newb, what are your water temps in your buckets? are you running a chiller? Try to keep them under 70, Or you could go 8 weeks and come down with pythium and kill your whole grow. Just think, you might be blowing hot air from your grow room through your air pump and blowing hot bubbles into your water. What I used to do with your type of setup is put your air pump in a cheap cooler,add some frozen bottles of water. Then you would be blowing in cool air instead of hot air. Goodluck
