alrighty I just ordered that 400w hps/mh lamp, and an industrial air pump that pushes out 75L per minute... that will give me bubbles for all of my DWC that I will have set up. I just need to get some bigger air stones for all of them... I might just run straight air from the tube and tie it down to the bottom of the net pots for now untill I can get the stones... I should recieve these items late this coming week. EXCITED!
