in all honesty not to sure what the temps are i know its nice and warm during the day than chillier at night... should i put my fan in there yet or wait awhile?
Yes.
Add fan, and if you think it could possibly be getting too warm during the day, or too cold at night, run your lights at night.
I do that, and eliminate the need for a heater, but still have my fan going all the time anyway.
Try and keep temps (at plant canopy level,) between 60 and 85.
Any cooler than that, could possibly slow growth, and hotter than that will give you fluffy buds.
BTW, that pic looks like you're running mixed spectrum, meaning a 2700k and it looks like a 5000k or 6500k in the back.
Is that right?
