Hemianthus Callitrichoides, or HC for short, is probably the most popular foreground carpeting plant of the moment. It is actually one of the smallest aquatic plants in the world and only been around the hobby for 10 years or so. If cared for properly, HC will trail along your bottom of your tank to form a lush green carpet. It does best with co2 injection and good circulation. This is often overlooked but a very important factor in the success of growing HC. Ideally you need a flow rate of 10 x your size of the tank, and you literally need to see the co2 bubbles rolling over the plant at the bottom of you tank. If you are not injecting co2, liquid carbon offers a great alternative method.
How to prepare your HC pots:
Here’s how we prepare our HC for planting.
First of all, remove the whole plant including rock wool out of the pot. Then tear the plant in to two pieces.
Next, carefully cut away the bulk of the rock wool. You do not need the majority of the rockwool that comes with the plant.
Using scissors, cut the HC into smaller portions (about 1-2cm each). This allows you to cover more ground when planting.
After this you can start planting your HC. Using planting tweezers grab the roots of the plant and push into your substrate. Be careful not to bury too deep. Plant each bunch about 2cm apart and cover the desired area. It’s easiest to plant whilst you tank is yet to be filled with water. Every so often spray the plants to avoid them drying out.
