Eco-Saturday: Grow your own sprouts

I love sprouts. They’re higher in protein and nutrients than lettuce and taste good in salads and sandwiches.

What I don’t love are the plastic containers in which they’re packed. Those clamshell boxes are usually recyclable, but the little humidifier pads at the bottom aren’t, and avoiding plastic altogether is generally better for the environment than using it once and then recycling it.

That brings me to one of my favorite winter projects: growing my own sprouts.

In this planting zone, December gardening is a no-go unless you have a heated greenhouse or a hydroponic operation. Sprouts, however, grow just fine on a shelf in the dining room, where I keep a sprouter going most of the winter.

Theoretically, you can grow sprouts in a canning jar with a piece of cheesecloth stretched across the top, but I’ve never had good luck with this approach. Small sprouters are available for about $20 apiece (I use this one, but any similar model will do), and they tend to work much better than the canning-jar approach.

Alfalfa seeds, left, and lentils, right, are good for sprouting. You'll probably have to hit the health-food store for alfalfa seeds.

Sprouting is easy, but like any other kind of gardening, it requires a little time and attention. Here’s the general upshot:

1. Change the water frequently. My sprouter is designed with stackable trays that have small drainage holes in the bottom. You run water in the top tray, and it percolates down, watering the sprouts at each level before collecting in a solid tray at the bottom. At least twice a day, I dump out the water, rotate the trays, and water the top one. (Don’t reuse the old water.)

2. Keep an eye on the drainage holes. As the roots grow, some may extend down into the holes and clog them up. If you notice water doesn’t seem to be draining right, sterilize a needle and use it to unclog the holes.

3. Don’t let your sprouts dry out. If your indoor air is really dry, you may need to cover the top to help keep moisture in for the first day or two. When the sprouts are about a quarter-inch long, remove the cover and start rotating the trays each time you water so the same tray isn’t constantly on top, where it’s more likely to dry out.

4. Stagger your plantings. Most varieties will go from seed to salad in three or four days. If you start new seeds every couple of days, you’ll have a constant supply of fresh greens. (Be sure to wash the trays in between harvests.)

You should be able to find sprouting seeds at any health-food store. You can also sprout brown lentils, which are available by the pound at pretty much any grocery store.
