True HP Aero For 2011

[r0m30]

listen to this man, he knows his shat

Just a beginner, and only a few steps ahead of you in the process.

i found it benfecial, as r0m has previously stated, to keep a common voltage between equipment

Yes I did say that but I think any complexity added by using a wall wart in a 120VAC system to drive a low voltage solenoid is more than offset by the added safety and the reduced likelihood that you trip a breaker (if you're lucky) when some water escapes those pressurized tubes. You WILL get wet building a HPA system

Thanks for the reply, will do on the voltage issue.

The issue was that freshwatersystems has molex connectors on the ends of the wires, so, I was ideally looking to match molex/molex for convenience, are you suggesting stripping the wires and connecting cords, or do you know of a molex to ac cord, I will look my self after I finish this post, honestly if running cords is just as safe and cost effective, then I see no reason not to go that route. My only concern is I haven't worked out my layout, so I do not know how many solenoids, molex/cord(s), I would need, and so the cost benefit will be a mystery for a little while. Thanks for all the help though, I think like 99% of this is layout.

BTW, I forgot, who it is but whoever had the idea of using the basin tubs, genius sir, other than cost, perfect form and function, especially with those drains on the bottom.

Anyone know how you'd incorporate the sprayers from cloud tops inline with JG? Been looking for a misting tee that exists in JG native, no luck so far, NPT would be the next option, still pulling a blank on that, finding barbed for vinyl, and PVC no problem, as that's what cloud tops uses.

If I could figure out a way to incorporate them, I'd like to, otherwise it's probably going to be one of those swiveling brands from Reptile Basics or MistKing, a or b.

Another thing I just thought of Mike, you say you got those little sprayers at HD, I'm not an anal guy about what gets the job done, my only question is, since you've made sure they have the right droplet range, how did you install them in your JG lines w/o leaking? I think you covered this before, so I apologize, I'll have to search your posts, if you feel like answering in the meantime, thanks.

Ok I was going to mine for this micron size chart someone posted, I don't know if it was here but if you're the one you know what I mean, please post it for the others.

not the OG but here is a good reference

 

[foresakenlion]

I'm trying to look up the size of those misters you pointed at Mike and all I can find is a definition of fog/mist/cloud is very vague and seems to indicate a range of 1-100 um. If anyone has more concrete details on this from a scientific definition, please do interject.

http://www.atoptics.co.uk/droplets/clouds.htm

so it follows that a fogging mister would be 1-100 um, phew, ok I'm just being anal about the droplets, and there's no info available on the site other than the name.

The issue was that freshwatersystems has molex connectors on the ends of the wires, so, I was ideally looking to match molex/molex for convenience.

I know the 24VAC Aquatecs have a molex connector, I didn't really look at any 120VAC pumps. If the 120VAC pump you're looking at has a molex connector you could splice a cord onto it or even replace the wiring completely. Why don't they sell a compatible cord? Is it a specialty item designed to go into a larger piece of equipment?

I don't think anyone has found a push-fit to 1/8 NPT tee. I used the push fit to 1/8NPT female combined with a push fit tee. It's part number pp450821w, here is the JG page, and these puppies aren't cheap

@ BD Thank you for the chart not the one I was talking about but any chart is useful for the people that read this in the future,

@ R0m they're a special model for air pencils and steamer / vaccums I take it, they have a higher psi by default than the ones offered at the mist stores, and they have a default pressure switch on one of those models I listed in the electrical thread, just gangjadigger electric and high pressure aero, the psi on their pressure switch is set to 80 psi by the highest, far higher than the RO ones, also they're a triplex valve, this is supposed to eliminate the kick in the lines when using the air pencil. I guess that makes sense because that jolt in an aero is just an annoyance, on an air pencil when you're doing fine art that's murder.

and excuse me for asking how they secured those cloudtops, I still don't know how you'd do it on a JG line, but I believe he had used PVC and some kind of tap that creates threads, then he merely threaded tightly, no leaks for that method. I'm only anal about going for a cheaper method because I'm trying to work out a methodology for people that really need this, so possibly I could do a write up on for instance TY, as I know they focus more on serious ailments than the other forums. That is no slur against this fine forum though, merely a personal commentary of how I view each in my humble opinion. I wouldn't want to step on toes. Oh btw if someone takes the idea and beats me too it, no hard feelings, people need this knowledge. Aero has the potential to be a Rosetta Stone for the straving masses, we may be applying it to Cannabis, which is just an herb, but our collective knowledge will benefit far more in food production than it ever will in growing Cannabis.

After thinking this through a little more, you wouldn't wire the pump straight to the 120VAC you would wire it to the differential pressure switch and unless you use an Aquatec switch and their prewired harness you're going to have to match up connectors anyway. So do whatever works best for you.

I don't see any need for the triplex valve in HPA, the kick that you have to worry about is the one from the rapid opening and closing of the solenoid.

The pressure of the standard Aquatecs is adjustable with a simple turn of a screw and you would need to either disable or set the built in switch to a point where it didn't interfere with the differential pressure switch. What is it you think makes these pumps more desirable?

and excuse me for asking how they secured those cloudtops, I still don't know how you'd do it on a JG line.

You use the part I linked to above.

First off i'd thank those that have contributed this very informative information.

I have a few questions regarding HP aero. So it seems that generally a vertical setup is advised against as the mist will have issues flowing/ or not getting all parts of the root. Here is what I had in mind.

12" dia x 42" with 4 misters, placed evenly on each side near the top, at .2 secs using biocontrol nozzles( havn't figured out the off time yet ). Will this be large enough to create a true aero environment?

Second question, since i will be using a separate chamber for each root system it seems much easier to do a DTW. I had questions regarding DO. Would it be beneficial or detrimental to have small amounts of air flowing in from the waste pipe? I'm planning a 1" drain.

What is the smallest volume required per plant for an SOG grow? Orginally i wanted to do 2 plants in a 12" x 42" pipe... this is obviously too small?

would this work to form your own plastic containers?

I have a few questions regarding HP aero. So it seems that generally a vertical setup is advised against as the mist will have issues flowing/ or not getting all parts of the root.

I was reading on another forum and someone suggested a stadium arrangement for HP aero. I can see that type of setup working with the chambers staggered and the upper chambers having a longer neck. I don't know of any working vertical aero grows though.

Here is what I had in mind.

The math puts that at about the right mist delivery, but given the electrical and mechanical delays it would probably be to much. You really need to test the components you choose and dial them in.

Second question, since i will be using a separate chamber for each root system it seems much easier to do a DTW. I had questions regarding DO. Would it be beneficial or detrimental to have small amounts of air flowing in from the waste pipe? I'm planning a 1" drain.

Additional air flow would cause the roots to dry out more quickly. DO is really an issue when the roots are in water because they can only get oxygen from the water. In aero the roots a continuously exposed to and draw the oxygen they need from the air.

What is the smallest volume required per plant for an SOG grow? Orginally i wanted to do 2 plants in a 12" x 42" pipe... this is obviously too small?

No experience but my GUESS would be that two plants in a 12" diameter chamber would be to many.

I never assumed the triplex was better, but thanks for clearing that up r0m, I merely recommend those because they're less than the 200/220 models and they are less expensive for the psi.

 

[bishs]

thanks for the reply rom..

does anyone have any opinions on the sizing of the chamber that i have provided?

 

[foresakenlion]

It may be full of roots by the end, they would most likely touch the bottom before the sides, though in Aero it could puff out faster than it grows down, just my opinion, a foot should be a good baseline.

 

[bishs]

I'm wondering, would a ebb and flow produce greater results compared to a hp aero setup with a small chamber? I was really aiming for the aero setup but i dont see the point if i cannot reap the benefits. Someone please convince me lol.

 

[foresakenlion]

Tuned F&D vs Tuned HPA = Aeroponics, less water, less nutrients, higher growth rate, less bacteria, fungi.

Downsides the need for all this redundancy we're talking about.

Thanks r0m, I'm a visual guy, pictures worth a thousand words. Went to HD, Lowes, they were out of the PVC I needed at HD, went to Lowes, got 4x 1/2" end cabs, slip, 4x 1/2" x 1/2" slip, x 1/2" NFT, 4x 1/2" NPT to 1/2" slip, 6x 5 ft 1/2" PVC, pipe cutter, priced reflectix, and the JG fittings there, for those that go to retail, they just call them quick connects or compression fittings, JG got nothing but blank stares.

 

[konagirl420]

GO TB!!! hehehe

 

[foresakenlion]

Just got done laying out the scaffolding with PVC, for those that ever have to try this again, for a Botanicare claiming to be 2x4' you need to cut two lengths to 38" for the length, for the depth you need to cut four pieces for the corners, they should be 3 3/8" inch + 1/2" slip cap + 1/2" x 1/2" x 1/2" NPTF this will give you a a framework to mount your misters, got some extra left over to make a canopy screen.

Aeroponic`s will out proform a bucket system everytime the major problem is people try to reinvent the wheel and think more is better WRONG With aero less is more ...........................nutes nozzles etc

 

[PetFlora]

E&F done right produces EXCELLENT results. I may do a side by side at some point. It is certainly more forgiving as the roots are protected from heat via the stones, however, this can be minimized by distancing the lights from the table and/or insulating the table. Of course cleaning those stones after each grow is a RPA.
