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![]()

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!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![]()
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...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.
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 pathIbc 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...![]()
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?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.
Nice one Treeth, you must feel like xmas has come earlyhey 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.
we want nozzel picshey TF and ATO!

those are going to be fun-Really wanted to hear that!
