Huperzia hamiltonii is best cultivated in a glasshouse or large terrarium. The plant you purchase from Araflora will be a young specimen, approximately 10 centimetres in length. When choosing a pot, remember that this type of plant can grow to be both large and heavy.

Huperzia hamiltonii does not require a great deal of attention. Only water it when the surface of the substrate has dried out. This will usually be at three-day intervals although watering can take place every day if the weather is especially warm. Huperzia hamiltonii needs plenty of light but should not be exposed to direct sunlight or intense light of any kind. It requires a high level of ambient humidity at temperatures between 15⁰ C and 30⁰ C. The best kind of substrate is a combination of bark chips and sphagnum moss. If the potting medium is too dense it will prevent roots from forming properly. Always make sure that water drains from the pot and do not prune the plant. Good air circulation around the plant is important as it helps to prevent infection.
