Pick of the Issue this week is Ian Frazier’s “High-Rise Greens,” an absorbing account of how a mini-farm installed in the corner of school
cafeteria led to the creation of a huge “vertical farm” inside a former
steel-supply warehouse in Newark, New Jersey. Frazier visits the vertical farm
and describes its technology:
Countless algorithm-driven computer commands combine to
induce the greens to grow, night and day, so that a crop can go from seed to
shoot to harvest in eighteen days. Every known influence on the plant’s
wellbeing is measured, adjusted, remeasured. Tens of thousands of sensing
devices monitor what’s going on. The ambient air is Newark’s, but filtered,
ventilated, heated, and cooled. Like all air today, it has an average CO2
content of about four hundred parts per million (we exceeded the
three-fifty-p.p.m. threshold a while ago), but an even higher content is better
for the plants, so tanks of CO2 enrich the concentration inside the
building to a thousand p.p.m.
He describes the lighting:
The L.E.D. grow lights are in plastic tubing above each
level of the grow tower. Their radiance has been stripped of the heat-producing
part of the spectrum, the most expensive part of it from an energy point of
view. The plants don’t need it, preferring cooler reds and blues. In row after
row, the L.E.D.s shining these colors call to mind strings of Christmas lights.
At different growth stages, the plants require light in different intensities,
and algorithms controlling the L.E.D. arrays adjust for that.
He also visits the mini-farm in the cafeteria at Newark’s Philip’s
Academy. He calls the mini-farm an objet d’art. I relished his description of
it, particularly this line: “The pumps hum, the water gurgles, and the whole
thing makes the sound of a courtyard fountain.”
Frazier is a great nose writer. Almost every one of his
pieces contains a description of some sort of smell. In “High-Rise Greens,” he
mentions a corner of the vertical farm, “where the fresh, florist-shop aroma of
chlorophyll is strong.”
Frazier takes time to note details that other writers
usually disregard. For example, in “High-Rise Greens,” he observes that
AeroFarms technicians “wear white sanitary mobcaps on their heads.” Then, in
the next line, he adds, “Some of these workers are young guys who also have
mobcaps on their beards.”
My favorite scene in
“High-Rise Greens” takes place at a grocery store. Frazier writes,
At the Bloomfield ShopRite, I watched a woman pick up a
clamshell of AeroFarms arugula, look at it, and put it back. Then she picked up
a clamshell of Fresh Attitude arugula and dropped it in her cart. I asked her
if she knew that AeroFarms was grown in Newark. She said, “I thought it was
only distributed from Newark.” I told her the arugula was indeed Newark-grown
and explained about the vertical farm. She put the out-of-state arugula back,
picked up the Newark arugula, and thanked me for telling her. I think AeroFarms
does not play up Newark enough on the packaging. They should call their product
Newark Greens.
That “At the Bloomfield ShopRite, I watched a woman pick up
a clamshell of AeroFarms arugula, look at it, and put it back” is delightful, like
a line from a James Schuyler poem, logging the slight but profound epiphanies
of everyday life.
“High-Rise Greens” brims with Frazier’s sharp-eyed observations.
I enjoyed it immensely.
