KiYou can use any kind of pump and hook it up to noogleberry cups.  I've used a food saver hand vacuum pump and the vacuum system in my car.   I'm not a fan of pump and release.   I like to keep them on for hours at a time.   Figure exposure hours are exposure hours and the more you get exposed the more growth.   IMHO.

Karren, with keeping them on for hours don't you feel like pain after the session? When I do 1h straight next hours I feel like I am going to die, and I don't use the highest pressure ...
