Called both a “mad scientist” and “plant geek," LLoyd's passion is matched by his commitment to using advanced technology. Lloyd worked in market research and special projects at Ball Seed Company prior to purchasing the Peace Tree Farm property in 1983, which he and his wife, Candy, have grown from “the little greenhouses up on the hill” to an established and internationally respected operation. Lloyd is a technology guru and advocate for small growers. He has contributed to GMPro, OFA, GPN, Greenhouse Grower, and GrowerTalks, and can be seen, from time to time, palling around in front of the camera with Martha Stewart.
