okay, the hydroponic balls I ordered from a gardening outlet arrived today. A 10 L bag cost me the same as one 2.5lb bag I got at the SLC reptile expo. I know that sounds severe but by the time I paid a low order fee and shipping, it comes out about the same. If I had known I would have picked it up last month at the show. I won't get around to rinsing the stuff till this weekend and probably not get the layered substrate in till at least next week, so things will be slow in the making here. Then there is of course the highly debated watering. I did try a filtered fountain with my red-eyes and found that it was difficult to keep clean and since there are no "secrets" to maintaining one, I will most likely go with some sort of drip system. Since I am still a newbie to the wonderful world of Chams I appreciate all input and I know there are some world class habitat designers and caretakers out there. I thank you all who have previously posted and also to those in advanve of posting. There is still the issue of plants, etc., etc...
