A grow tent is a portable, reusable grow room made of a sturdy canvas exterior and will usually have reflective interior material to increase the effectiveness of its built-in grow lights. It offers insulation to retain the heat that the grow lights produce while stimulating plant growth. A grow tent allows you to recreate nature under your very own conditions. Grow tents are available in different shapes and sizes to accommodate different needs. Smaller grow tents are available for horticulturists looking to grow just a few plants, while larger ones are for those growing a full garden throughout the year.
