For this it would be nice to have one of those 'frigs from a grocery store!
They have lighting fixtures in them.
However that is not possible, so I am thinking to wait until the weather is cool , but above freezing during the day. Then move the plants back and forth from house. And move under lights at night.
A greenhouse might work depending on weather too , but here would not give long day lighting. I want to try growing Laurentia ( Isotoma axillaris) , but to get good flowering it requires chilling and long day lengths. I am not trying for Florist quality plants---jut reasonably good flowering. What thoughts has anyone else on this?
