  • 💧moisture: does the soil feel very moist to the touch?
  • 🌡️temperature: is the setup away from direct sun, open windows, or heat vents? make sure it stays consistently between 70F-90F (use a heat mat if the temperature falls under 70F)
  • ☁️humidity: do you see condensation on the humidity dome? if not, make sure the dome is fully sealed, the setup is warm enough, and there's enough moisture in the soil.
  • 💚care: leave the dome on and only open it once a week to add water.
