Most everything on the property is grown in tunnels鈥攍ong rows with a half-moon structure over top covered in plastic鈥攗sing a no-till farming method because he has found that it leads to less weeds. And with their setup, they have to pick weeds by hand and paying staff only to weed, he says, wouldn鈥檛 be profitable for them.
The tunnels are covered, but not closed on the sides in the summer. They鈥檙e covered to keep water off the leaves of the plants and regulate exactly how much water they get using his irrigation system using groundwater. A particularly heavy thunderstorm, hail or wet summer can wreak havoc on their crops without the cover.
Salvaterra says they first started without tunnels, because the yield was too unpredictable and not up to the quality he prefers when selling.
In the first small tunnel, one 100 on the property, he had dill growing on May 1, with space for eggplant to be planted. He also had three medium-sized tunnels, and in the only heated tunnel on the property, just behind his house, Salvaterra had tomatoes growing; he expected them to be ready to be picked the second week of the month.
Despite having a heated tunnel, he says he鈥檚 still careful about what he grows in there. For instance, he doesn鈥檛 grow tomatoes year-round; he鈥檇 need supplemental lighting for that, which wouldn鈥檛 be cost-effective. Instead, he uses the heated tunnel to extend his growing season for tomatoes.
鈥淧eople generally are going to bring cherry tomatoes [to markets] in July,鈥 Salvaterra says. 鈥淵ou're going to get a lot of months where there's not a lot of them, so you're not competing with anyone, but you're not going to pay to do that in the winter.鈥
In the winter, he limits what he grows to produce that doesn鈥檛 need as much light and can freeze and thaw, such as kale, spinach and swiss chard.
鈥業 WOULDN鈥橳 CALL IT FARMING鈥
Salvaterra got the idea for his process from a book he read when he first started gardening about farms on the outskirts of Paris in the early 1900s. Those farmers used methods to grow crops effectively on small plots of land, much like what Salvaterra is doing, to provide those in the city with vegetables year-round. They used cloches鈥擲alvaterra describes them as glass carboys with the bottoms cut off鈥攖o protect the plants and extend the growing season. At night, the plants would be completely covered, and during the day, the cloches would get tipped up to let air underneath.
They also timed everything out so that while one type of produce was being harvested, others were already growing. Salvaterra noted how labor-intensive it was, which is why he made modifications for his own use.
鈥淓verything out here is more gardening, but it's like a standardized form of gardening,鈥 Salvaterra says. 鈥淚 wouldn't call it farming. It's farming, but it's not like a farm when you鈥檙e driving by cornfields. If you see romaine growing in California, it's not like that. It's more like a standardized form. And the beds are constantly rotating. They always have something growing in them. To make enough money, you have to have a plan that you鈥檝e worked on for years where the timing鈥檚 all right.鈥
