Well I realized lights aren't doing the best for me anymore with prices and want my burm to have a better life without lights at night. He's about 3ft long and in a 48" x 18" x 24" but im in the process of building a bigger one. Ambient Temps of the room range from mid 70s to low 80s. What wattage CHE should I use for now and what should I use in his future 8x4x4?
