So if my temps come down to say 7-8c over night with day time temps being at 27-30c how much will this affect the health and growth rate

No problem. The big swing in temp may slow them down slightly but not enough to worry about it.

In my experience thats way too cold. Last winter my lights off temps were around 11c. The plants stopped growing and started to have nutrient deficiencies.

Some strains can handle cold better than others but I would definitely get those temps up.

Ideally you want to heat it to 20c but I've grown through the winter in an attic and had temps as low as yours with no problems, it does slow it down but nothing drastic ime.
