hi! you need to oxygenate the water in someway. the airpump is the easiest way to do it. You can add a timer so it's not on 24/7.

Hi! :) nice work. Of course I don't mind if you share a Instructable with the community! :) I'm proud that I managed to inspire someone to actually make one. (your lettuces look good by the way. I tried my system with lettuces before and it worked just fine. You will be surprised how fast those babies will grow!)

I'm not really a specialist but I think they are not mandatory, specially if your system is not airtight. Mine was not airtight (yet close) and the day my pump failed was the day my plants deliver their soul to plant heaven... maybe because I had 3 large plants fighting for air and nutrients in a near airtight container. the roots started to rot and i failed to bring them back to life. It was in the middle of the summer and here in Lisbon it can get insanely hot.. Heat + Black container + broken pump = perfect storm...BTW: I read somewhere that DWC without airstones work better with non fruiting plants. Therefore my advise is: buy a cheap pump just to stay on the safe side. they are pretty quiet and the power consumption is very low. if it bothers you, buy a timer so wit turns off from...
