I don't care about sound, I'm in a legal spot and my grow isn't in my bedroom.
Check the wattage consumption vs output on that style pump and also the fact that the air leaving the pump is hot as fuck.
I have some of those type pumps too
I see, that makes. most of what ive seen against air pumps has been about noise level.
I actually keep them outside the tent and have fairly long leads on them and have not noticed a hot output on them. I have a good chiller anyway.
Guess my main concern was cost vs output to start up.
The pump I linked is 110 lpm and the GH ones are 20 lpm
The GH ones advertise as 320 GPH if you do the conversion, the ones I linked are 1700 GPH.
Id need 12 $65 GH pumps to replace the 2 $70 pumps I use now.
