You could just plug it into a simple timed outlet:

Century 7 Day Heavy Duty Digital Programmable Timer - Dual Outlet (Both Control) https://www.amazon.com/dp/B00MVF16JG/ref=cm_sw_r_cp_api_g-xCzbJF8FB3E

this one is pretty good https://www.amazon.com/gp/product/B00MVF16JG/

I'd stay away from the ones at petsmart/petco there are many reviews of them catching fire
