The bottle
Live on the shop as Growth Formula. Shake before use. One bottle comes in every Three by Four and Four by Four; this page is the refill. The quantity ladder is this page's: £7.99, £13.99, £19.99, then £5 a further bottle, up to six an order. That is not the Seed Pack ladder and not the One by One curve.
Why a mineral feed on coco
Coco coir holds water and air. It does not come loaded like a peat compost. The Coco Soil bag is pre-buffered with calcium and magnesium and charged; Growth Formula is the ongoing mineral feed once the plant is drinking. NPK 4-2-6 is the ratio on this bottle. THH has not published a house trial of this feed against another brand. The claim is the live bottle, the dose, and that it is sold for coco.
How to use
- Shake the bottle.
- Two pumps per litre of water.
- Use with every watering.
Coco wants a regular weak feed more than a rare strong one. Do not invent a third dose on this page.
