I like the pushfits, it would be worth checking with the makers if it can handle high pressure (100psi) and whether it would affect the readings... I can`t think why it would but you never know.
I haven`t noticed any detrimental effects with nutes under pressure but TF had some issues with caked up pipework. I`m not sure if it was tank related or due to nutes sitting though.

I was being facetious about the value of the american dollar.

Good find! Ato, I could have saved on that website, if you can also find the adapters...

"Thank you for your order for (4) Delavan SN nozzles at $42.41 each and (4) Delavan adaptors at $39.95 each"

... The part number for them is 17147-1

Yeah I like it too and the price isnt that bad either. I was wondering what orfice size yall are using. I am looking at different ones and trying to decide. The ones I have seen are either .016 or .025, which size would yall choose for the 80 to 100 psi range?

Hi Treeth
Sorry it came too late to save you some $$$, at least you`ll know where to find them if you need some more. I haven`t come across any adapters but if i do i`ll let you know.

Hi Travish
mine are 0.62mm which are equivalent to 0.025", it can get confusing converting from one thing to another. For the biocontrol nozzles I had to use an online convertor to figure how many ml`s was in a us fl oz :)
I found the nozzle flowrate varies with pressure, the spec on mine is 4.9LPH alledgedly at 3bar and 5.5LPH at 4bar, i tested the flowrate at 6.5bar and they do 6.75LPH. The biocontrols do 0.08 us.fl.oz/sec which equates to 8.51LPH, if thats geared to 80psi it`ll probably put out slightly more at 100.

As bad as I hate to order from bc i think i am going to purchase their .016" spray jets... The specs show .04 oz a sec so that would be around the 1 gallon per hour if my math is right... I found some mister/foggers on this web site http://www.ezmister.com/index.php?option=com_content&task=view&id=10&Itemid=25 and as you can see their specs show .55 gallons at 100 psi. I contacted them and they said they had some that had a smaller orfice size that wasnt on the site for $3.25 ea. But that is just for the fogger alone not the fittings. So I am debating on really which of these I want to go with:confused:

Im thinking about getting one of these tds meters http://www.waterfiltersonline.com/de...meter-inline-2 and running a feed line from the main line between my nutrient resevoir and pump and looping the feed line back to the main line... Make sense? These meters are half the price of any others that I have found. Do yall see any problems with that besides the psi being a issue with the readings? I guess I would still need to get a probe atleast to measure my nutes before they get pumped into the system. But it would keep a constant check on them. Any opinions?

i hope your not going to put those 4 nozzels in just one chamber. unless its a big chamber.

ive spent 2 days trying to find a pump just like the one i have and it has been frustrating to say the least. alls i want to do is buy a pump. how hard can that be. well the pump i have now isnt made supposedly anymore and no one seems to be able to tell me the specs on the replacement model and whether it has an external bypass. i even talked to shurflo rep (if you can call them that. i knew more than this guy about pumps)and they are uncertain. what a joke sell a product and dont know anything about it. i found a website that has some but no number to call and they dont answer email so im not buying. the pump i have is working great and thats why i wanted to get another one for when this one dies. hopefully someone willc ome thru. you know it takes longer to find this stuff than it takes to build.

the bio nozzels have been working fine. ive only had one go bad so far. didnt try to fix it just replaced it. running such low concentrations of nutes with HP really helps with the nozzels staying clear i suspect.

i wonder if those fuel oil nozzels have the same mist data. they sure are cheap enough.

now that i think back when i had the caking issues. i was running LP aero with very high ec levels. i dont think you would have that problem with a bigger tank at the ec levels that HP runs at.

I know stuff can precipitate out of solution at higher ph, theres no data i can find on precipitation due to pressure. I would guess that nutes under pressure in an airtight tank are in a preserved state much like a bottle of coke or can of beans so its likely any change will be slower than a normal res exposed to the air..could be completely wrong though :)

Most nozzles give you the flowrate and pressure specs but little else to make comparisons. Things like a narrow pattern or short throw could mean using more nozzles to get the same coverage. Small orifice nozzles tend to clog easier although low EC may offset it.
I don`t think a one size fits all nozzle exists as the shape of the chamber probably dictates the best nozzle for the job. A wide angle, short throw nozzle may be ideal in a wide shallow chamber but not so good in a long deep chamber.
Might be best to buy one of each to test and then decide :)

It seems the nozzles can be used for fuel or water, the 30609-11 nozzle spec is the last one on the pdf

What I had intended to orde was two 10's and two 6's. I figure I can order four brass for less than the two 10's I was going to order in stainless steel. Once I see how they perform in a 9 square foot cell, I will decide which to order in stailess. The brass ones I will use for cloning and stand bys as I want to use stainless steel with the pods using nutrients.

I have even left two phone messages for Stephen but no return calls.

Where I have had carbonate precipitation is any where where any heat builds up. Meaning at pump entrances and discharges. Any place where there are restrictions such as a 1/2 valve with a 1/4 orifice. Sharp bends and 90 degree fittings. It doesn't take much heat to cause soluble calcium to precipitate.

Thanks Atomizer!!!` As much as I buy off of eBay and I never thought to look there for nozzles. I emailed an inquiry to a seller on eBay with the #28 nozzles. I am definitely interested in what its spray volume is as the listing online at Delavan only goes to a #11 and it maxs out at about 3.8 to 6.3 liters per hour. I would like to test a couple in a chamber that had a flow rating about 9.5 liters (2.5 gallons) per hour. For a 18 to 22.5 cubic feet chamber that doesn't sound bad.

Glad to help, its a pity he doesn`t do the 6`s and 10`s. Just need to find some bambi silent compressors for $24 now ;)

How are yall setting the air compressor systems up. I get the concept where the liquid and air mix in the nozzles just was wondering how the system was actually put together?

I think 9.5LPH may be too much but you can always reduce it. Looking at the numbers 9.5LPH works out to 228L/day in a 22.5ft3 chamber or 10L/ft3/day.
I think TF may be running something around 1L/ft3/day. Working on the assumption he has four 4.48ft3 chambers and 16x 8.51LPH nozzles running on a 2 sec/6 mins cycle. The total nutes delivered would be 18L/day (4.77gal) into 18ft3 of chambers.

I must be having a senior moment, its unlikely you`ll be running a nozzle constantly ;)
This is a bit more like it.. 2x 9.5L/hr nozzles in a 22.5ft3 chamber with timing cycles of:
1 sec/60 sec = 7.475L/day or 0.33L/ft3/day
1 sec/120 sec = 3.768L/day or 0.167L/ft3/day
1sec /180 sec = 2.519L/day or 0.111L/ft3/day

Got a return email. The number 28 nozzles are rated at 2.2 gallons per hour. Looks like the ones I will try firts. And for half of Stephans quoted price. Time to spend some more money, so off to eBay.

I ended up ordering two #7 nozzles and four #28 nozzles and 6 adapters. I am not sure about the #7's. They are maybe a bit small but I will try them on a cloning and early veg/rooting chamber so they will be in a chamber of only about 8 cubic foot. Their max flow is about 4.8 liters/hour each however I doubt I would run them at that flow rate as I imagine the droplet size would be quite large that flow is at a high fluid head and at a low air pressure. It was strange actually paying more for the adapters then the nozzles. I figure now between adjustments that can be made with varying the nutrient head heights and air pressure I can probably dial in the droplet sizes I want. If I do not like the volume at that droplet size as all that type of nozzles use the same adapters and everthing before that (piping, valves , compressor remains the same) I can also try different nozzles for not a large sum and still not have to over water each spray period.

The average prices on eBay were just $19 to $24 each. Stephan sent me an email again saying he does not accept payments online or through eBay and his quotes for the very same brass nozzles and adapters he just sold a few days ago are now 2 dollars more each. I round can filed all records of emails with him. I do not need to put up with his poor business ethics/practices.

I think initially I will try to swing nearer the under watered stage rather than the over watered stage. I can only wait and see how it goes.

Hi Fatman
I think it`ll be a case of testing the various nozzles at different flows and air pressures to see what kind of pattern and throw they generate. Most of them seem to get narrower as the pressure increases.
Ideally we need someone that owns an atomix to let us know what the flowrate is at min/max air pressure along with the syphon height :)

Travish
As far as it goes its along similar lines to using a pump. The compressor fills the tank with air and its released to the nozzle with a solenoid valve. The nute delivery can be either via a syphon where the venturi effect of the air draws nutes into the nozzle or alternatively by using the gravity feed method with the nute tank located above the nozzle. The drawback is that you`d need another solenoid to kill the nute flow. The syphon method delivers less nutes but is easier to impliment.
