Yes, there is bottom heat supplied by a heat mat that came with the enclosure. I also purchased a $12 Taylor digital temperature probe w/ alarm from Target (in the cooking section). The probe is inserted 2 inches into the soil of a peat pot. The heat mat is plugged into a timer. In this particular room, having the heat mat alternate on and off for 70 minute periods keeps the temperature in the 75 to 85 F range. The only light they receive is ambient -- the window they are near is partially shuttered and faces north.

Today's inspection revealed another tiny outbreak of white hairy fungus on the top of a different cutting which I cleaned and then treated with Physan 20 (an 0.2% solution). The growth buds on nearly all the cuttings are swelling. On a few of the ficus and lotus cuttings, some of the buds have started to sprout.
