things to know

  • Silver foliage: soft, lacy, almost white leaves that make other plants pop.
  • Cool-tolerant: sprouts well without extra heat.
  • Pick a planter that holds moisture: plastic, rice hull or ceramic, with a dome. Skip terra cotta, peat pots, coco coir pots and egg cartons. They wick water away from the seed.

plant care tips

  • Light: full sun or a grow light keeps the silver color strong.
  • Water: let the top dry between waterings; it dislikes wet feet.
  • Pinch flower buds to keep the foliage looking its best.
  • Feeding: light feeding monthly.

these are key aspects of your setup

check your setup!

  • 💡light: is your setup away from direct sun? these seeds should stay in indirect or filtered light, or better yet, under grow lights.
  • 💧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.
