Thermostat with timer

hi all this is my first post/topic and grow so please bear with my ignorance ,I am trying without much success to control the temps in my growroom which is a 4x4ft curtained off section of an 8x10ft room,i have to keep switching off my extraction(5" with rhino carbon filter) because the temps get down as low as 14 at night, the nutrient tank is the only thing that keeps the temps at that level as it remains at a steady enough 16-19degs,what I am trying to find is a digital thermostat with timer so I can set an electric heater to heat to 25degs during lights on and about 16degs at night/lights out,i have scoured the net without any succsess so I hope you good people can help.

I would say you need to separate the growing area with something a little more 'positive' than curtains, ie airtight walls. Then your fan/filter will work as intended ; if you use an insulating material for this (like Cellotex / Kingspan) then you will find any heat applied will stay in the area better

thnx for the replys, when I say curtained off what I meant was I have black/white plastic sheeting stapled to the celing that I can roll up and tie off for access this set up is in a purpose built room of 8x10ft that also holds a separate 2x2cupboard for the mama and the same again for cloning all light tight the room is insulated floors walls and celing with 1" aeroboard.perhaps I should also have said that I don't have a hps yet only cfl and florescent lighting so not much heat there. I think that maybe I should get two heaters and two timers and two thermostats, one for daytime temps and one for night , this seems a waste to me which is why im looking for one digital thermostat with in built timer that could the same job but with one heater.
