Knowing how important the smart spacing is, we are pleased to provide you with a two-tier aluminum shelving kit, available in both 12 and 14 foot options. Remember that greenhouse is a high-humidity environment, so choosing shelves made of rust resistant materials is extremely important. Don’t forget to take into consideration is the ability to carry the weight of dozens of pots filled with moist soil and the plant itself. Made from durable aluminum, our shelving kit is designed to secure the comfortable and safe environment for growing your organic produce.
