Light is not needed unless leaves are present. Do keep a close eye out for new growth though, because when foliage emerges, it will need light! Many types of plants will produce foliage in a relatively short time once planted in warmer conditions, so your storage in the dark probably won't last long.

Many hardwood cuttings will root quickly submerged in damp compost kept about 80 degrees, no light needed. Al
