Looking for some .02 on this idea. This spring there was a site from Woods Hole Ag Expermintal Station in MA. They made a greenhouse and heated with manure. They found that they could grow leafy veggies. But they had problems with fruiting veggies One of their conclusions was there was a lower quantity of Infared Radiation. in northern area's in the winter months. Yesterday I was in my local feed store and remembered from ?? years ago they used and infrared heat lamp to warm up chicken coops. I think that this IR should be close enough for plants. Any .02 Please mail your thoughts direct as it will be 3 or 4 days before this goes out. TIA Byron
