Did you notice the typo for the miraculously low flowrate
0.016GPH @ 72psi (60.5ml per hour)

Yeah, they were a little higher haha.. If someone wanted to do the math, we recorded .32 gallons per hour (3 seconds on 4 minutes off) from 45 nozzles.Did you notice the typo for the miraculously low flowrate

All that math makes my head hurt haha..It works out to 0.58GPH (2.2LPH) per nozzle, which suggests the average pressure in the manifold during the misting is a little less than 43psi.
Pressure ramp: 0psi-120psi-0psi over 3 seconds gives an average of 40psi, compare that to the closest published nozzle spec: 0.6GPH @ 43psi and its a pretty perfect match for 0.58GPH @ 40psi
Running the 3sec/4min cycle for 24 hours would put 7.75gal (30L) through the chamber.
Damn, that's pretty!Or just use a good industrial spec'd pump to begin with, one that has a great track record in industrial applications. I've worked with a lot of pumps for many different applications, this isn't my first rodeo. We are not using off the shelf pumps, we have our own spec.
Our prototype used 1/2 PVC without any issues. The only real drawback is the additional volume. Once the solenoid closes you have the additional volume of the 1/2 PVC that will be released from the nozzle until it looses pressure. You'd simply use more water is all.
Here's what we came up with after quite a bit of R&D. We switched to 3/8 stainless tube with 1/8 npt bungs. It obviously costs a little more, but you'll never have any problems with it. The rack mount allows you to use differnt manifold setups.
Much ThanksDamn, that's pretty!
Thanks, we are setting the system back up right now for a LED vs T5 run. My personal view is not to strive for perfect puffy roots, but to find a happy medium between good multi-cell root hair development and maintaining a wet enough enviornment so as to reduce risk of crop loss. We are looking at this from a commercial point of view so there has to be a measure of saftey. We have some videos on Youtube/indoorharvest showing our roots..Very nice!
The craftsmanship and design look excellent
Well done
Cheers Jimmy.
hey my friend had a few thoughts for youThanks, we are setting the system back up right now for a LED vs T5 run.

I think the problem there would be the added cost to the system and the increased maintainence required to keep that many RO systems online. There risk of a properly designed RO system having a failure is minimal. For example, we are not using a single component common to what hobbyists use now. Those RO systems sold by Hydroponic shops are basically junk compared to our RO systems we source from an OEM supplier.hey my friend had a few thoughts for you
have you ever thought about adding a 50gpd RO unit to each tray. he figured in the spirit of risk prevention any component failure would be isolated to single trays rather than to the entire system, such as if your 1200gpd unit suffered catastrophic failure
he was also wondering when you plan to grow more challenging species. seeing as lettuce and basil have tiny root systems and dont require much light, fill that fucker up with roots dude.
I'm sure you'll snicker.. but yes, we have designed a skid fixture just like our nutrient system that incorporates two large tandem pumps with a large accumulator. Really just depends on the application and the customers budget.You`d need a football field sized place to warrant something that size
Your 1200gpd RO should be enough to run at least 150 chambers (30L/day) drain to waste. Centralizing the RO system for low maintenance makes good sense, as would centralizing the irrigation system. You`d cut the maintenance of 300 pumps, 300 accumulators, 300 solenoids and 150 timers down to 1 big pump + a backup, 1 large accumulator + a backup, a bank of solenoids and a few timers. It would free up more time for checking the odd 6,750 nozzles
