So, I recently got an unbelievable number of root cuttings from my D. binata and capensis strains. (The edge of my D. binata dichotma's pot was a continuous coil of roots going down about two inches.) These are vigorous plants so I just gave them a SuperThrive bath and stuck them in pots without giving it much thought. Now I'm reading guides that all say to cover the containers until buds emerge. Do I really need to cover them for humidity? I would certainly make that provision for leaf cuttings but it seems like overkill for roots. Thoughts?
