Ecothrive Feed Chart – Coco Doses for 15 Litre Pots
Ecothrive's own published coco coir schedule. Week by week, per litre of water, with Charge measured per 15-litre pot.

Ecothrive's coco chart sits on top of the base feed you already use. Dose that to its own maker's chart, then add the Ecothrive products in the weeks shown. Water and spray doses are per litre; Charge is grams per 15-litre pot.
Getting it right
- Keep your own base feed. The top row reads Label all the way across. That means feed your coco A&B at its own maker's rate every week. Ecothrive say any coco-specific liquid feed works with this chart.
- Neutralise first, and only on tap water. One drop per litre, or 1ml per 20 litres, in every watering. It strips chlorine and chloramine so the microbes in Biosys and the extract in Flourish survive. On RO water you can leave it out.
- Charge is a top-dress, three times. 3–6g per 15-litre pot, which is one to two teaspoons, scattered on the surface at Grow 3, Flower 2 and Flower 4. Nothing in the weeks between. Ecothrive's usage instructions give the rates for other pot sizes.
- Biosys starts strong, then settles. 1g per litre at Grow 1 and Grow 2, then 0.5g from Grow 3 to Flower 7. It stops for Flower 8 and Flower 9.
- Make Biosys up as a concentrate. For a big tank, dissolve the powder in a little tepid water first. Ecothrive's example is 10g in 250ml. Stir that into the tank and use the mix within 24 hours.
- Flourish: root feed or spray, never both. As a root feed it is 0.5ml per litre from Grow 1 to Flower 2, then 0.25ml from Flower 3 to Flower 8. As a spray it is 10ml per litre from Grow 1 to Flower 2 only. Pick one method, not both at once.
- Trace is the optional extra. It has no row on this chart. Ecothrive suggest it when your base feed runs weak, at EC 1.2 or below, at 0.25ml per litre.
- The last column is nearly empty. At Flower 9 Biosys and Flourish have both stopped. Only your base feed and, on tap water, Neutralise are left.

Common questions
Does Ecothrive make the base feed for this chart?
No. The chart is built to run alongside a coco base feed from another maker, and Ecothrive say any coco-specific liquid feed works. Dose it to its own chart.
My pots are not 15 litres. What changes?
Only Charge. The water and spray doses are per litre, so they hold for any pot. Charge is a top-dress, so its amount scales with the pot; Ecothrive's usage instructions give the rates for other sizes.
Can I use this chart in soil?
No, it is the coco chart. Ecothrive's living soil schedule is worked out for your own room by their online calculator, because it depends on pot size, soil volume and how long you run each stage.
How much is one drop of Neutralise?
Ecothrive give 1ml per 20 litres as the same rate, which is the easier way to dose a big tank.
Why does the chart restart at 1 for flowering?
Growers count flowering from the switch to 12 hours of light. Ecothrive's three growth weeks are Grow 1 to Grow 3, and their nine bloom weeks are Flower 1 to Flower 9.
