Can I put my gherkin plant in the blowaway greenhouse already?

The allegedly "compact" plant is taking over the windowsill and is now flowering. Do I dare to risk it in the blowaway greenhouse already?

The temperature in the b.a.g.h. is between 5-25 c and it seems that we are into fairly stable temperatures now.

I only have one potful (found some old seeds) so wouldn't like to lose it. This is about similar variety Wilko's gherkin seeds

Thanks!

 

My Cucumbers are getting the same Selleri, I'll wait a couple of weeks and then they go into the blowaway house.
