Yes I got the PM. Thank you! I was able to find an excellent source of supply for a "Jumbo Marimo Moss Ball' on Amazon from the seller "Substrate Source" located in California (phone # 1-818-921-6341). They shipped me a baseball sized (3+ inch diameter) moss ball for a total cost of just $15.15, which included shipping. For that same size moss ball, the Malaysian supplier wanted $250 USD + shipping charges!!! I couldn't be more satisfied. I am now growing it under an LED TaoTronics 24 watt plant grow light using distilled water, with a little club soda added and a couple drops of API CO2 Booster added each day.
I hope that this information may help others who are looking for the Jumbo sized moss balls.
