15kg Buffered Coco Peat Brick (Pack of 3 x 5kg) • Compressed • 3 Bricks Expands to up to 225L

Maximum value for serious growers — three of our professional-grade 5 kg buffered coco peat bricks in a single order. Together they expand to up to 225L of premium, peat-free growing medium: enough for a full greenhouse run, multiple large raised beds, or an entire season of propagation.

Every brick in this bundle carries the same tight quality tolerances as our single-brick offering. Pre-buffered to Ca:K ≥2:1. EC ≤0.50 mS/cm. pH 5.5–6.5. Batch-tested for consistent expansion and ion-exchange performance — no variation between bricks, no surprises mid-season.

• up to 225L total from three 5 kg bricks
• Calcium-buffered — every brick pre-treated, ready to use
• Consistent batch performance — uniform expansion across all three
• Best-value format for allotment holders, greenhouse growers, and commercial operators scaling up

Please note: Deliveries to remote postcodes (Scottish Highlands, islands, and some areas of Northern Ireland) may take longer than standard estimated times.

How to use:

1. Hydrate each brick: Place one or more bricks in a large tub, raised bed, or wheelbarrow. Pour 10–15 litres of water per brick evenly over each one.
2. Allow to expand: Leave for 15–20 minutes, turning occasionally. Each brick expands to approximately 75L — all three together give up to 225L of growing medium.
3. Break up and mix: Use a trowel or hands to break up any lumps until you have an even, crumbly texture throughout.
4. Use straight for hydroponic drain-to-waste runs, propagation trays, or any inert substrate system — no pre-flushing needed.
5. Blend for containers, raised beds, and greenhouse runs: Mix 50/50 with compost, or use 40% coco / 40% compost / 20% perlite for heavier-feeding crops and mixed systems.

Tip: All three bricks are batch-tested to the same spec — Ca:K ≥ 2:1, EC ≤ 0.50 mS/cm, pH 5.5–6.5. Consistent performance across every brick, every time.
