Grain Filling — Weight and Eating Quality
Grain filling sets 1000-grain weight and eating quality, and depends on potassium to move assimilates into the grain. Insufficient potassium raises the share of empty husks.

What Hejia Hejia is for
A high-potassium fertilizer with calcium for fruiting, coloring and pre-harvest stages: better color, more sweetness and less cracking.

It helps with
- Slow coloring and low sweetness
- Fruit cracking, tomato blossom-end rot and hollow melons
- Weak rice stems that lodge late in the season
Highlights
- 25% potassium helps crops build sugars for better color, sweetness and fill.
- Calcium strengthens cell walls to reduce blossom-end rot, cracking and hollow fruit.
- Rice: stronger stems against lodging. Tomatoes and other nightshades: even coloring. Melons: larger fruit that is less likely to be hollow.

Why HERMEN — Your Benefits
- Supports sweetness, coloring and aroma for better marketable quality.
- Calcium strengthens cell walls to reduce blossom-end rot, cracking and hollow fruit.
- Pure and low in salt, less likely to scorch leaves even in hot weather.
Application Focus
From fruit sizing through color break, 25% potassium drives sugar accumulation and filling, while calcium supports cell walls, firmness and transport quality.
Suitable for tomato, pepper, melons, guava and aromatic rice quality stages. Calcium management should be paired with steady irrigation and avoidance of wet-dry swings.

Recommended Growth Stages
Hejia Hejia is recommended at the following growth stages. Open a stage for the full guidance.
Leafy Vegetables
Pre-Harvest — Shelf Life
Post-harvest softening traces back to insufficient tissue density and potassium. Potassium raises turgor and structural strength, directly affecting how produce survives transport and shelf time.

Color Break & Ripening — Sweetness and Firmness
Sweetness and color are governed by potassium, which moves sugars into the fruit, while calcium strengthens cell walls and skin — the key to reducing cracking and blossom-end rot. A high-potassium, calcium-containing formula with stable irrigation works best here.

FAQ
Sweetness and coloring are governed largely by potassium, which transports and accumulates sugars produced in the leaves into the fruit. HERMEN Hejia Hejia (NPK 15-6-25 + Ca) carries 25% highly water-soluble potassium for the color-break and sweetening window, lifting sugar, aroma and color. Its high-efficiency calcium supports fruit firmness and transport durability, in a clean formulation that will not scorch foliage.
Blossom-end rot is not a pathogen but a shortfall or transport failure of calcium during fruit development, aggravated when water supply swings. Hejia Hejia supplies high-efficiency calcium in water-soluble form for regular application through fruit development. Pairing it with steady irrigation, avoiding wet-dry extremes, makes the difference far more pronounced.
Cracking comes from insufficient skin strength combined with sharp changes in water status. Calcium strengthens cell walls and skin elasticity while potassium regulates fruit water balance; when both are adequate, cracking incidence generally falls. Apply Hejia Hejia continuously from fruit sizing onward alongside stable irrigation management.
Sugar content depends on potassium accumulated before maturity; continuing with nitrogen-led nutrition at this point grows the tree rather than the sugar. Switch to a high-potassium formula late in fruit sizing. The 25% water-soluble potassium in Hejia Hejia is taken up quickly, and its calcium adds flesh firmness, giving fruit both sweetness and texture with better storage life.
Aroma and eating quality in rice are closely tied to potassium supply during grain filling — with enough potassium, grains fill fully and eating quality improves. Hejia Hejia is imported ready-formulated with 25% water-soluble potassium and high-efficiency calcium; applied during grain filling it supports aroma, flesh density and storage durability together.
