What matters

A starter chargeSeeding mixes carry 1.0 kg/m3 of NPK 14:16:18 and a wetting agent, so the trays take water evenly.

Fine enough for plug traysFine fractions, 0-5 to 0-10 mm, fill a plug tray evenly.

Less peat if you want itThe same recipes are made with 15% wood fibre or 10% perlite replacing part of the peat.

Questions growers ask

Can we get a sample before ordering?

Yes. We send non-commercial samples by courier. The sample itself, the courier freight and the documentation are charged, so ask us for the current cost and we will confirm it with the specification you want to test.

Can you mix a substrate to our own recipe?

Yes, and a good share of what we ship is exactly that. Send a specification, or the datasheet of what you buy today, and we will match it. The lines blend peat categories with perlite, clay, wood fibre, limestone, wetting agent and NPK 14:16:18 fertiliser, and can add Radigen, a slow-release micronutrient fertiliser.
