Thanks jeeba, I appreciate it.

??? My nozzles will not work without the addition of air into the chambers. They utilize air pressures between 30-60 PSI and fluid pressures between 40-70. I don't need to source a separate supply of atmospheric air to feed my chambers O2.

Maybe I Am missing something. I thought you had a separate tank for air + HPA pump. No?

I have an air compressor tank mounted to an oil less compressor which supplies compressed air to one side of my nozzle. My nozzle also requires compressed liquid which is supplied by my fluid pump and accumulator and runs into the opposite side of the same nozzle. This is repeated with all nozzles so that each has its separate fluid and air supplies.

PF- it's Atomized aero (AA) like G-love's Atomix setup - Atomizer and tree farmer also got into it. Did all that fly right by you somehow?

Last I recall, AJ was having problems with dry roots, presumably from too my AIR mixed into the AA misting cycles, hence my query.

aerojunkie · Feb 3, 2012

I think I actually need more nozzles in that larger chamber because by the time the mist got to the roots it had become more of a fog rather than the appropriate sized droplets. I am going to try a few different things. The plants in the smaller clone chamber are doing fine although the timing and duration need to be dialed in.

Well, I'm curiously awaiting the answers with you. I do plan to tryout AA someday, and would like to learn from your experience here.

As I mentioned, when I called Hanna tech support, he told me they only last ~ 1 year. I am careful to keep the tip wet, but did not calibrate very often. Fail, it will. Perhaps frequent calibration once it is > 8 months old will be an indicator

DIYer, I watched the mist while turning the screw, so yes, it worked on my 8800

1st of all, you get what you pay for. Hanna instruments are cheap. Pick up a Ti-Meter and calibration solution and calibrate it @ every res change....it will make life much easier and will pay for itself in the headaches endured in PH and PPM issues.

I ended up with a hanna all in one that I'm pretty happy with, but I always wanted a Truncheon. I will also look into these as well- how would you say they compare to BlueLab? I can't find "ti-meter" was it a typo for tri-meter, or would you happen to have a link?

umm, if you don't know how he does it, how do you know he does in fact do it dickherad? id need to see one hell of a grow thread proving that kind of yield from just 1000w

Read threads posted by Professor Marijuana....it is all about environmental control and lighting. Master that, and you will be a master grower.

Sorry man....Tri-meter.....3 in one...PH, PPM, and Temp....they have them all around....about 140 bucks give or take but it is so worth it! It is continuous and the calibration solution is cheap! It helps out so much!

PROF XAVIER · Feb 17, 2012

I have been reading this thread...very good stuff....but why do you need the nozzles to supply the air? Only seconds a minute? Continuous availability to O2 levels seems more adequate...just a thought.

For those who aren't subbed to both threads:

Previous photo taken 1/21.

New photo: It is growing fast. Alas, probably a male, but I have others in the bubbler. Mist cycle 1:5-6.5. Just increased this morning to 2: the Sentinel MDT-1 is not accurate at 1 second setting. Experiencing a bit of spittle after the cycle, though it does not spray.

Root shot was taken right after a mist cycle, so there are some droplets.

You have a young plant there...what is your air temp, humidity level, and co2 level? What is your root zone temp and humidity level?

I believe some oxygen comes out of the water when misting. It's just a guess. Also, when I tried to put a pc fan on my lid to ventilate for heat reasons, my roots started looking like crap in that particular case. Luckily in AJ's case, he is using AA which injects fresh air with each mist pulse. If anything, the amount of o2 you'd need to add to a chamber, could come from something as small as an air-stone, and that's IF it's even necessary. I like tree farmer and Atomizer's roots, and they never added air when they used hydraulic that I know of.

Oxygen can only come from water through the process of electrolysis where a current is put through water to release separate gases of hydrogen and oxygen. If you run air stones and air pumps...your only pumping the air in the room inside the grow chamber...no more and no less.on the same hand, increasing the O2 levels beyond normal atmospheric conditions can have a negative effect on the root zone just as too much CO2 can harm the surface of the leaves through the transpiration process and the photosynthetic process.

The nozzles supplying air are just a byproduct of being air atomizing in their function (to get the proper droplet size and projection). In high pressure aero, the optimum feeding cycle tends to be only a couple seconds or even fractions therof. It's not about timing, but saturation, and due to the flowrates, these timings tend to be what we have to make it work. Been reading the prof's threads- interesting, gees he got alot of controversy though. BTW - my Hanna is a tri... Apparently the professor is either wrong sometimes, or Hannas can be good according to him:

Trying my best to tolerate the haters, so far so good. For meters I use the Hanna ph/ppm/ec meter. Quality product that is durable. The beautiful part of H&G is it eliminates the need for some of the monitoring. Here's how I do it, when I drain every two weeks and feed exactly every 7 days I have found the need to measure ppm is no longer there. Follow the guide and add for the water volume you have, drain regularly, and ppm and salt build up isn't a problem. I measure ph every day, it's critical. If your ph is out of range the plant can't take in the nutes, you can use the best food in the world but if you're ph is off it doesn't matter. Doing a scheduled program eliminates a lot of work and problems. I rarely need to adjust anything, you get in a groove and maintain it. Don't worry about your questions, they're all good if you learn something.

That's sort of what I thought (about electrolysis and enriching 02 @rootzone). Thanks for your insights.

I recommend a Nutri-Dip Tri-Meter (around $225) if you dont wanna pony up the extra $100 bucks for a BlueLab. I had an issue with my first one having a little dimmer temp readout so I called them. Made in Canada and about as nice of people as you can ask for. They sent me a replacement board without me having to send in anything, another set of free ph probe and ppm probe and some free calibration solution. They hooked it up since I had an issue. Had a return label in the box and all. They even sat on the phone with me trying to figure out where I was picking up interference, turned out the digital light balast output cord to the bulb cant be anywhere close to the unit at all. I had to set my balast on top of my tent to fix it. I totally vouch for their tech support guys and customer service!!

Sorry Trichy...late night insomnia...thought everyone was referring to those $30 pens that did either PH or EC/PPM. My bad. I do have the Nutrition Dip and love it. Hasn't failed me yet so just throwing in my 2 cents. Don't mean to come off as controversial either...I'm sorry.
