Much like certified organic farmers, veganic farmers use no synthetic chemical fertilizers, pesticides, herbicides or genetically modified ingredients.
Veganic farmers then take it to another level by not using any manure or slaughterhouse byproducts.
Stephane Groleau is co-founder of the Veganic Agriculture Network. He says he's aware of only a dozen veganic farms or gardeners in the U.S.
Bustos says he has a strong customer base that seeks out his produce because of the vegan growing philosophy as well as a growing awareness about food production.
He says it's the customers who are encouraging growers to find ways to become more environmentally conscious and efficient.
