So right now I have about 300 Dubai Roaches in a 22gal tub. I have a 10inx10in screened hole cut in top with a 75w blue night bulb type guy on top. I also have a Zilla undertank heating pad underneath the one side. I have egg flats cut in half stacked together with a whole eggflat over top to "trap" in heat and also make sure it's super dark in there on one side. the other side being completely open with food/water. When I check the temp tho it's only saying about 82F and I know I need it higher in there for faster breeding. My house sits at about 74F throughout winter.... Any suggestions to help with the heating? Also What else can I throw in the tub other than the water crystals and roach chow to feed? I've been throwing in baby carrots which are gone instantly but was looking to change it up a little... Thanks so much
