Rothschildianum low temperatures

[kiwi]

Hi all,

Well it is spring here and temperatures are starting to warm up. I have been growing my roths, sandies and mastersianums under lights at a constant heat of approximately 20 Celsius through winter. I was wanting to put them all outside in my glasshouse but night temperatures are still getting down to 7-8 Celsius. Day temperatures in glasshouse are in the mid-high twenties.

Will putting these outside now be detrimental to their growth? Or will they just stall for a while until the night temps start to increase?

Thanks in advance

I believe they will stop growing at that temperature

They grow in malaysia on sarawak peninsula at roughly 1800 feet elevation, I would google that and adjust my temps accordingly, I grow mine winter night 60 -65 day 75 - 78 it is growing very well my summer temps are 90 day 70 night

I think 7-8 is too low. Mine have winter range of 13-15 to 24 with a rare drop overnight to 10-12 and have continued to grow but more slowly. I have mine in clear pots so i can see root activity. They never stopped.

Rothschildianum will never see temperatures of 7-8 degrees C in the wild. I have stayed at the base of Mt Kinabalu before, at the small town of Kundasang, and the temperature will drop from 23-24 to 15-18 in the early morning for 5-6 hours. Here's the link to my thread but the photobucket links are broken, sorry.

Yes, I agree that 7-8 degrees is a bit cool, especially if they are small seedlings. My roths grow in a heated glasshouse set at a minimum of 15 to 16 degrees.
