i need some help please

hey im growing in a greenhouse in england and my plants are about 1/4 way through flowering. Is the frost going to harm them or does a greenhouse kind of protect them?

It helps a lot, but you may want to consider some type of heat source. Water with 80 degree water just before it gets dark, that will help a lot. Good luck.

a greenhouse should protect them from frost. and yes frost will kill em.
