Thank you for the welcome! I initially used rock wool with a nutrient solution, but cut a slit in the top to the tray to accommodate a small powerhead to circulate the water. Unfortunately this compromised the total humidity and the plant leaves started to whither on some plants. Since the post, I decided to try a light aquatic substrate mixed with laterite and plant the Pusilla with the crowns and part of the plant submerged. I will insert an air hose from a pump and CO2 gas hose in the water column and then seal it with Saran wrap to prevent humidity loss. Then enough oxygen and CO2 will be present to facilitate growth. I also have a reptile heating mat sandwiched between glass under the tray to keep the water warm. Hopefully this will be successful. Don M. |
