How to Use Air Prune Seed Starting Trays

Fill trays with well-draining soil, taking care to not overfill. Lightly compress soil until firm, but not compacted. Mist the soil lightly and plant into media. After planting, bottom-watering can commence using a 1020 deep tray. Using a heat mat and humidity dome during early germination is also recommended.
