Window Shelves for Microgreens

A Micro-Farm for Microgreens

After a whole summer of planning, testing, number-crunching, and preparing, I’m finally ready to begin offering my first farm crop for sale. It’s November now, our growing season is almost over, and I have no greenhouse. But that’s just fine, because I’m going to be growing this farm crop right inside my kitchen!

Microgreens are one of my all time favorite crops, and I’ve been growing them for years. They take up very little space, require a low-tech setup, and they are ready to harvest within weeks. They’re also very delicious, exceptionally nutritious, and I have never seen them for sale at the grocery store. I usually grow a few trays on my window sills, but I need much more growing space if I want to grow enough to sell. So today I built these shelves to increase my window growing area. This new system will hold 30 trays of microgreens (a tray, for me, is a loaf pan).

How To:

To build these shelves, I used two 1x8x10 boards, and fourteen 15/8 length screws.

I measured the inner width of my windows (16.25″) and cut ten pieces of that length. Your cut length and number of pieces will vary based on the size of your window. These pieces will be the shelves.

I then cut fourteen 1.25″ pieces from the remnant board to serve as supports for the shelves. The number of support pieces you will need is equal to the number of shelves you intend to build that are positioned above the window sill.

The bottom shelf lies flat on the window sill, so it does not need any supports. I chose to do this instead of placing my trays directly on the window sill as protection from any water or stains that may dribble downward.

The higher shelves each rest on top of two support pieces. First, measure from the shelf below to reach a height above the tallest plants you want to grow. I give 13″ of vertical space to taller greens like peas and sunflowers, and 8″ of vertical space to shorter greens like broccoli and cabbage.

Once you find the height of your shelf, make a mark using a grease pencil or chalk. Use a box level or a ruler to make an identical mark on the other side at the same height. Secure one support piece to each side of the window frame along the mark you made with two screws each. Place your board to rest on top, then check to make sure that the shelf is level enough for your purposes.

I chose not to attach my shelf boards to the support pieces. They feel pretty sturdy resting on top, and I think the whole system will be easier to clean and maintain if the shelves are removable. However, if I find that they need to be more securely attached, I can always use an extra screw or two to attach them to the support pieces, or attach extra support pieces above the shelf boards.

Repeat adding additional shelves in this manner until your window is full or you have as much shelf space as your growing needs require.

Growing The Microgreens

I may write my own tutorial on growing microgreens someday, since I’ve been growing them for years now and I have developed my own style over time. But meanwhile, if you’re interested in learning how to grow your own, check your library for Peter Burke’s book “Year-Round Indoor Salad Gardening”. That’s the book I used to get started.

And here are photos of some of the delicious microgreens I’ve already grown in my kitchen!
