US (TX): Growing year-round lettuce in hot and humid Houston

“This entire greenhouse can be run with 7,000 heads of lettuce per week with just two people operating it.” At Sustainable Harvesters in Houston, Texas, Andrew Alvis & Matthew Braud grow a variety of lettuce using aquaponics.

In this video by LANDiO Matthew gives a tour of the 12,000 square feet greenhouse, which is soon to be expanded to 20,000 square feet. He tells about the cultivation process and explains how they control the climate within the greenhouse, to be able to grow produce year-round. “Here in Houston it gets up to the 105, 110 degrees with almost a 100 percent humidity. So growing these products outdoors is only limited to the springtime and the late winter. This greenhouse allows us to trap the heat in the winter and cool this place down in the summer utilizing a couple different components throughout the greenhouse.”

“In winter our only real concern is getting the water for the tilapia at the right temperature. In summer we control the airflow by creating a wind tunnel through the greenhouse that moves the humidity up and out of the greenhouse.”
