Wood is by far the best material for seed trays. It provides seeds with the best possible start in life. I'm not sure whether it is because wood provides more insulation than plastic or whether slugs like it less, but my seedlings always do better in wooden seed trays.
These are a traditional design, with a slatted base and narrow gaps to allow drainage.
Made from waste pine collected from local builders. Comes in two classic seed tray designs, each 5cm deep and each compatible with the seed tray dribber:
- Small, 29cm x 17cm, £7
- Large, 38cm x 25cm, £8
