i don't have any indoor grow at the moment. i am in the process of gettting all the equipment for a 1kw hps cooltube scrog grow which i will start when my probation is over in a few months. my outdoor grows were ok. one of the sites did well but someone found my 6 best plants at the second site and stole them the day before i was gonna harvest! i'm glad the bubbler works well for you.
