Has anyone had any luck growing these gourds? My husband's family are Finnish and I wanted to try and grow my own Luffahs for the sauna. Also, has anyone seen seeds for sale nearby? (I live in the Duluth/Cloquet area) I went to order them online, and they are reasonable, until you add in the shipping. My $1.89 seeds go up to $5.00. Call me cheap, but its hard to pay that much for seeds I am not sure I can grow!
