FLEXIBLE PLASTIC - These net pots are made of flexible plastic that can be squeezed into various shapes and can be restored to its original shape, which is beneficial for the root growth of aquatic plants. They are super lightweight yet durable. USED IN TWO WAYS - The slotted mesh net cup can be filled with soil and put into the planter, which is convenient for transferring to larger pots later when the root system is large. It can also be used underwater for you to observe the root growth. USE FRIENDLY - The bottom of the plastic net cups are designed with many holes to allow the roots to grow out of the pots and form a large root system. The lip helps keep the pot rigid and allows a place for the stem to grow within. WIDE APPLICATION - These 5 inch net cups are perfect for hydroponics and aquaponics.
