You can get away with 78* IF the humidity is < 60%.
Otherwise you risk root rot
Otherwise you risk root rot
i filter the air being pulled in by my air pump. I made a box - intake air tube goes in one side of the box, one wall of the box is a hepa filter. funk can and will be introduced into your reservoir through the air pump pulling in room air. This helped me immensely - since i have found slime growing out of my airstones.
You're missing the big picture. You did all that for nothing. You don't need airstones
I'll update the thread Before harvest but other than that there's nothing else I can add to this discussion. You do not need air stones period.
I snapped some quick pics before lights came on (I veg 18/6).

You can see how massive the growth is because this is the same girl from my post two days ago.
Here are the roots of a girl closer to my reach

They are pearly white and massive. I never had a root mass this thick this early when running air stones.
Also, I run my water at 72 degrees. My chiller kicks on and takes it down to 70 then it climbs back to 72.

That's another good debate. My hypothesis is all the guys running 65 degree water are doing more harm than good to their roots. The fact that colder water holds more oxygen has everyone focused on that one fact and they forget to ask how cold is too cold for root health. In my hours of googling I came across a post stating they read a scientific study that said 78 degrees was the best root temp but didn't site a reference. we still have to take root rot into consideration since I can only presume that study was soil temperature so I decided to see how close I can get to that optimal 78 degrees without causing root rot in my system. My chiller is running less and my roots are staying white and the growth above and below water is explosive.
I've had several successful runs without them.. No need, esspecially with the waterfall effect in each module...Im all in for pulling up a chair for this thread..love running test and all but before u start telling people they don't need air stones definitively let's get through a whole run without them. When the buckets get full and circulation diminishes oxygen levels get depleted faster you "might" have more issues. I am hoping it is a successful run because I myself hate air stones and air pumps 2. I do like the idea of water fall in each site to add circulation and better aeration.
