Rothschildianum growth

[kiwi]

I have set my glasshouse to be a minimum of 18 degrees celcius through the coming winter. At this temperature will roths continue to grow? Daytime should reach early twenties.
Thanks kindly

You could go down to 14 celsius and they would still grow..maybe lower for short periods. But also will depend a lot on how much light they get

So Roth's tolerate cooler temps? Do cooler temps, help to initiate bud set?

some people think so

Day length will be the rate limiting step in NZ. That temp should be fine though they will be slow over winter anyway.

Your minimum temp is fine. If you could increase your maximum temp by another 5oC or so, you will be better off. I would live in as cold, if not colder, climate than you and I can get my greenhouse up to the high 20's in winter. You just need the greenhouse in a good sunny position.
