Thanks for info, well the lack of light is not the problem then. Mine get basically the same light levels. What is with the clear plastic barrier around the side of the cloner?
That's a barrier for the dry season. I sometimes have to cover the cloner with a piece of clear vapour barrier to keep humidity in. The barrier there ensures that the plastic doesn't touch the plants. I'm not using it right now though, but I do mist the plants once every couple of days with plain water. My basement is extremely humid, but my office where my cloner tent is, is quite dry.
