I grew loofhas this year and has success. But my question is...I have some very large loofahs that seem to just get bigger and then I have some that (to me) are small and are turning yellow. I can't find a good answer as to know when to pick them. Any advise? I can't let them dry on vine because it's getting down in the mid 30's already
