Use deluge scheduler to seed when you're asleep and you don't need bandwidth!

Deluge has this nice plugin called scheduler that let's you program at which time the torrents should download/seed, if you have a small homeserver on something such as a raspberry pi you can just schedule deluge to work when you're asleep, this way you can seed/download while not impacting your bandwidth when you need it, very useful to really slow connections (like mine).

This way you can keep seeding for months without even noticing!
