True HP Aero For 2011

[Atomizer]

hmm,.. are you telling me for sure i'm going to have 3-5X as much mist come out every nozzle as i plan? Even with JG line, a solenoid, and acc?. That makes it seem impossible to hit within even 300% of <1mL per 100L in my setup then. What 'delay created by the relay in the timer and the solenoid opening'?.. I've read folks can reliable get .3 sec solenoid open/close times, r0m even said his works at .1, but figured i wouldn't bank on that. I can drop it to 12 nozzles, 2per 70L, but figured i could mist little enough with 3per.

I`m just saying it wont match the theoretical values. Solenoids and relays are usually around 20-50 milliseconds open/close. The 20ft of tubing will contain x ml`s of nutes at 100psi during the misting pulse. When the solenoid closes that pressure wants to find a way out and the only way it can go is through the nozzles.. effectively extending the misting pulse.
The actual misting pulse = timer setting + relay/solenoid electrical delays + run-on due to residual pressure in the tubing. You can`t escape run-on completely even with the solenoid at the nozzle because the solenoid and any short tube to the nozzle doesn`t have a zero volume

Nope. I'm not scared of a lil brass.

i got the stainless 4" in my cart on amazon atm, just wondering,.. why did you go with the brass one? any reason?

Ok i hear ya,.. nothings exactly as it seems,.. but put that magnifying glass away will ya, lol.. Should still help a whole lot over no acc though, and be worth the coin. I actually have a good feeling this works out really well in my setup. I feel like i'm just a better line pinch away from some big pom pom's. Must,.. mist,.. less, and more often!

He might have been refering to the SS one but it has brass internals. The one I linked to has all SS that touches the wetted parts.

 

[DIYer]

ahh,,.. thank you for clearing that up

@ DIYer
Having the accumulator/solenoid will be leaps and bounds over having just a pump. I`m not happy unless i test everything to the nth degree, as an avid tinkerer i like to know what a .1 second shift in pulse time does to the flowrate. The other side of the coin is.. if you dont know what your system is doing, how can you check if something has changed.

man,.. you are a dick head. What kind of post is that? No pictures?!? That is like screaming 'LOOK TITTIES!!'.. then there not being titties ....

I would never disappoint like that





EDIT:
Hey TB, i just bought an acc!! At Lowes! It's part of my new RO system, hehe. But let the playing with an acc like thing, its really just a storage tank i guess, but it looks like one, finally begin! baby steps..

Now that is sexy....buds and boobs. Can't get much better than that.

? for Atomizer: Got a newish grow goin. 5 plants in a 33G tote. Misting from one tube @ 2 seconds. Was using dual head, but having wilt due to poor coverage. replaced dual with a quad head still at 2 seconds (twice the volume). Was wondering whether I am better off using either a single or dual but doubling the wet cycle to 4 seconds. I am thinking I would get a better overall mist than a 2 second burst. Thoughts?

I use a plastic solenoid off eBay it's 15$ it's rated for 100 psi and I've been running it at that for 3 months with no issues.

I was cleanin out a growler... (measurment of beer), when it occurred to me that suds could make a pretty sweet root enviroment. Not bubbleponics, but in some way making a flow of suds that carried nutrients and oxygen. I think a chamber full of suds/bubbles could provide solid coverage to every root equally. Hi-tech NFT, but something worth experimenting, I think.

interesting! containing the suds might be a concern?

Its possible....its a fermentation process....compost teas do similar things....just need lots of air stones and a sealed air tight root chamber...my 2 cents

Full coverage should always come first. Limiting the number of nozzles and increasing the pulse will drench the closest roots. If you shorten the pulse you can increase the number of nozzles for better coverage and still maintain the same overall flow. Its easier said than done though

Mike,
Making large quantities of fine foam-like bubbles is easy enough if you use a surfactant. i think they`d still be wetter on the roots than 50um mist plus the bubbles wont penetrate a dense root mass.
I made a foam machine years ago, all you need is a duct fan, a full cone nozzle and a pump. Center the nozzle in a piece of duct and fit the fan behind it. Fit a disc of filter foam (1/2" thick) to the other end of the duct at the right distance so the full cone nozzle wets it completely. Fire up the pump/fan and you`ll fill the room with foam in minutes
Most soaps,shampoo`s use sodium laureth sulphate as the surfactant, sodium lauryl sulfoacetate is a safer alternative

Cavadge is/was a great engineer, everything was perfect apart from the 5 gal buckets he used. You need to be a member of the forum to see G-love`s threads, then do a search for "Atomix" in the grow diaries section.

 

[dickkhead]

atomizer you have any experience with tropf blumats Id like a self feed watering system for my soil containers in my other tent and thought these would be perfect. any suggestions?

 

[Atomizer]

Hi DH
I`ve no experience of them, mate but the kits seem reasonably priced for what they are. I bought a roll of capilliary matting (50ft x 4ft wide) about 5 years ago and i`ve used about a foot of it so far

 

[dickkhead]

thanks atom i dont think the capilary mats will work or maybe they will?... i run straight promix in varios pots mostly 5 gallon buckets how would you automatic water these?

 

[Mechanibus]

I'd make an SIP, or sub irrigated planter. You can find many examples of these, under various names like "earth bucket" on the web. Basically, It's one 5 gal bucket inside another, but the inner one has a 3" hole in the bottom, in which you place a solo cup or similar, with some holes poked in it. This forms the wick, which will allow water to be drawn up into the medium.

You also need to make some sort of fill tube to get the water into the bottom chamber. You don't top water them, the idea is to let it soak up what water it needs from the reservoir. if you were to connect all the reservoirs of all your SIPs with tubing, you could have one "control bucket" with a float valve, and never worry about watering at all.

I have 9 SIPs going right now, and I'm very pleased with the results. They might not be "aero" but you can't get much simpler. I like these better than hempy buckets.

Worth a look if zero-effort watering is your goal. I use my SIPs to flower out old mums.

Let me know if you want to see pics of mine, but I don't want to clutter TB's thread with all that.
