• Rubber tree can survive well in low light space, and gets very tall
  • Succulent wall garden seems pretty doable. Needs bright light
    • Use moss not dirt, don’t overwater, you’ll need a lot of sucs
    • Get planted directly through a mesh wire
  • Either go with simple stack of boxes (light below each) or an array of circles to swap

Growing Lights

  • Bulbs are usually CFL or LED. CFL are cheaper to buy, cost more to operate, and last shorter. No impact on growth performance.
  • Light temperature (K) influences how plants grow. Generally cooler temperatures are going to be a safer bet, no less than 4000K. reference
  • Light intensity (lumens) determines how much stuff can grow. Because of the square law dimmer lights need to be closer, brighter can afford to be farther. have to figure out what you are growing before you bother
  • Wattage tends to correlate with light intensity, but not directly. Only matters for electricity bill
  • Color rendering index (CRI) is a metric that evaluates how close a light spectrum is to sunlight. It is fairly flawed because it only applies to human visible colors and it overrepresents pastels and warms. Higher CRI is likely better for growing, but it’s not at all the full picture.
