Indoor growing trials

Microgreens, pea shoots, herbs and cuttings grown indoors under a grow light.

SetupWhat I was growing

The materials were simple; the variables weren’t. Light strength and distance, moisture, airflow, seed density, growing medium and timing all change the result.

A change today may only show after several days, and a small difference can compound across a whole tray, so I photographed each stage instead of relying on memory.

ExperimentsWhat I tried

The useful questions were practical: how densely should seeds be placed, when should the tray be uncovered, how does the light change the shape of new growth, and what happens when a cutting moves from water into a growing medium?

  • Changing one condition at a time made the results easier to compare.
  • Photographs were more useful than trying to remember earlier growth.
  • The setup needed to be easy to water and check every day.
