Tissue culture aquarium plants,also known as 'in-vitro' plants - are manufactured in a laboratory using the latest tissue culture technologies to produce unique & high-quality plants in plastic polypropylene pots. They are grown in sterile conditions using a fertile gel/liquid. Guaranteed to be free from snails, pests, algae, and pesticides, making them perfect for shrimp keepers and any planted tank enthusiast. This technology also allows us to stock a range of smaller delicate plants that can be tricky to keep otherwise. We think aquarists are going to be buying tissue culture plants more and more in the future as there are many benefits.
