The number of plants you can grow in a given space is a highly disputed amongst growers, but here are some general guidelines will give you a broad idea of the number of plants you can maintain in popular tent sizes available:2.5' x 2.5' – 1 mature or 2 small plants3 ft. x 3 ft. – 2 mature or 4 small plants4 ft. x 2 ft. – 2 mature or 4 small plants4 ft. x 4 ft. – 4 mature or 8 small plants5 ft. x 5 ft. – 4 mature or 12 small plantsKeep in mind that the more space your plant has to grow, the better yields you will get from it. That is to say that two mature plants in a 4'x4' tent could yield as much bud as four mature plants. When in doubt, contact the manufacturer and ask if a specific tent will work for what you have in mind. JUMP TO GROW TENTSJUMP TO STARTUP KITS
