Starting your seedlings from seed can be frustrating.  Major complaints are that seedlings either do not sprout or they get very tall and spindly.  A light box can help with both problems.  

  • a wooden melon crate  or other box 22" x 13" x 13"
  • plywood 22" x 13" x 3/4"
  • a fluorescent ballast for two 15W tubes*
  • 4 bi-pin fluorescent lamp holders*
  • 2 15W fluorescent tubes
  • grounded extension cord
  • wire nuts
  • flathead screws 6 x 3/4"
  • white faced corrugated or white paper
  • 24 hour timer
  • Drill & bits
  • Screw driver
  • wire cutter
  • wire stripper
  • staple gun and staples

Step 1: The Box

My wooden melon box has slats and wide gaps along both sides and the bottom.  Lay the box on its side.  The open top is now the open front of the light box and the former side is now the top.  Cut the corrugated to fit the back and the two ends of the box and staple it in place.  This is to reflect the light and to keep it inside the box where it will help the seedlings. 
If you use one warm white and one cool white fluorescent bulb instead of two of the same type, you'll get something closer to full spectrum light for your plants.
