GROW-WEB also known as row cover acts like a greenhouse producing a micro-climate which encourages plant growth and development and also provides protection from insects, birds, diseases and frosts. Grow-web is air and water permeable and allows for ventilation. Because of its exceptional air flow and light penetration , it can be left on a crop for the entire growing season with the exception of vine crops, which need pollination. These include squash, cucumbers and zucchini. Our packaged grow-web is 12’x16′.
