There are various types of heaters you may use, but be advised using ceramic heaters may be harmful to your plants. The hot ventilated air they blow dries up the atmosphere resulting in a low humidity level, which can be unadapted during vegetative period especially for clones and seedlings. Moreover, they can cause damages and even burn whatever is placed directly next to the heating unit itself, or too close to it.
