Key ideas in Growing Culinary Herbs Under Lights

  • Pressing basil seeds firmly onto the moist media surface prevents burying them away from light.
  • Light-sensitive seeds need direct photon exposure to convert phytochrome to active Pfr form.
  • Even a quarter-inch layer of seed-starting mix blocks light wavelengths needed to trigger growth.
  • Cilantro and parsley undergo enzymatic germination inhibition if exposed to direct light.
  • A dark vermiculite cap provides complete darkness while keeping the radicle humid.
  • Basil and oregano seeds abort germination if covered by dark planting media.
  • Condensation on domes scatters up to 30% of incoming light, causing seedlings to stretch.
  • Stagnant, high-humidity air under a dome allows damping-off fungi to girdle fragile stems.
  • Domes must be removed the instant sprouts break ground to introduce airflow and clear photons.
  • Overhead watering dislodges tiny surface seeds and washes them into dark crevices.
  • Bottom-watering draws water upward via capillary action to evenly hydrate the surface.
  • Consistent surface moisture prevents delicate seeds from drying out under intense grow lights.
  • One-sided light causes the plant growth hormone auxin to pool on the shaded side of the stem.
  • Auxin accumulation accelerates cell elongation on the dark side, bending the stem toward the window.
  • Diffused, directional windowsill light fails to provide the overhead intensity needed for tight internodal spacing.
  • Light intensity follows the inverse-square law, dropping geometrically as distance increases.
