Phat Sacks are taking the grow world by storm, offering a tremendous and innovative improvement over traditional grow bags or plastic pots. Phat Sack brand grow containers have been designed with a breathable fabric material that allows much better oxygen and air flow at the root level, stimulating root growth which results in a much more robust plant. Additionally, the roots' exposure to this material creates what is referred to as an "air-pruning" effect, resulting in more branching and finer roots. At these prices (under $5 for our 5 Gallon Phat Sack Grow Pots), you owe it to yourself to give Phat Sacks a try. We're confident that once you've seen the difference firsthand, you'll never even think about going back to a conventional grow container ever again.
