Hmm... in the grow I was talking about it was drain to waste hand watered pro mix. Perhaps then why we vented? I hadn't thought about hydro vs. Soil/peat in this debate.

And Joe, I'm not saying that I'm right. I'm just stating how it was done where I worked. I never asked why... I just figured that's how it was always done.

Stagnant air = non fresh. To vent your house you open the windows during a breeze on opposite sides so all the fresh air blows through getting rid of all the stale stagnant air. Like during winter after your house has been closed up a while on a nice sunny day you open all the windows and air it...
The rooms were vented right before the lights came on. As far as the controls went we had a huge environmental control panel. When venting during lights on the co2 would turn off. It was crazy how fast the ppms went back up after the vents closed. Huge hissing sound as the co2 pumped back into...
Fletch is right. I worked at an industrial medicinal grow and yes the venting was on timers. I can't remember the exact times that the rooms were vented a day, several times during lights on. And they were always vented for longer periods right at lights on and lights off to fully vent the...
You'd deffinatly have to side light it. Unless you have huge lights the real effective penetration through the canopy is 12 to 16 inches usually. Again depending on size of the lights and that's with hid, CFLs have even worse penetration. You're not going to get good growth at the bottom if you...
Thanks cdd10. That worked. I have pics again. But I don't feel like having to reinstall an app I paid for all the time. So if the issue could be fixed that would be great.
Motorola razorx. Paid app. All the pics always worked until 2 days ago. Now I see none. I've turned my phone on and off. Logged in and out. Didn't help
I use 1/8 milk water ratio for PM control. It works well (it does prematurely redden hairs in flower), but yes it leaves a film. I hit mine with a little high pH water (which also keeps down pm) in between treatments to rinse them, but... don't let that water sit on them or your inviting more...
