Putting together the fittings list, can you guys check it over make sure I'm not forgetting anything or that my math is horribly wrong? Also do I need O-rings?

36x Female Adapter NPTF Polypro - 1/4 x 1/8 NPTF adapters for the misters
18x Union Tee Polypro - 1/4 going to run 2 misters per solenoid
18x Male Connector NPTF Polypro - 1/4 x 1/4 NPTF connects from solenoid out to misters
18x Solenoid
18x Male Connector NPTF Polypro - 3/8 x 1/4 NPTF connects from 3/8 feedline to solenoid
25x Union Tee Polypro - 3/8, 16 for connecting feed line 7 for routing near pump/tank 2 spares
15x Union Elbow Polypro - 3/8. 6 for connecting feed lines, 8 for near pumps, 1 spare
10x Shut-Off Valve-Polypro Straight - 3/8 Tube x 3/8 Tube, 8 with 1 for each 8 ft section of pipe, 1 for shutoff at the tank, 1 spare
2x Male Connector NPTF Polypro - 3/8 x 1/2 NPTF connects to each side of relief valve although one side needs a brass female to female coupling.
2x Female Adapter NPTF Polypro - 3/8 x 1/4 NPTF for connecting gagues
1x Male Connector NPTF Polypro - 3/8 x 3/8 NPTF for connecting pressure switch

Whee were getting into the thick of it now!

Thats a shopping list and a half :)
Can you draw a pic of your planned plumbing layout as it would help visualise where everything is going. I cant find any details for your chamber sizes or the type of nozzles you will be using.

I'll be ordering 42 of the CC-214 red nozzles from http://www.kesscience.com/nozzles/nozzles.html (42 is the minimum) unless you have a better suggestion?

If you want to pm me your email address I can scan this drawing and email it to you but the basic layout is 4 rows of 16 ft 5"x5" vinyl posts with 16 plants in each row. 8 misters per row. 1 solenoid for every 2 misters with 3/8th feed line running to each solenoid.

a final 8ft post may be added later so I'm buying extra connections now in case we incorporate it.

ahh.. i didnt realise you were using posts.
I`d be tempted to reduce the number of solenoids to one per post as the cost outweighs the benefits with the limited space. The main problem will be mist hitting the opposite wall and converting back into liquid before it gets a chance to spread out, 5" isnt very far.

I can always take the posts back to the store. what kind of containers do you like for an HPA system?

It depends on the pattern and throw distance of the nozzles but usually the bigger the better. One large chamber is better than a lot of small ones.

Using your posts as a guide to plant size, 6 sites per tub, 4 nozzles (0.9gph) for flow but you may need 6 for coverage depending on the pattern and throw.

Nozzles are always the biggest variable because you never know what they`re going to do until you hook one up and test it at your normal operating pressure.
After testing you`ll have a good idea of where to position them to get full coverage.

Doubling the number of nozzles for coverage means halving the misting time to maintain the same liquid flow.

Hey BobS, the filters are no use on ro waste water, which was prefiltered using carbon. all that carbon does has been done. Nice to see you rockin it to the next level.

Just ordered two, thanks............maybe I'll see if I can use those carbon filters as a pseudo RO system, because I'm going to be using a lot of water and would hate to waste that much RO wastewater down the drain.

EDIT: So John, since I'm planning on running from 100-125PSI, I would just need to precharge the tank to 98PSI, correct? And that's a one time thing, and can be done before anything else is hooked up, correct?

Asking because I'd rather just take it to a gas station (a petrol station, as you'd call it) and fill it up there with a mechanical air pump (which obviously also has a pressure gauge on it).

Probably cost $.75 vs. finding a pump and air pressure gauge.

Yeah, three seconds is way too long.

So JG, just to double-check before I do it - since I'm planning on running from 100-125PSI, I want to precharge my expansion tank (the air part) to 98PSI, correct?
Didn't Tree say his feed times were like 30 seconds with 30 minute pauses? I do think this depends on root chamber volume. I increased my feed cycle time to 3 seconds over a week ago and all is going well, but I am not using an accum. If I did, probably less than one second feeds.

On Pod Racers journal (IC) these guys were building their own pods, which makes $$$$ sense as even 30G garbage cans have gotten expensive, and you need something tallish. The most important component to be solid is the frame supporting the top and the top has to be strong enough to handle the load you will be putting on it. hth

And Jk in earlier posts u were saying with Hp system hardest part is the root growth being so fast and so much what are you and anyone else who wants to add..using as root chambers? Seen the 5 gal pals seem to fill rite up. Anyone doing any crazy PVC customs? Just wondering what's good what's not. I'm thinking a PVC would be nice but thinking it has to be big, thanks guys the more I know less I can f-up or at least not as bad

Since adding a 6" net pot filled with lava rock (attracts microbes) inside a paint filter, plus incorporating an inline 200 mesh (cleanable) filter and switching to DM Gold nutes, more clogging is a non issue.

My sys is like a Morgan,while the HP is like a racehorse. Mine is low maintenance,misters rarely clog, I can get to and treat my root system. 36 gal is a med size tank but huge for hp allowing me more root space. JK

Edit:That and I only know 2 who have stayed with HP that long.

I have come by HPA or TAG by considering their argument (and NASAs) what is most efficient feeding system for roots. Addressing that will automatically pay dividends in the plants. The missing link between HPA or TAG is root hairs.

First step to being on to it is when all your roots have lateral roots and finally when each of these lateral roots is loaded with fuzzies (commonly referred to as root hairs). DWC will never do this, so even though some people get excellent results with DWC, to me it leaves a lot on the table.

Hi Bobby

Very fair response and answer. One big big problem, however, is in real world practice, DWC/RDWC produces the most impressive buds by far that I have seen.

There is a thread on another cannabis site, I wont post it due to respect for this forum, but the thread title is "Heaths latest tree grow" ... by Heath Robinson.

Heath uses no chillers, no air pumps, and aerates his water completely by just water movement and a spray type feeder, and his plant literally is breaking apart with buds and he got nearly 3 lbs off 1 plant if i remember!

I know aero on paper sounds good, however I'm struggling to remember seeing a really impressive aeroponics grow. As far as saving water, thats fine but water is low cost so not a huge issue. Nutrient savings can save some cost, which is good, and D2W is really my favorite reason for getting into aeroponics (yes, I am doing an aero setup now), however I feel like a lot of the reasons people use aeroponics is just to site some NASA study, or to show off root pictures. Most of us are here for maximum BUD yield, and for that I've been really impressed with RDWC pumping out some major performers.

Anyways, I am still planning to use aero, however I think there has to be some impressive aero grows before it can start living up to its name more.

Nah, you misunderstood - I have an RO filter, but bought those filters instead so see if they would/could get rid of the calcium carbonate.

If they can, then I'm gonna get that water analyzed and start custom-mixing my own nutes to my filtered water.

"Didn't Tree say his feed times were like 30 seconds with 30 minute pauses? I do think this depends on root chamber volume. I increased my feed cycle time to 3 seconds over a week ago and all is going well, but I am not using an accum. If I did, probably less than one second feeds. "

I believe he was seconds on / 10 minutes off.

"On Pod Racers journal (IC) these guys were building their own pods, which makes $$$$ sense as even 30G garbage cans have gotten expensive, and you need something tallish."

TF's new pod is only 2' high and is designed for 3-4 pound trees, so height may not be as big of an issue as everyone thinks (if other things are put into place to help the roots out).

I have a drainage question. I know I can put a fine screen on the bottom and drain that way.

I was wondering what people thought about puting drain on the side 1-2 inches up and put chunky perlite or maybe even growstones in the bottom. This seems to be effective for hempy buckets. My thought is that this would allow the longest roots to get extra water if needed and also buffer the system a little. I am planning on growing so called trees and I would like there to be a buffer in case they wanted extra water.

I could hook a hose and flood the through the drain once or twice a week. Kind of like people with hempy buckets do when they flood the buckets.

Also if this is a good idea. Were is the best place to buy perlite in bulk?

I found a person who is using big utility sinks for his aero system. All linked together running off a Big Leader pump. Will try and find the pic.

Hello bro,

I wan't to build an hp aero system that can carry 300 plants SOG style under 2 Adjust-A-Wing reflectors. Will do my homework and come up here again. Very Very Very good thread.

Btw another question about the misting time. I read somewhere that the faster your roots dry, the more they are able to take in the next burst. So under 1 sec on and 3-5 min off was something i was told. 10 people have 10 different opinions on that one.

Well few more months and I'm going to start construction. How is everyone else doing? I know alot were building there systems a few months ago they up and running?

nuttso: Times vary due to pod volume, room temps, RH inside the pod, type of mist heads, pump psi, and capability of the timer itself. I use comparable timer, mist heads and pumps to those using an accumulator, so I mimic their wet/dry cycles.

Due to room staying in the high 80s I increased wet cycle from one to two seconds, and increased my dry cycle to 2:05 and monitoring. During winter I probably can do one second/~3 minutes

Hpa &Aa

Hi all great thread and, great info. IMO AA could be slightly better than HPA as with AA FRESH AIR is introduced every time the plants are misted, meaning extra oxygen for the roots. I wdon't know this for a fact but I eventually would like to build both. Currently on the process of collecting parts for mainly Hpa but have bought some air atomising nozzles as were cheap on ebay. John what nozzles sure you using on your aa system and have you had out up and running? Be interesting to know what you think is best as you've run n built hpa and were in. the process of building aa. Any info on the aa would be great.
Hope to get the hpa finished first. In reality.i roll probably end up using parts off the hpa to complete the aa system.
Cheers again for all the info and input everyone has contributed, mad eR:hie things alot easier.
