Seed Starting Trays

Start your seeds easy with seed starting trays

Purple seedlings growing in plug trays

Seed trays create a consistent workspace for germination, watering, bottom watering, and early seedling growth. This collection includes 1020 flats, cell trays, inserts, mesh trays, humidity domes, and specialty propagation formats.

Choosing seed-starting trays

  • Cell count: higher counts fit more seedlings; larger cells provide more root volume
  • Depth: match tray depth to the crop and time before transplanting
  • Drainage: confirm whether the tray has holes and whether a solid bottom tray is required
  • Compatibility: check exact dimensions before combining inserts, flats, domes, and watering trays
  • Durability: compare material thickness and intended reuse

Build a seed-starting setup

Pair trays with a suitable seed-starting mix, heat mat when the crop benefits from warmer media, grow lights, and plant labels. Monitor moisture at the media level and follow crop-specific temperature, light, sowing-depth, and transplant guidance.

Tray names are not a guarantee of interchangeability. Verify product dimensions and quantities before ordering components from different systems.
