DIY Indoor Grow Box

In February, Sarah pulled out our grow box–I had made it last year–and got our seeds started. I should have written this post then, so that others could have made their own this year, but unfortunately I didn’t. A friend asked how I made it, so I figured I’d post about it now so that you can build yours for next year. It’s quick and easy.

What you need:

  • plastic Rubbermaid-type bin with lid (the under-the-bed size works well)
  • 4 – 2 x 1/4 inch bolts, with 4 nuts, and 4 – 1 1/2 inch washers
  • 4 – 18 x 1/4 inch pieces of all thread rod, with 8 nuts, and 8 large washers
  • board (plywood or shelving) approximately 24 x 12 inches (dependent on your lid size)
  • 2 aquarium light fixtures with full spectrum fluorescent bulbs


1) On the inside of the lid, attach the board with the bolts and nuts, put the washers on the outside of the lid so the bolts won’t pull through the plastic. Line the board up in the inside center of the lid and drill a 1/4 inch hole through each corner of the board, with a matching hole through the lid. This board provides the stable surface to mount the light fixtures.

2) In each corner of the lid drill a 1/4 inch hole and put through the all thread with a nut and washer on each side of the plastic lid. The all thread will be the adjustable “legs”.


3) Mount the light fixtures, per the directions, to the board on the inside of the lid.



Once Completed

Plant your seeds – the container you choose doesn’t really matter, but make sure there are holes in the bottom for drainage. Place the containers in bin, adjusting the all thread so the light is close to the plants. As the plants grow larger the light can be lifted higher by adjusting the nuts on the all thread.

(I used 10 inch all thread, it was high enough when I first started but not enough when the plants grew bigger, so I cut blocks to put under each all thread leg to make them higher.)

After you’ve transplanted all of your sprouted plants, disassemble the legs and slide the entire box under the bed to neatly store until next year.

Simple and it works.
