🌿 THE COCO GROWER’S GUIDE
Run-to-Waste Feeding Made Simple
Consistent. Controlled. High Performance.
Coco coir is one of the most powerful growing mediums available — when used correctly.
This guide explains the fundamentals so you can grow faster, healthier, and with fewer problems.
🧠 WHY COCO IS DIFFERENT
Coco is:
✔ Soilless
✔ Highly oxygenated
✔ Excellent at holding water
✔ Excellent at holding nutrients
Unlike soil, coco contains no nutrition of its own.
That means:
Every irrigation is a feed.
You are not watering in coco — you are feeding.
💧 THE GOLDEN RULE
Always feed nutrients.
Always water to runoff.
Each irrigation should produce 10–20% runoff from the bottom of the pot.
Why?
• Prevents salt buildup
• Keeps root zone EC stable
• Refreshes nutrients
• Maintains oxygen in the media
Never give plain water (unless correcting a problem).
⏱ HOW OFTEN SHOULD YOU FEED?
As plants grow, feed frequency increases.
🌱 Seedlings
• 1 feed per day
• EC 0.8–1.2
• Light runoff
🌿 Vegetative Growth
• 2–4 feeds per day
• EC 1.4–1.8
• 10–20% runoff
🌸 Early Flower
• 3–5 feeds per day
• EC 1.8–2.0
🌺 Mid–Late Flower
• 4–6 feeds per day
• EC 1.8–2.2
Small, frequent feeds are better than large, infrequent feeds.
📊 UNDERSTANDING EC
EC measures nutrient strength.
You should monitor:
• Input EC (what you feed)
• Runoff EC (what drains out)
If runoff EC is:
✔ Slightly higher than input → Normal
⚠ Much higher than input → Salt buildup
⚠ Lower than input → Overwatering
Monitoring runoff prevents problems before they start.
🌡 IDEAL pH RANGE
Target pH: 5.8 – 6.2
Why this matters:
• Too high → Nutrient lockout
• Too low → Toxicity
Consistency is more important than perfection.
💦 HOW WET SHOULD COCO BE?
Coco should feel like a wrung-out sponge.
Never:
✘ Let it dry completely
✘ Allow it to stay waterlogged
Healthy coco is always moist and oxygenated.
🧪 WHY CALCIUM & MAGNESIUM MATTER
Coco naturally binds calcium and magnesium.
Always use:
✔ A quality coco nutrient
✔ Or supplement with CalMag
This prevents:
• Yellowing
• Weak stems
• Slow growth
❌ COMMON COCO MISTAKES
• Feeding plain water
• Feeding once per day in heavy flower
• Letting coco dry out
• Ignoring runoff EC
• Running EC too high
Coco rewards consistency.
🏆 THE COCO SUCCESS FORMULA
✔ Feed every irrigation
✔ Always achieve runoff
✔ Increase frequency as plants grow
✔ Maintain pH 5.8–6.2
✔ Monitor runoff EC
✔ Keep coco consistently moist
When managed correctly, coco delivers:
• Fast growth
• Strong root systems
• Heavy yields
• High-quality flowers
