SCIENCE BEHIND THE FORMULA
Understanding why our 8-16-36 formula works so well for cucumbers and vine crops requires looking at the unique nutritional demands throughout their growth cycle.
The Role of Each Nutrient
Controlled Nitrogen (8%): Cucumbers need sufficient nitrogen for vine development, but too much creates problems. Excessive nitrogen leads to:
- Excessive vine growth at the expense of fruit production
- Delayed flowering and reduced fruit set
- Increased susceptibility to powdery mildew and bacterial wilt
- Poor fruit quality with bitter compounds
Our 8% nitrogen content provides optimal growth without these negative effects.
Enhanced Phosphorus (16%): Phosphorus is critical for cucumbers because it:
- Stimulates early root development for drought tolerance
- Promotes abundant flower production
- Improves fruit set percentage
- Enhances energy transfer during rapid fruit development
Very High Potassium (36%): Cucumbers are extremely heavy potassium feeders. This essential nutrient:
- Regulates water uptake and prevents bitter fruit
- Activates enzymes for sugar transport to developing fruits
- Strengthens cell walls for crisp texture
- Improves disease resistance, especially to fungal infections
- Extends post-harvest shelf life
- Reduces malformed and hollow fruits
Why Cucumbers Need High Potassium

FREQUENTLY ASKED QUESTIONS
Click on each question to see the answer.
Why is 8-16-36 the ideal ratio for cucumbers?
The 8-16-36 ratio is specifically formulated for the unique needs of cucurbit crops:
- 8% Nitrogen: Provides adequate vine growth without excess that delays fruiting
- 16% Phosphorus: Enhanced P promotes abundant flowering and fruit set
- 36% Potassium: Very high K is crucial for fruit quality, size, and storage life
This ratio produces maximum yields with superior fruit quality and extended harvest periods.
How does this prevent bitter cucumbers?
Bitter cucumbers are primarily caused by stress and improper nutrition. Our formula helps prevent bitterness by:
- High potassium regulates water balance in fruits
- Controlled nitrogen prevents excess vine growth that stresses plants
- Balanced nutrition reduces environmental stress response
- Micronutrients support proper enzyme function
For best results, maintain consistent watering and supplement with Cal-Mag Plus during fruit development.
Can I use this for greenhouse cucumber production?
Absolutely! Our formula is ideal for greenhouse cucumbers:
Greenhouse Application Rates:
- Seedlings: 0.25 lbs per 100 gallons
- Vegetative: 0.5 lbs per 100 gallons
- Fruiting: 0.75-1 lb per 100 gallons
Special considerations:
- Monitor EC closely - greenhouse plants are more sensitive
- Increase Cal-Mag during rapid growth periods
- Adjust based on variety (European types need higher EC)
- Perfect for drip irrigation systems
What's the best schedule for continuous harvest?
For maximum continuous production:
- At Planting: Apply starter dose (3g per plant)
- First Flowers: Increase to full rate (5g per plant)
- First Harvest: Begin weekly applications
- Peak Production: Apply 2x weekly or fertigate continuously
Pro tips for extended harvest:
- Foliar feed weekly during heavy fruiting
- Increase potassium (use extra 0-0-50) during peak production
- Never let plants dry out during fruiting
- Harvest frequently to encourage more fruit set
