68 bar pressure, it could double up as a pressure washer :)
Its brass which isnt good, not forgetting the noise it might make.. i`d get moaned at bigtime if i fired my pressure washer up at 3am :)

:lol:Ok I am having a really hard time with this... So, I have a sprinkler pump that will maintain 70 psi and a 20 gallon acc tank. My room is 5x5 so I think I am going to build a 4x4 grow chamber that is about 24 to 30 inches tall. How many misters would you run and what kind of regulater? I orderd the regulater you linked me to but it wont be here til january so I am just going to buy one at a local hardware store, but your input would be greatly appreciated!

I just purchased my pump and tank and can return them if need be. I dont know if I went overkill but i think i was not using a big enough pump since tree farmers pump was capable of 150 psi. I want to us the 1 gph misters/foggers or I liked the ones that atomizer uses with the egg shape. Since i am going to be growing in a big chamber i thought those might be better but i wanted to stay in that 50 or better micron level. Maybe I will have this figured out soon:wall: Its a whole new world compared to any other system but I like it bc I think ppl are too scared to try and tackle it. I wouldnt be able to if it wasnt for all yalls help. If I could share the rewards I reap off this system I would do so in a hear beat!

Hi Travish
All setups are slightly different (layout, nozzle type and orientation, pressure used etc) so its hard to come up with a one size fits all.
For a 4x4 chamber that deep i`d be tempted to use 9 nozzles on a 1ft x 1ft grid, suspended 6" off the chamber floor, firing upwards. If you divide the chamber into 1ft x 1ft grid each nozzle will cover 4 root sites with some overlap.
I`m going by the nozzles i use as i know what pattern they generate and how far they throw, other nozzles would be different.
When figuring what size the pump/tank needs to be, i gear everything to handle a 1 sec on/60 second off cycle just as a design reference.
Here are the theoretical calculations for a 9 nozzle system. It doesnt take account for any mist run on or changes in nozzle output versus pressure. I`ll base it on my nozzles and pressures (64-92psi) and your 20gal accumulator.

9 nozzles in a perfect world will deliver a total of 16.875ml in one second to the root chamber in a 1x1 grid.
With a 64psi cut-in and 92psi cut-out, the 20 gal accumulator has a drawdown volume of approx 19.8L (~5.25 US Gal)

Using the 1 sec/ 60 sec cycle, it`ll take approx 20 hours for the tank to drop from 92psi to 64 psi at which point the pump kicks in to put 19.8L back in the accumulator at 92psi. With TF`s cycle time of 2 sec/6 mins the tank drawdown time increases to around 59 hours. HP aero doesn`t need much of a pump ;)

With the 1sec/60 sec cycle you deliver 1LPH to the chamber or 6.31 us gal/day.. that`s maybe 6x the amount TF is running into each of his chambers :)

That sounds good! I am off work tomorrow and will try to get my grow chamber built. I have some white widow seeds on the way. I plan on growing some mothers and taking clones but I'll start a journal and show yall my progress. Thanks again for all the help!

I had an idea and was just curious if any of yall have thought of it or tried it. Im playing around with hho boosters and installing them on mine and my friends cars. How do you think the roots would respond to hho being pumped into the chamber? It makes since with the thought that plants need water and water is h20 so would hydrogen gas be harmful or do you think it would actually help? Just a thought and wanted yalls opinon.:bigjoint:

A 1000L black ibc tank without the cage would make a nice 4x4 root chamber or maybe two, cut it down to the height you need.

Ibc tank?? not sure what that is. I'll google it and see. I was going to do it the hard way. Some OSB and pond liner...:?

Just saw a pic of one. Yeah that would be perfect. I dont know if i can find one where i live though, unless I drive 100 miles... I live kinda off the beatin path:peace:

hey TF and ATO!

guess who got their delevan parts today!?

Thats right. This guy.

I'll post some pics when I get everything running in a week or two, now that I have each critical part,

run to waste nutes included.

When filling an accumulator tank with a pump does the pump have to be able to reach 100 psi to fill the tank at this pressure or will any pump reach 100 psi eventually just take longer if it insnt very big? I have a 20 gallon tank and returned my pump bc it said it would only maintain 70 psi so i didnt think it would be able to pressurize my tank to 100 psi... I am hung up on what kind of pump to use... I would prefer to use a large aquarium pump so it wouldnt be so loud but didnt know if this would get the pressure that i needed. I plan on using 9 to 12 nozzles at 1gph.
Thanks for any advice!:leaf:

Iwaki puts out about the highets pressure pumps typically used with aquariums. Their fracion hp magnetic pump lines maximum pressure pumps are the MD-70RZT at 42.7 psi and a flow of 11.4 gallon per minute, or the smaller MD-30RZT at 24.2 psi and a flow rate of 4.5 ga;llons per minute. you would use thm without accumallator tanks and would run them cosnstant with solenoids. I use them on aero tubes. They put out a finer mist than the low pressure pumps and use the same misters but they put out a larger droplet size and less flow than the HP pumps provides through the same misters. I just refer to itas a medium pressure inre termittant aero sytem. I use soleniods on a timer so that for 5 seconds on and 30 seconds off. The droplets size is large enough that the fog/mist is gone in just a few seconds. It would likely work better in a chamber but I doubt that the 20 to 45 psi could ever provide the mist put out by the high pressure pumps or the air atomizers. Iwaki pumps are not cheap. I have been lucky enough to buy all of mine on eBay but retail they sell for $300 for the MD-30RZT and about $450 for the MD-70RZT. Basically it is just system in between a low pressure and a high pressure system both in performance and cost.

What do yall think of the ultrasonic foggers. I found one that was around 160 dollars and produced 3000ml an hour... Thats about 18 gallons a day... I was thinking of using the method without the tank and try these foggers with the misters. Whats your take on that idea?

How did you finally get Stephen to take your order? He sent me a email with a quote and some PDFs with some copies of order forms info, but did not say where to send them. He does not return phone calls or emails. He wrote I can order on line or from him but the urls are just the Delavan catalog sites and they seem to provide no way of ordering on line. Did you order from Stephen or an online site from Delavan rather than Stephen at Goodrich. What size did you end up ordering.

The first time I contacted Steven, thats what I wanted... A link to a distributor. What Steven immediately did was to refer me to the most geographically proximal machine shop which is allowed to hold the Delavan design specifications. Only after that did I try to ask Stephen if he possessed inventory, which he flat out denied having. I'd be happy to link privately to the sales representative who took my order. I paid 339.98 pesos for my 4 examples, shipped, (nozzles and adapters).

I ended up getting metering size 11, which I think was nearly the 'largest', I cant remember what was 'appealing' about the flow/gravity head chart...

And I really didn't know to ask for any opinions on it, why fatman,

What were your thoughts?

-Oh yeah! And I was pissed that the date on none of my pieces was 2009! I thought I paid for them to be machined just for me in a production run of four!

I love production.
