im planning on building an incubator out of a wine cooler, measures 31 high, 22 deep and 19 wide. the incukit heaters now come in 125 watts. would that be sufficient to heat that area does anyone know? i could use 2, but then thats just more expense (they arent that cheap!) if i dont have to. the wine cooler is very well insulated. any help would be appreciated! thanks!
