Luffa seed is the seed of the Luffa plant, which is a genus of subtropical and tropical vines in the cucumber family. Luffa seeds can be used to grow the plant, which produces fruits that can be eaten when young or left to mature and dry on the vine to create sustainable compostable sponges. The seeds should be soaked for 24 hours before planting and sown 8 to 12 inches apart along a fence as soon as the ground is warm enough to work. It takes 120-200 days for the plant to fully mature from seed.
