Steps

  1. 1Assemble the shelving unit in its final location.
  2. 2Hang one or two LED shop lights above each shelf using chains or S-hooks.
  3. 3Plug the lights into a programmable timer set to 14–16 hours on.
  4. 4Place seedling trays on the shelves and adjust lights to 2–3 inches above the tops of the plants.
  5. 5Raise the lights every few days as seedlings grow.
  6. 6Add a small fan on the lowest setting to strengthen stems and prevent fungus.

Tools needed

  • ·Cordless drill / driver (if installing hooks)
  • ·Pliers for chain links
  • ·Tape measure

Common mistakes to avoid

  • ·Lights too far from seedlings — they get leggy
  • ·No timer — young plants need 14–16 hours of light daily
  • ·Forgetting a fan — still air causes damping off
  • ·Overwatering trays with no drainage

Maintenance tips

Dust the LED tubes monthly. Check timers each season. Sterilize trays with a dilute bleach rinse before reuse.
