Fog Timer?

[Prodaytrader]

I have been reading a while now about timing. I have seen threads suggest that 24 hours of fog is ok and I have seen threads saying 1 minute on, 3 off, and finally 10 to 15 seconds every 30 minutes. The later, I can't image even being possible but between the first two, which is better? Should I even use a timer at all and just leave it on? Maybe 1 minute on, 3 off isn't so bad. In my case I cant seem to find a 3 minute mark but 2.5 minutes is working on my time. So for now I have the timer set to 1 min on and 2.5 min off. I see video's online of people who use no timer though. What gives?

While I'm at it, I have heard I should reduce my nutes. Can anyone say for sure? As in, anyone here use a single chamber 3 head aeromist setup and can tell me what strength nutes do I use and how long do I fog for? thx

Isn't there a way to edit my post? At any rate, I was just at the hydro store and the "expert" "who probably doesn't grow at all, right???) said that I needed to set the timer for 1/10, 2/20, or 3/30. That sure seems like a long stretch every 30 minutes. Comments?

First off, not all fog is created equal. Depending on the size of the droplets in the fog, that will determine time it needs to cycle. I'm currently setting up a aero/fog grow tray that uses two sources of mist or fog. One system is based on a high pressure pump (180psi) and mister nozzles, this produces some 5 micron droplets but the bulk is at 50 microns or more. It will run the tray with just 8-10 seconds run per 1/2hr. The other system is based on an ultrasonic fogger (FrapaPlas) that produces mostly 5 micron fog (dry fog). This system will run the tray with abt 10 min on and 15 min off.

In my setup, I use the ultrasonic on a 24hr schedule (but plain RO water during lights out) and the pressure nozzles only while lights are on.

Since you are using a "pond fogger" based fog generator, you want to run nutrients that will not clog the transducers. Humbolt Master is supposed to be clean running in pond foggers, tho I have been using Dutch Master's Advance with success so far. But the ultrasonic fogger I'm using is not as sensitive as a pond fogger, plus it gets a cleaning every lights out by using no nutes, just RO water, and that helps keep it clean.

A good starting point for nutes in fog is a 40% solution. This is based on most feeding schedules for hand watering that suggest full strenght nutes, followed by just water twice. Since you are feeding constantly a weaker solution is going to be needed, hence the 40% starting place.

Hope this might help you. :thumbsup: Good luck and good fog growing.
