yes
you got it
Even though tents used are well made I know
Vapour transmission is impossible to stop as such
without 100% sealed vapour barrier like the bubble boy lol
I keep it cool and low humidity year round in tent area so that will help me.
Have all the toys but still need to look into few things.
Anyone comment of best water pump, adjustable output, low noise, low heat transfer?
300GPH up to say 1000GPH but not set in stone.
Been looking at Danners mag drive ceramic impeller units.
I have a 4 port air pump of theirs.
For price it is great but I will need to upgrade now.
Anyone have a good quiet but powerful air pump that does not heat air up?
Gotta be able to aerate say one 5 gallon pail easily at low power but yet do 6 or more 5 gallons pails if needed in total water GPH.
Also methods others to use to cool water without big chillers(other than waterfall which I can't do here)
I know they are some other tech just can't remember name.
Likely linear pump is the best way to go I understand for air pump.
Adjustable output is a must for me.
I wouldn't use any restrictors on a pump. They'll put the pump under load and cause it to heat up, which will also warm up your water. Just get a 1000gph pump, if that's the size you ultimately want. I think you'd be just fine with a 400gph pump, since you're only going to use it to circulate the water, and not run an under current system. I use a cheap 400gph pump for my 60-gallon RDWC. Run the pump inline to help keep temps down. Danners are great, but expensive. I just get the cheap ones, and keep an extra on hand.
My pump
Instead of a single pump that may, or may not, power several sites, you'd be much better off getting small individual pumps. These are great...

You're not going to be able to get away from noise. A better approach might be to soundproof the room. It's pretty easy. A few simple things make a huge impact. I have mine soundproofed because I mix and record at home, right across the hall. When I close the grow room door, it's virtually silent. And I use a commercial 70lpm water pump, three inline fans, and several other noisy components. I describe how to treat your room in my thread...
Soundproofing
I'm able to keep my water temps at 68, without a chiller, or any other cooler. Again, check out my thread to see how I simply use my house air to maintain water temps. Go half way down the page...
