Product Description:

FlexiPot is an expandable and flexible gardening pot. This plant pot can be expanded (manually) when needed to accommodate plant growth and contracted when necessary to save storage space. Most pots come in a fixed form, which compels garderners to Re-pot their growing plant to another new pot. This process could be problematic for both the plant and its gardener. For the Plant, instances like tearing/snapping of roots, stem or leaf breakage, soil contamination, transplant shock (due to sudden change in soil type, moisture or pot size)- are some of the most common and lethal mishaps. As for the Gardener; it is inconvenient time consuming. ‘Flexipot’ aims to solve both of these (Plant and Gardener) aspects as it's an expandable plant pot that can eliminate the need for re-potting. It can be expanded as required and filled up with new soil, allowing the plant to grow without moving/repotting it. The selected material for this pot is Polypropylene Homopolymer (PPH) which is going to used for injection molding in order to make the pot.
