Okay, thanks guys. I know more bubbles is better for creating that semi-aeroponic environment above the water. Illegal Smile, you even repped me recently, "I wish more newbies would get this simple fact."
I've swapped out three pumps so far for my first 5 gallon DWC, each one larger then the previous, and I've seen faster root growth each time I replaced a smaller one with a larger. Now I'm ready to fully commit to all DWC grows. This means I need more/bigger buckets. But before I pick a pump I was curious to know if there was a point where more bubbles gave diminishing returns. I've seen what minimal bubble action does, was looking to find a magic number for as little as 10 gallons of water and up to 60 gallons of water. So far I like how 1LPM of air per gallon of res performs, but wasn't sure if I should go higher.
IS, thanks for the link. How many gallons of res do you use that one pump for? Here's
another pump (60LPM) I was considering. Would probably use this for 60 gallons of res, but maybe I'd use yours (~38.5LMP) if I only have about 30-40 gallons of res. I plan to use 12" air strips and/or bubble walls because I've noticed these work best for me. Does that sound good?
