New Grow Started: Tray Prep\ Heating Mat Question


🌱2 Blueberry Fem (Seedsman)
🌱1 Gorilla Glue (California Family Share)
💧soaked seeds in PH water 5.6 24- 48 hours

🔒Blueberry seeds not cracked yet
🔓Gorilla Glue seed cracked showing small tap root

ℹ️Trying rapid rooter plug this time. Soaking that in PH balanced water

❓How do I prep my dome? I saw two videos with conflicting info. Should I pour water in the bottom of the tray?
❓Or let them sit after soaking in the tray base?
💀My last two grows ended with the seeds dying thr in rock-wool cube. Trying something different.
