How will low night timps affect growth rates

[Newgrow31]

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.

Any use putting a rad in there or not really Aby point

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.

I'll get the rad out and put it in then cheers

Sorry, thought this was an outdoor grow.

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.
