That's funny I used to be an electrician as well. I have one of those cheap aqua air pumps and it seems sorta loud no matter if I hang it, put it on a mouse pad, etc.
The more you grow, at least for me, the more you figure out what works for you and what doesn't. I've learned several hard lessons over the last year or so and I'm finally starting to feel somewhat confident about growing these plants. Don't get me wrong, I still have doubts and I'm still learning but I think I'm getting the big picture about how the nutes interact with the different stages of the plants life cycle.
Well, anyways, hydro DWC has been my least troublesome time so far. I mixed a res every Monday and just watched the levels and trained the plant.
