Bootstrap Farmer started from a a small family farm in Eastern NC where we grew our own produce for a farm-to-food truck concept. Our focus has been growing vegetables and herbs in our high and low tunnel greenhouses. While growing our farm we noticed many things that could be done more efficiently and cost effective. Many greenhouse materials were of very low quality and poor construction. After hopelessly searching the market for better materials we started manufacturing our own. We have a passion for supporting our local farmers and providing our local community with healthy and sustainably grown food.

If that is not practical follow these guidelines.
