What changes in coco
Coco holds very little nutrition of its own. The plant relies on what you deliver, so most growers feed at most irrigations rather than every few days. That changes the maths: lower strength, more often.
Coco also holds onto calcium and magnesium and can release potassium and sodium early in its life. Buffered coco and a reliable calcium and magnesium supply matter more here than in soil.
Starting the line in coco
- Use the chart as your rate reference and start at the low end. Start low. Read your plant. Then climb.
- Keep SPARK in from the first week: it covers the calcium and magnesium coco asks for.
- Run KICKOFF once a week. Coco has no native biology, so this is where it helps most.
- Aim for steady runoff and track runoff EC and pH so you see trends early.
Hydro and drip lines
Organic liquids carry organic matter. In recirculating hydro or fine drippers that matter can build up, so filter well, flush lines between runs and test a small section first. Hand-watered coco is the easy place to start.
Get a plan for your setup
Send us your medium, pot size, irrigation method and volumes, and we’ll build a coco schedule around your grow. We’d rather do that with you than publish one chart for every coco setup.
