outdoor greenhouse for winter hoya growing
I am considering purchasing one of those temporary walk-in greenhouses to house my orchids and hoyas in over the winter.
I live in one of the chillier parts of brisbane and had several nights which got to below 5 degrees celcius last year (below 40F), which resulted in losing about 7 different hoyas from the cold.
We usually dont get nights below 5 degrees. The days are always warm and sunny, average of 23 degrees (around 75F) so its not the daytime temps I am worried about. Our winters are usually quite dry.
Sunny winter window space is a premium - so bringing all the warmer and intermediate temperature ones inside is not really feasible. Im thinking whether an outdoor greenhouse would provide a suitable humid and warmer night environment for my hoyas.
I know a lot of you grow hoyas in much much colder climes than mine - so hopefully have some experience with an outdoor greenhouse.
your thoughts are appreciated.
