Aquarium Tissue-Cultured Plants: A Comprehensive Guide

Tissue-Cultured Aquarium Plants: A Comprehensive Guide

Within the aquarium hobby, there are many options for buying aquatic plants. The most common method is buying emersed plants, usually in pots and bunches. These will usually come from a local nursery (domestic) or from a different country (international). Another common method is buying submerged plants. These plants have the highest success of growth, especially for beginners, but come with caveats. Both emersed and submerged plants have the possibility of having algae and pests, such as aquatic plants. 

For emersed plants, snails are much less common, but not impossible. The reality is that these snails, such as Lymnaeidae, can actually live outside water, and breathe air. They are able to thrive in high-humidity environments - the same environment where emersed plants are kept. They also are likely to have algae, especially in pots, where the root wall/substrate is kept submerged. 

Thus, for people who want to avoid all pests and algae, the best method to do this is buying plants from tissue culture. 

 Tissue Cultured Plants, What are they?

Tissue culture, also known as in-vitro propagation or micropropagation, is a huge method of propagation, not only with aquatic plants, but many different living things. There are may different things to culture, from mammalian cell culture and bacteria culture, to carnivores and house plant culture. Furthermore, there are many different methods to culture them, such as meristem culture, callus culture, seed culture, etc. However, in the aquarium hobby, we often refer to specifically aquatic plant tissue culture, with most using meristem culture. 

Are tissue culture plants artificial plants?

Tissue culture plants are not artificial plants. However, they are grown in artificial environments. These plants are grown in labs, where the plant is sterilized and grown in perfect conditions for the plant to thrive. They will be grown in media that contains a lot of natural chemicals and hormones that allows the plants to reproduce quickly. This is a difficult process, but with a lot of practice, these labs create the amazing plants that we now have in large quantities. 

From here, these plants are usually grown out and are how nurseries will have a large quantity of plants very quickly. As talked about, these plants are sterile. Hobbyists love this method of growing plants for many reasons: 

• Pest-Free: No chance of hitchhiking snails or algae in your aquarium 
• Healthier Plants: Grown in optimal lab conditions, tissue-cultured plants already are better adapted due to high humidity in their vessel
• Compact, Large Portions: Although the tissue culture cups seem small, these cups tend to have a lot of plants in their cups and come compact. For example, the Sreepadma GroWoW! Cryptocoryne spiralis 'Jwala' come with on average 15+ plants, and the Eriocaulon quinquangulare come with at least 3 adult plants, most of the time being able to become split into multiple young Eriocaulon.  

Preparing and Care for Tissue Culture 

Tissue culture plants are very easy to prepare and use, but there are a few important steps and tips to ensure success in your aquarium. 

Storing Tissue Culture Plants 
When you first receive your tissue culture cups, you have two main options, either planting immediately or storing the cup for later use.
One of the biggest advantages of tissue culture plants is that they can be stored for extended periods before planting. To ensure success in storing plants for later use, ensure these requirements are met:

• Keep the culture sealed: This prevents the sterile environment inside the cup from getting contaminated from air outside the cup. 
• Place the culture under moderate light: This allows plants to grow well and prevents stunting (inhibits growth) or stretching (commonly referred to "leggy plants"; longer internodes reaching for more light)
• Store at room temperature: Ideal conditions is between 60-70 degrees Fahrenheit, as slightly cooler temperature slows growth and prevents possible issues with gel melting or growth of bacteria / mold

In these conditions, tissue culture plants can last weeks or up to a few months. In fact, many hobbyists intentionally grow out cups to increase plant mass. This also mimics what is seen in pet stores, where tissue cultures are seen in well lit refrigerators. 

If the cup becomes cloudy, begins to dry out, or shows signs of contamination, it is best to quickly remove the plants within the culture and plant immediately. 

Preparation for Planting Tissue-Cultured Plants: From the Cup to Planted 

Before adding tissue culture plants into your aquarium, you must remove the nutrient gel they are grown in. This step is very important. Here is a quick guide to preparing the plants: 

• Break the seal from the cup and carefully pull out the plants - if you can pull out the entire mass of plants at once, this is better
• Gently rinse off all gel using clean water (tap water is fine)
• Carefully separate the plants into smaller portions 

Although getting the gel off the plants is important, it is not dangerous if not all the gel is removed. As long as most gel is removed (>95%), the remaining gel should not cause an issue. 

When dividing these plants, they should be divided into smaller clumps. Too large of clumps and there is the risk of the clump floating up after being planted, too small the clump and there may be the risk of some bigger fish eating the plants. Nonetheless, a clump of plants should be equal to about 10% (1/10) of the total area of the cup. Thus, at the end, one should achieve at least 10 total clumps for most tissue cultures (some cultures, such as rare plants, only come with a few plants in the cups - this rule does not apply to them). This allows plants to spread faster and establish more efficiently. 

To plant, use of thin tweezers allows for best precision and allows for the plant's fragile roots to not be damaged. Plant these plants until their roots are under the water, but make sure the crown is not submerged (if it applies to that genus). For Micranthemum 'Monte Carlo', it can be deeply planted. Even with a little sticking out, this allows success and helps prevent floating. 

Finally, for best success, make sure to follow these tips for the first 1-3 weeks of planting tissue cultures: 

• Maintain stable water parameters
• Provide consistent lighting 
• Use nutrients (such as liquid fertilizers) 
• Provide consistent and a proper level of CO₂ through injection (not necessary, but greatly increases success - especially with more difficult species)
