Peat-Free Coco Coir Block 70L – Jiffy PRO7
⚪ Type: Unfertilised / Blank Canvas
No nutrients added at all. This gives you total control over feeding from day one, with zero risk of the substrate fighting your own nutrient plan. The trade-off: start feeding straight away, as there's no built-in safety net.
Jiffy PRO7 Coco Block – 70 Litres of Peat-Free Growing Media in a Box You Can Carry
A 70-litre bag of compost is mostly water you're paying to have driven to your house. The Jiffy PRO7 Coco Block takes the opposite approach: 5kg of compressed, professional-grade coco pith that expands to a full 70 litres once you add water at home. It's lighter to carry, easier to store flat in a shed or under the stairs, and far cheaper per litre than buying bagged peat-free compost or a stack of small coir bricks.
It's 100% buffered coco pith, ready to use, RHP certified for consistent quality and low salt, and wonderfully airy for fast, vigorous root development.
Perfect For
Peat-free potting for houseplants and aroids, raised beds and allotment plots, improving heavy clay soil, container veg like tomatoes, chillies and strawberries, seed and cutting mixes (blended with perlite), and hydroponic coco systems.
A Genuine Peat-Free Alternative
With peat extraction increasingly restricted and more gardeners choosing peat-free, a single coco block is one of the most cost-effective peat-free soil improvers available. Dig it into beds and borders to improve structure and water retention without a single scrap of peat.

How to Prepare
- Hydrate: place the block in a large container such as a wheelbarrow, trug or large tray.
- Add water: about 30 litres for a drier mix (if you'll water plants in after potting) or 35 litres for a wetter mix (for direct planting). Lukewarm water expands it faster.
- Fluff: leave for 15–20 minutes, then break it up with your hands or a fork for an even, airy texture.
- Mix: now's the time to blend in perlite or clay pebbles if you want extra drainage.
- Plant: pot up, or dig straight into a raised bed or allotment plot.
Feeding
Coco contains no nutrition of its own, so start feeding with a coco-specific nutrient from the first watering, beginning at a low dose for young plants and increasing as they establish. In very soft water areas, add a calcium-magnesium supplement during growth.
🌿 Rose's Pro-Tip: you don't have to expand the whole block at once. Saw or break off a chunk and hydrate just what you need; the rest keeps indefinitely while it's dry.
