True HP Aero For 2011

Accumulator will aid in many ways, so if you're going for optimal yes. The relief is needed, though a fool could avoid it while risking their lives.

I have a more important question, why is everytime I look up swivel branch tee's for john guest they quote it as NPTF but when you see the picture, there's no threadded interior, just what appears to be a very male exterior thread... shouldn't they be labeling these NPTM? This is a major source of confusion here.

Thanks to r0m, I now realize due to the availability of pieces, you want to reduce after the solenoid to 1/4 or before, I'm using a two way divider in my design and they're only available from what I can find in 3/8 so I'll have to use a reducer after that and turn it into 1/4" then to the JOHN GUEST FEMALE ADAPTER(S) where they will become 1/4 off to the SBT which if these pictures is lying and the labeling is right should have a 1/8 NPTF, I'm guessing they don't since r0m didn't go that route.

Howmany pumps do I need for the 3 tents? 2 flowering tents with 6 sites total and 1 veg tent. am I going to need 2 pumps 1 for flowering 1 for veg? cause the nutrients are diff?

I believe the nozzles in those systems are cloudtops. Not sure, but they would certainly work.

I don't think anyone knows what is the "best", the two most commonly used are the Tefen (aka Cloudtops) and the biocontrols. Mike is trying the DIG EXL but as far as I know he is the first to try those.

Tefen are available from cloudtops or dripworks (MNRED @ bottom). You have to call to order the nozzles with check valves from cloudtops.

Biocontrols are available here (Product Line,,,spray jets and misters). If you can order online from their site I can't figure it out.

and for my reservoir and equipment do u guys use hydrogenperoxide? to sterilize where can i get the right one not the over the counter one

I'm using bleach, I believe that TB plans on using it as well. I think I remember Atomizer saying he uses it but that could be a brain fart.

Are you planning on running an accumulator?
If you plan on running different nutes for veg and flower then the minimum number of pumps/systems you would need is two. The pump is part of a larger system. You need to think about the whole system, accumulator size or absence, number of misters, tubing run lengths and diamaters and planned misting times at the very least when designing your system.

thanks for the sites!! should i plan on the accumulator? he sent me a drt-1 timer already set at 1 min on 5 min off I want 6 sites for flowering 3 sites for vegging 2 mister heads per 10 gall site so a total of 19 heads. 1/4 line is what im planning on using. he sent me bc nutrient kit how much do I use for vegging and flowering with this system? and should i be concerned about a screen and something in the reservoir to move around nutrients like an air stone? thanks Rom big help!!

For everyone wondering what I mean by a TAP ADAPTOR

That is the easiest way I've seen to connect to the accumulator and then out of the accumulator straight back to JG

Those times are for LP aero, if you use the 1ml/100l target you need a misting time of ~.18 seconds with two Tefen nozzles and a 10 gallon chamber. That timer has a minimum of 1 second. It will get interesting. The people here tend to like larger chambers (except me) and the short misting times are the reason. Not sure what type of results you'd get with 1 second times but chennemann (see a few pages back) is getting VERY good results @ 1.8 seconds even if he isn't getting the fuzzies.

I'm not sure you would want to go 1/4 all the way if you are going to feed two tents from one res/pressure system. boodadood is a fluid dynamics guy he should be able to give you a better read on how well that would work.

I know nothing about those nutes..

I don't use any air or water pumps in my res but I haven't been running long enough to say for certain that you can do without them. With HP aero you should use highly soluble nutes so you won't need a screen.

That link is to BSP threaded parts, are your Accumulator and PRV BSP or NPT?
I'm only guessing but those puppies look like they are pricey.

ok hopefully hell chime in Ill use the 1/4 one for the veg tent then when it comes time and then do 3/8 for the two flowering tents if needed!

do i need a pressure reducing valve the one u listed isnt on h20hydro site?

This isn't a sure thing you seem like a novice grower, avoid this, this is for advanced growers, not that the concepts involved are advanced, but if you've never grown Cannabis... I don't know if AERO is where you want to start. F&D, RDWC are far more documented. If you hook this thing up thinking you're going to be running to others every time a question comes up, fully expect to waste your time and money and have your crop fail, if it didn't I'd be shocked. that said, best of luck.

The accumulator I was looking at is 3/4 NPTM, but TD says he's learned that BSP and NPT are interchangeable.

I only needed three of them in the entire system, how does that calculate vs. how you got it connected?

Also for those using a chamber desiring or requiring a two way split I've collected a few mfr details

Legris Two Way Divider 1/4" 6340 56 00WP2
DMfit Two Way Divider 1/4" ATWD0404
John Guest Two Way Divider 1/4" PI2308S

I think I have enough detailed to post a layout, so I'll do that tomorrow, maybe it will help people that click really deep in the thread.

Your right I'm not experienced with this. but 99% of succes is failure! So if I fail I'll keep trying till I nail down! I was sold a system from supreme so I'm going to make the best of my investment, or make it better then what he offered.

DH, you got to start somewhere... You'll see that most people here will answer your questions unless they just don't feel like it... In which case, someone else will most likely chime in. Were here to help, but it would still be wise to burrow through as many threads as you can. At least to get a handle on the basics. This will prevent much frustration while keeping a few extra dollars in your pocket.

To each their own, I have never grown in any system other than Aero. Granted my first system was a 6" aerotube nft hybrid, but nevertheless I built that system and was onto hp hydraulic nozzles before it was finished. As of last week I switched out my last hydraulic cloning system to AA and have enjoyed every step of the way. I do not consider myself an advanced gardener, but I do know how to build. Aeroponic technology is the reason I grow. For most of us on these threads, it's just as much about the journey, as it is the destination. If you don't feel like answering someone's question, then don't. No one will hassle you for it. Just keep the arrogant opinions to yourself and don't clutter up this forum by debasing someone else's efforts or desire to join in on the reindeer games. This goes for all the neanderthals out there.

BTW, If anyone is interested in some 12' x 6" aerotubes, Ill cut you a great deal!

thanks AJ i agree the arrogant post and trying to strike fears into others who are just learning aero is nonsense thats why i came to forum to ask questions and learn!
I suffer from OCD and Im loosing sleep reading about this lol my girl is going to shoot me! but theres chronic to be grown!!

I meant no offense if I did not read every post.

Stoner's system is highly overpriced though when I see projects that do proper HPA they all agree on the basic components of the system being the same, the only major differences I see are safety and reliability, as well as capacity changes, sans those the only major is materials choices.

Has anyone tried screening off their roots with a micro mesh to block offending droplets of inappropriate sizes.

By that same token and on another note has anyone tried to use micro mesh to split a jet into the desired droplet sizes at the end of the line instead of micro jets?

I am very interested in this subject and in no ways mean an offense between any parties I've seen these threads die over and die because of that and I will have no part of it, I merely aim to ask questions I believe the answers to have merit for everyone that is interested in this topic.

If I did not mention it before, google mist google, check out their equipment and get back to me on your opinion of it, for this use, they have line rated to 1000 PSI, and stainless steel braided pressure tubing, as well as all the sprayers one would need for a true HPA, but I'd like a second opinion.

maybe u should reread your 3rd paragraph bud!

Hey dickhead (it's funny to call someone that when i'm not pissed at them)... I think you are leaping before you look bro. Stop buying stuff, start reading. While we're here for a support system, we can't answer each question you have right now because you don't even have a clue what you are doing or talking about (yet)... You have to understand the concepts, and what you want your build to be like-then you will know why you might want a PRV and how many solenoids you want. You cannot simply retrofit the "impulse buy" of a system you just got to be a HP-aero and expect to get the same results. All of the components must be thought out to work with each other. eg: So you have a certain chamber size/design? It dictates how you will best tackle the other variables. I'm sorry if you bought that rig based on seeing someone wrote about it here in my thread- had you read more before you bought, you would have learned that advice was from someone still trying to grasp the concepts. The machine will likely grow decent plants, so it's not a total loss, but don't expect it do or be what we're writing about in this thread, nor can you easily add a couple parts and make it work the same. If you want to get that thing up and running- I recommend checking out some traditional aero threads and asking some questions there- then read all the HP-aero threads (lots of work/knowledge) and then you can start designing a hp-aero system from scratch and put it together once you've gotten your money's worth and experience out of the system you already have. Don't worry- the system you have will likely grow nice plants-but it's different than what's in this thread...

Thank you TB, I now realize that if your PRESSURE RELIEF VALVE is 3/4" since BSP and NPT are interchangeable we can simply use the same TAP ADAPTER I've found to hook the ACCUMULATOR into the JOHN GUEST lines.

If I'm correct that you have just simplified the whole process as you can run 3/8 JG all the way up and through the ACCUMULATOR then use a 3/8 JG SWIVEL BRANCH TEE, a line, to the TAP ADAPTER and then directly to the PRESSURE RELIEF VALVE, the TEE would continue to the SOLENOID and onto the final line(s) w/ MISTERS.

That "Tap adaptor" as you call it looks like what I used to connect my nozzles to JG line. Sometimes I don't answer your questions because I can't understand what your asking, but it's not because I'm ignoring you

Click to expand...

As an example to what I just wrote in the last comment to you- there aren't "Best" spray heads, but perhaps spray heads best suited to your particular design. If you have a long chamber, then perhaps you will need sprayers with a narrow cone long throw pattern for example. And the list goes on.. LOL... One thing I will say, is that I think while the concepts are a lot to get your head around in HP aero, I think it's easy to use once it's built properly if you have the proper understanding of the concepts- I think even if you had no growing experience, you could make it work. Sometimes I think not having all the misinformation that most people have to unlearn, might even be a bonus.

Here's a great writeup on different pipe thread types... As you'll see, BSP is only interchangeable with NPT in 1/2" and 3/4". I dont't believe I said BSP was on the Accumulator, its an american company, and bsp= BRITISH STANDARD PIPE. Why not use a T instead- it will do the same thing albeit at a different angle.

Sorry for all the multiple posts in a row... My pc died (lost the raid-0 array) and I'm temporarily on an old laptop. Unfortunately I can't easily upload my weekend buildng pics yet, but let's just say I am 85% done! In the next few days I'll be setting my PRV, pressure switch, and timer- and do a full chamber mist test- YESSSSS! I am very happy with how it came together so far, it looks really nice- and if it works as good as it looks I will be happy as hell!
