Plants with great success!

Tissue Cultures are very young plants cultivated and delivered directly from the laboratory. The plants are guaranteed to be free from snails, algae and pesticides and, therefore, are harmless for sensitive shrimp and fish.

Success with your aquarium depends largely on the proper plant choice. In a Tissue Culture cup, you are getting many plants that can be divided into small portions and cover a larger area. Plants are compact from the start, so you will experience dense and beautiful growth if you give them the right fertiliser and CO2!

• Carefully take the plant out of the cup and rinse off the growing media.
• To prevent mildew and algae, rinse with chlorine-free water.
  
• Split the plant into 6-8 portions using your fingers or scissors (for small foreground plants).
  
• Plant portions into the substrate using tweezers.
