Gerald Hubbell is doing something different on his farm in Mt. Pleasant. In a greenhouse only 18 by 48 feet he has managed to grow 250-275 green and red bell pepper plants, 75 (three different varieties) tomato plants, 75-80 cucumber plants, 10 zucchini plants, 60-65 bush beans, squash, carrots, radish and basil. Just outside the greenhouse he's growing West Indian hot peppers, Jamaican hot peppers, okra and corn. And all of it is thriving. In fact, there are some days when Hubbell is hard pressed to keep all of the vegetables picked.
