Microgreen "farm" is pleasing chefs, teasing palates

He grows shoots, he scores

Mark Haberer pinches a tuft of minia­ture greens growing in a tray.
"Try these," he says.
A few chews.
"Curry?"
"Cumin," he says. "Cumin greens."
Haberer is one of the engines behind Grow Anywhere, a Weld County farm that coaxes "microgreens" — tiny shoots of lettuce, carrot, arugula, on­ion, sorrel and more — out of air, using something called aeroponics. The farm is the only one of its kind in the world, says owner Larry Forrest. "It's beginning to become a farm," says Forrest, an optometrist. "I knew there would be problems going from a garage to a production unit. But I knew somebody had to do it if aeroponics was ever to take off."

It hasn't quite taken off yet. Forrest sells 4-ounce boxes of microgreens ex­clusively to restaurants. They're too ex­pensive for most home cooks. But For­rest thinks one day, those cumin greens will find their way to your kitch­en table.

"I'd love to sell this stuff to anybody, but it's a numbers game," he says. "You've got to make a living."

Forrest and others affiliated with Grow Anywhere call it a farm. This is accurate. They do grow food and sell it. But the farm contains not a speck of soil. A metal structure shields the farm from the sun. The farmers pay no atten­tion to the skies; rainfall is irrelevant.

Forrest buys rectangular, white grates, the kind that are used to cap flu­orescent lights — he gets them at hard­ware stores — and places a mesh over them. He or one of the employees sprinkles seeds over the mesh-skinned grates, which are then placed in a slot in a tall box outfitted with lots of little sprinkler heads.

Every 30 minutes or so, around the clock, the jets spray a mist of water over the seeds.

Once the seeds have sprouted roots, which poke through the mesh, they are taken into the operation's greenhouse, 1,600 square feet of long tables lined with those white trays, which stand on their edges. Each tray leans into anoth­er tray, forming something like a tent.

MICROGREENS: Angled carpets of sprouts never touch soil on road to restaurants

When the seeds are still awaken­ing, misters spray them twice an hour. When the racks get moved into their angled posi­tion, they're wa­tered at the roots. Among the microgreens: bean, corn, cumin and rad­ish plants.

Bright grow lights — the farm's "suns" — hang above each tray.

More sprinkler heads, about 400 of them, spray the trays, also about twice an hour. In less than a week or as long as a few weeks, depending upon the crop, employees pick up a tray, take it to a back room or outside, cut the greens with scissors and place them in 4-ounce plastic containers that are put in refrigerators until they get shipped.

"The radish sprout is hotter than the radish. Your bean sprout tastes more like a bean than a bean. Their sweet corn shoots, those are my favorite. They have a really sweet flavor that almost masks the corn flavor. It kind of explodes on your palate," says Eric Longhmi, a chef at the Boulder Country Club.

Longhini says there are plenty of microgreen suppliers, but only Grow Anywhere uses aeroponics, which of­fers big advantages.

"We've gotten other kinds of micro-greens where they are still attached to the root system and you have to remove them from the root system, then rinse them and dry them and remove the dirt that is left on them," he says. "And that's annoyance."

With Grow Anywhere microgreens, "You can just put it straight from the package to the plate," he says.

Forrest first got interested in aeropon­ics about 20 years ago through his friendship with Rick Stoner, who says he invented aeroponics and is a partner in Grow Anywhere.

Stoner's Berthoud company, Agrihouse, develops a variety of products as­sociated with aeroponics. He's working on establishing a much larger aeropon­ics farm near New York to service the large concentration of high-end restau­rants that buy microgreens.

"What we are doing here with Grow Anywhere is trying to establish a brand," Stoner says. "That's our func­tion. To put this up, develop a brand, and find acceptance for it and an eco­nomic model... We can grow plants nat­urally without pesticides in an en-closed-loop system where you don't need sunlight or dirt. We can grow any plant that is grown in the soil."

Plants clearly excite Stoner, but de­spite the last name, Forrest doesn't think much about them.

"I've never had a green plant in my house," he says. "I'm just beginning to understand what the plants are here.

"I'm not doing this because of a love of plants. I'm doing it to show that it can be done."
