What's too high? Lets say, ~80-85 ambient. :-( end veg/entire flower If you go to the original post with pic's you can see my set up as it runs, with the pump dialed in @50 psi. (max) With the accu tank the pressure drops to ~25 psi before the pump kicks in, so there's a pretty large...

No worries. And you're right. This is why I'm steering towards a 100 psi set-up. Basically what I was trying to get across with this thread is that it is not nearly as complicated or impossible as some would like you to believe, but if one wants to run hi pressure, it can not be done with...

Your points are duly noted and you are correct sir. As I am not running (yet) at pressure high enough to create that elusive mist, I probably am overwatering in one way or another. Going to take my system to the next level (100+psi) literally, will be an interesting and challenging experience...

Yep. Theory. When I look around all I see is theory. I did not invent nor reinvent the wheel. I simply do what experienced plummers tell me to do. Hence accumulator tank. To each their own. This is what works for me. I'm happy with my set-up, you must be with yours. Just keep in mind how long it...

OK KIDS: SHURFLO high pressure on demand pump. Has pressure switch, keeps accu tank at 45-50 psi. High pressure, meaning you must run it at 40 psi or larger. Drawing directly from nute res. Return (run-off) gets pumped back w. small aquarium pups, one for each rack. Mist spray nozzles...

Only use foodgrade stuff. Everything else has junk that will harm your plants. Seriously. Will cost about $46.00/Gal These guys are excellent to deal with. http://www.dfwx.com/h2o2.html Use 2-5 ml/gal - so 1 gal of H2O2 will last forever. Good luck.

Depending on the size of your system you obviously can run w.out a tank. However, it will reduce wear, and it will maintain that working pressure in your line at all times, without any lag time. Considering the goal is to provide a fine mist, I find that crucial. When one has to push a bunch of...

Please keep in mind - we are talking MISTING hi-pressure aeroponics, 40-5- psi. The system I am presenting you with is what I found to work best, for me. I highly recommend doing whatever it takes to make improvements, however some things you don't want to deviate from, it cost me considerable...

It's a Stinkbud with a fogger added. A foggy stinker...stinky fogger.............. finky stogger.....stonky figger....HIHIHIHI.....

Did you add PK13/14 at begin of flower? If not, give it a whirl. From what you describe that might do the trick.

This is my first aero set-up, designed by myself from scratch, and after losing my mind a few times and refusing to quit, finally getting it running like clockwork. Through trial and error I derived to a 4 (vertical) posts x 2 rows per "rack"-system, and run them in what I call 9/3 cycle (9...

Ok - got it - we'll see where it continues. Was wondering. I'll just reply wherever it hits. Thanks.

Was going to continue in Aerogarden, but we'll keep it right here.

Started a thread elsewhere, https://www.rollitup.org/hydroponics-aeroponics/367969-real-world-hi-pressure-aeroponics.html but realized this subchapter would be a more appropriate location. So we'll continue here. Am running H.P Aero system. See pictures. Any questions?

Please ask - that's what this is for. I am using shurflo 2088 594 144 diaphragm pumps. Available on ebay - item #320547297109. This pumps is designed for agriculture irrigation. Paid $80 for it, they go list for about 140 or so. (These guys on Ebay have the best deal. Their service is amazing...

The accumulator tank is rated up to 100 psi, but my system is maintained at ~45 psi by the on-demand pump. Yaaaaaah..... relief valve........ figured w. that kinda pressure dont really need one. But that's just me. Or maybe I forgot, and I am just talking out of my ass.....;-) If you want to...

Can't help but being amused by all the assumptions spouted and armchair QB'ing when it comes to high pressure aeroponics. Reading the TAG thread makes for interesting read - a good amount of chuckles included.(Focusing on one part (H.P. nutrient supply) and ignoring all else -light....!?- does...

Thanks. This pretty much describes the system Steve from Cloudtops suggested to me, with a few variations. I kinda liked quentins' approach, but it seems a little complicated. When you work with accu tanks, it's a whole different deal, and it requires different thinking. So what if you...

Looking at this system while having superior nutrient delivery, the obvious negative difference is "vulnerability". The cost issue is not that big, agreed, since existing gear can easily be retro-fitted BUT: If your one pump craps out, you're running on whatever residual pressure you've got...
