mag” additives as it is built into our base nutrients and Flowering Enhancer product.  Over hundreds of test grows during the development phase there was never any need for a dedicated cal-mag additive. Furthermore, the use of additional “cal-mag” may result in excessive calcium precipitate leading to clogged lines or build-up in the reservoir.

  • Why then does FloraMax manufacture a “cal-mag”?

To address the deficiencies found in competing brands.  We are committed to helping growers achieve their best results regardless of the nutrient regime they follow, our Ca-Mg-Fe product is ideal for use with other regimes.
