I found netafim nozzles, but how can I mount them to my 1/4" flex tubing? I don't see any info that indicates it is possible. just a 1/2" pvc adapter. http://www.greenhousemegastore.com/product/netafim-fogger-assembly/misting-heads

I saw a great page that also says you should put half your potassium nitrate in A and half in B because it is the limiting factor as far as how concentrated you can make a stock solution. I can't find the link at the moment though, need to find my phone.

So if you keep them separate(part A and B) and only mix in the reservoir, there wouldn't be any reaction(precipitation)? My main question is can you dial down one of the ingredients independently, or do you need to worry about keeping ratios proper for a reaction to take place...

Are there any reactions that take place, or is it just mixing salts?

Can you share what you use, maybe by pm? I guess if you won't put it on here publicly, then you'd have no reason to give it me. If you can't share recipe, could you at least share target ppm of all the diff elements? I feel like an archeologist, combing through ancient dusty books found in a cave.

I'm pretty sure Fatman's formulas were for 100x concentration, but in the original thread, he said he would never use them that strong, and suggested diluting to 200x to 300x for actual use in aero.

Ya hago nozzles are made for combustion chambers, so they engineered the internals to increase exit velocity so can rapidly disperse/fill volume. I will look into mounting them horizontally, half way up, but that may require too much tubing/pressure loss since I'm using 1/4 line and 100 psi...

Sorry about all the quotes from previous threads. I'm just trying to get all this stuff in one place, for me and the next noob. So do the roots need support beyond what you mount them to the lid with? I thought you could just use a rubber-like conical plug(like rapid rooters?) with the...

Ya, their sales team is useless. Second set-up look ok? If you fix the typo, seems like the flow rates are the same on paper, I must do a test then. Regardless, the second set filled the chamber much better, and threw the mist much further.

woah, finally got the datasheet from aeromist.com(they don't provide details besides "atomization") while the droplet size is, 43um, the flowrate is .02 GPH. Lol WHAT! Everything ive heard on here is closer to 1 -5 GPH. I had some 1 GPH nozzles lying around. I didn't want to use them because...

Also, too bad Fatman7574 is extinct, does continuous, or long duration work(like 10 -30 sec)?

My first clones dried to a crisp. Hopefully this thread can turn into a how to if yall have good input. Here is what the size of the clones/root at start: I feel like my chamber had good mist amount, but since the clones roots are so small, perhaps not enough surface area for them anyways...

I would buy an exact copy of your system, but I can't find any USA suppliers that sell your stuff. Seriously, I cannot find your Netafim nozzles, and I really want to take your advice on those.

The switch was made by aquatec, 60PSI to 80 PSI Adjuistable +/- 20. I actually solved the problem. I did not realize the aquatec 6800 had a pressure adjustment on it. Cranked it clockwise a few times with an allen wrench. Now it's up to 95 PSI at shutoff( tank max workin pressure is 100PSI. I...

I just started my first grow in my HPA system.(aquatec 6800 > pressure switch > tank > solenoid > nozzles. After 24 hours, the pump started running continuously. No clogs existed, tank still pressurized after I emptied it to check. During testing, the system ran fine, requiring only a minute on...

Do I need to be able to feel droplets if I put my hand where a root site should be? Or is the raised humidity in the chamber enough? I don't feel any mist in the corners. I think I may need to go with higher flow nozzles, the spray is just not filling the entire container. I tried other...

No, like, I have no idea what you mean by that. Are you talking about for a root chamber? Btw, you should read this entire thread https://www.rollitup.org/t/my-true-hp-aero-plug-play-pods.254876/

Can you elaborate on "rails vs 4 inch pipe"
