Growing in Coco with Cropsalt Nutrients

A simple guide to feeding, watering, and getting the most out of your coco grow.


Why Coco Coir Rocks
Coco coir — made from the husks of coconuts — gives the best of both worlds: water retention like soil and oxygen flow like hydroponics. It’s clean, sustainable, and easy to control. Using a complete line like Cropsalt Nutrients makes this simple and consistent.


Understanding Coco’s “CEC” — The Nutrient Magnet
CEC stands for Cation Exchange Capacity — basically, how coco “grabs onto” nutrients. Fresh coco naturally holds potassium (K) and sodium (Na), which can block calcium (Ca) and magnesium (Mg). That’s why quality coco should always be pre-buffered or treated before use. Cropsalt Base nutrients ensure calcium and magnesium are available in your feed water, keeping coco stable and ready for root uptake.


Feeding in Coco — Consistency is Everything
Coco doesn’t store a reserve of nutrients like soil. Feed with every watering — no plain water days unless flushing to reduce buildup and increase ph. Every drop your plants drink should contain Cropsalt nutrients. Feed until you get runoff (20–30%) each time to flush salts and keep roots fresh. Keep feedings steady and consistent — regular feeds always beat occasional ones.


Moisture Management — Keep Coco Happy
Coco likes to stay evenly moist — never dry, never waterlogged. Think of it like a breathable 
sponge: always damp but airy. Water often: once daily for young plants and up to 3 feedings for mature ones. Always feed Cropsalt nutrients, never plain water unless its for a specific purpose. Ensure pots drain freely and pot never dries completely.


Monitoring and Adjusting
Coco growing is about small adjustments. If runoff becomes too strong or salty, water more often with the same Cropsalt mix to flush naturally. If runoff is weaker than your input, your plants are feeding heavily — slightly increase nutrient strength. The goal is steady rhythm and happy roots.

Signs to Watch

• Yellowing between veins:
check your runoff ph.
• Leaf tip burn: too much buildup — check your runoff ph.
• Droopy leaves with soggy coco: too much water — improve drainage
and increase drybacks.
• Dry crust on top: not watering enough.

The Cropsalt Advantage
Cropsalt nutrients crush in coco and hydro systems. They deliver balanced calcium, magnesium, potassium, and micronutrients — no separate Cal/Mag needed. They mix clean, deliver evenly, and work perfectly with frequent coco watering. Whether hand-watered or automated, Cropsalt keeps feeding simple, stable, and consistent.


Quick Checklist
■Use pre-buffered coco or rinse before planting.
■Mix Cropsalt nutrients for every feeding — no plain water.
■Feed often and get runoff each time.
■Keep coco moist but not soggy.
■Monitor runoff and plant health.
■Adjust frequency before changing strength.

Follow these steps and your plants will thrive — fast growth, strong roots, and big, healthy blooms powered by Cropsalt.
