Abstract: A device holder is provided, which may receive and securely hold multiple devices, for example, ballasts or power boxes, of any make, model, or size. The device holder may minimize property damage and mitigate fire and safety risks. The device holder may be modular, allowing a user to arrange any number of devices onto a surface.

Abstract: A cloner may include a reservoir to hold a liquid, a lid with apertures to hold plant cuttings, stems, or roots, and a manifold mountable at or near a water line of the reservoir. One end of the lid may include a fan housing, and an opposite end may include ventilation holes. The reservoir may have a pump housing to hold a pump so that the pump does not become submerged in water, mitigating or preventing excess heat inside the cloner.
