Luffa belong to the curcubit family, so you can follow advice for growing zucchini or pumpkins

I've seen YouTube videos with 2 types of loofah. The one with ridges, and a much larger one without ridges. I live in Natal and want seeds for the much larger type. Please advise where I can get these seeds.

23 Mar 19, Can you ripen or dry luffah off the vine (Canada - Zone 6b Temperate Warm Summer climate)
At the end of last summer I had luffa's that were over a foot long but didn't know how to dry them. We were coming into frost season and I thought they would rot of the vine if not picked. Well they rotted off the vine also.
