Thanks for understanding. https://www.grassrootsfabricpots.com/raised-bed-assembly/ MoistureLock™ is a strip of BPA-free waterproof fabric sewn to the inside of the container that provides many benefits. Directs water downward. This helps to avoid dry pockets in the soil. Promotes even moisture throughout the soil. Regular fabric pots dry from the sides. MoistureLock™ prevents that, simulating the way soil dries in nature. This helps the microbiology thrive. Less water usage! There is less surface area for water to escape the container, which means less water usage (lower labor) and lower humidity indoors. Aeration and air pruning comes from the 4” strip of breathable fabric towards the bottom of the container. 4 x 4 Bed fittings: Basic = All Fittings to Connect to your PVC.
