Should I add more airstones?
Mushyman420started grow question 2 years ago
Do you think I should add more airstones? I got 4 going. I am thinking about adding 2 more on another 15L Active Aqua air pump.

gasses dissolve almost immediately... the content in the water will reach equilibrium with the sorrounding air (in this case a many bubbles + surface contact with air) very quicly. if you ever go with a sepaate reservoi style, go with agitation > bubbles.. it's far more effective for larger volumes... ask any aquarium owner.
i would wager you don't need more for oxygen-related concerns, but if it helps agitate and otherwise avoid a stagnating bucket of water with some filler, then go for it.... if it circulates / shifts around enough as-is then it won't help much.

Yes probably would do RDWC in a future grow. Got the pump that goes to chiller running 24/7. Not true RDWC, but still good circulation. Entire volume of water is circulated 40+ times per hour.

I just lowered the water today to a little below the net pot since I spotted a root. I usually try to aim for 1 Liter of air per minute per gallon of water. At around 16 gallons right now.

I don't know what more airstones would get you, quite frankly - as long as you've got some good bubbles going, that's really all you need - you've probably got MORE airstones than you need ... but it IS a big bucket!
I AM concerned about what you said concerning the water level in your bucket - that it was right at the bottom of the netpot and this isn't good. You need to leave a space of at least 1/2 - 1" between the bottom of the netpot and the water... the roots need that humidity zone and will die without it...
Good luck!
