AUTO NUTES COCO ABC
Coco-optimised dry nutrients for serious growers.
Coco has its own chemistry. Feed it accordingly.
Dry A/B/C nutrition for coco, coco/perlite, drip irrigation and run-to-waste systems.
Developed to work together
AUTO NUTES + AUTO SOIL
AUTO NUTES and the forthcoming AUTO SOIL substrate were developed to deliver their best results together.

Why coco is different
Coco coir is not an inert root zone like rockwool, and it does not behave like an NFT system. Its cation-exchange capacity affects calcium, magnesium and potassium, so it needs a coco-specific nutrient balance.
Standard NFT / Rockwool Feed
- Built for an inert root zone
- Ca / Mg / K balance may not suit coco
- More correction may be needed
- Greater risk of imbalance

Frequently asked questions
Why not use a standard NFT or rockwool nutrient in coco?
Those feeds are generally balanced for inert media or NFT. Coco exchanges calcium, magnesium and potassium in the root zone, so AUTO NUTES uses a coco-specific balance.
Can I mix all three parts together before adding to the tank?
No. Dissolve each part separately first, then add to your reservoir in the order A → B → C.
What EC and pH should I target?
Use the feed chart as a starting point. For coco, a typical pH target is 5.5–6.0.
Can I use AUTO NUTES in automated irrigation?
Yes. It is suitable for reservoirs, drip irrigation and run-to-waste systems when mixed correctly and monitored with EC and pH.
Ready to grow with AUTO NUTES?
Take control. Feed smart. Get consistent results.
