Yes, above clear line cover. I.e.. for many years my success was predicated on growing above 3500 feet elevation. In a tropical rain forest, the cloud cover was tremendous. The drawbacksd were the mold and loss of crop, but planting extra for that was no problem. Also, do not do patches, planting within the natural foliage where allowable, patches tick out, onzy twozy's do not. Happy Growing
