What the AI looks for in Plant Germination Trays
- Standard size
- Nominal 10 x 20 inch 1020 format That is the size cell inserts, humidity domes and seedling heat mats are designed around.
- Holes vs no holes
- No holes for an outer bottom-watering tray; holes for an inner tray or microgreens A tray with holes cannot hold water for bottom watering.
- Wall thickness
- Rigid trays that do not flex when full of wet soil Thin trays bend, crack and spill when lifted and rarely last a season.
- Insert fit
- Cell inserts labeled for 1020 trays (for example 72-cell or 50-cell) Mismatched brands can sit loose or fail to fit inside the tray.
Brands that matter
- Bootstrap Farmer: Heavy-duty 1020 trays and cell inserts.
- Epic Gardening: Durable reusable seed-starting trays and cells.
- Hydrofarm: Widely available standard trays and domes.
What to avoid
