Hi Heather,

Well, I don't know how large you want to grow your plants inside. In any case, the domes should have been removed after seed germination; or in the case of cuttings, after the cuttings have rooted.

The plants need good air circulation (a small fan on a timer is often used). Failure to remove the domes usually results in the soil (and plants) staying too wet. That often leads to damp-off, root rot, or other fungus problems. Domes and soil heaters are just for germination or rooting; they are not meant to be used for growing on.
