White Grow Bag (Black Interior) White/Black Grow BagsThe white surface reflects light, helping keep plants' roots cooler. These bags are a great low-cost alternative to plastic pots used by greenhouse growers. The bags have pre-punched holes for easy draining and stand upright when filled with media. They are widely used in greenhouse drip irrigation applications, and they're ideal for residential growers too! Try them with bedding plants, tree seedlings, tomatoes, bell peppers, cucumbers, and more.
