First thing to do is buy a temp gauge (and i mean a reliable one.) My house is usually set on about 78 degrees F and i turn the vent off in the room with the shrooms so the temp is about at 80 all day. But if your house is colder just buy one of those work bench lamps with a steel cone over the bulb and experiment with mounting it different distances from your terranium. Keep the terranium covered most of the time so no light goes through but the light will produce heat that can be transfered into your terranium. BTW the lamps i'm talkin about are also great for drying shrooms. just wrap up the shrooms in a blak T-shirt and put them under the light (about 2ft away) overnite and they will be crispy dry in about 20 hours no noticable loss of potency. hope that helps------------------
