The inner core pot is a heavy duty net pot which fits down into the outer pot which has a slightly raised center dome and an air gap to exist between the pots.
The result of all these features is to create a growing environment that enhances humidity in the space between the two pots on the sides and at the bottom. Air flow is significantly improved which reduces potential root rot while increasing humidity. A further advantage of this design is that it contains the roots inside the pot by encouraging root growth "around and down" rather than over the top of the rim. Oxygen is key to happy roots and the Oxygen Core Dual Pot from rePotme is one special pot for your prized plants to thrive in.
We recommend watching the roots so that they don't become tangled between the two pots. Once the roots become well established and protrude through the inner net pot, we like to then remove the plant from the inner pot and place it in the outer shell for longer term growth. We think of the inner pot as a kind of training wheels set-up for orchids that need the optimum development environment. We don't want to leave the "training wheels" in place too long once the desired development has taken place which could result in an unnecessary challenge to free the roots at repotting time. Freeing roots can be done by snipping the inner net pot (preferably not the roots!). Replacement inner net pots and outer shells are available in all sizes.
