instructions

  1. Pick your spot. Greens and radishes fit a windowsill; tomatoes, peppers and cucumbers need big pots and strong light.
  2. Sow. ¼" deep for most seeds, ½" for peas and beans. Start fruiting crops in a 12-cavity mini greenhouse and transplant.
  3. Warmth. Greens sprout at 65–70°F; tomatoes, peppers and eggplant like 75–80°F on a seedling heat mat.
  4. Light. 14–16 hrs/day of strong light or a grow light.
  5. Thin and transplant. Thin greens, and move fruiting crops to 2–5 gallon pots once they have true leaves.

plant care tips

  • Light: the biggest factor. Fruiting crops need a strong grow light indoors.
  • Water: keep evenly moist; containers dry out fast.
  • Feeding: veggie fertilizer every 2–3 weeks once growing.
  • Pollination: shake tomato and pepper flowers gently, or use a small brush.

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.
