800psi rules out JG pipe and fittings, you`d need to use semi rigid nylon tube. You`ve got at least 4 methods of producing mist, i`m sure you`ll find one you like sooner or later :)

So it seems like the best route for a novice seems to be the biocontrols and an Aquatec.
I love the thought of those SS, waiting to hear back on what they tell him on pricing! Even if the cost is sky high, if you need less, and they last longer then that's a win in my book.
To be honest I won't be using this to grow MJ (have a separate grow for that), but used to test a possible business opportunity growing vegetables. Saying that, I don't mind dishing out the extra for the SS unless they are something crazy like 500+ a pop.

Have these ever been mentioned? I imagine they have; aqua aircon sounds so familiar. No micron mist mentioned, but they run on 100psi, which seems less than others that appears similar (I think I've seen 500psi?)

I hate to think that two years ago I could have got all of these fittings and more for free from the company I worked for. If only I knew :weed:

Trichy, you mentioned recently about creating your own root chamber? Let me know what you decide. I remember reading it somewhere about using pool liner; I need to better label my bookmarks.
I was initially going to use an old chest freezer, but I would love to make my own; 4ft H x 5ft L x 5ft W as an example.

Cheers,

I`ve used fogco and amfog nozzles which are very similar to those in the ebay link. They`re great with RO but very prone to clog when you run nutes through them. You`ll find you`ll get partial blockages which turn the mist into a jet and its all but impossible to unclog them. Things that dont work.. overnight soak in acid, compressed air and water at 50-bar pressure fired through the front to backflush them ;)

Very good point, that has actually been a concern of mine with all nozzles. I love that you so many of you have already tried these angles. A toke in all your honours, for doing the legwork I'm to high to do :-P

Atomizer pointed out to me in the past the chest freezer idea, especially if retrofitted with a warmer range thermostat controller to keep the chamber the correct temp zone for roots. You can pretty much make a chamber out of anything, wooden box with a pondliner, etc... I also don't believe you need to make the chamber so tall, 2 feet is probably enough. The roots hit the bottom no matter what, but that's not really a problem as long as you have proper drainage...

My newest chamber design will be made with sheets of foamboard 3-4 inches thick encased with fiberglass/resin like a surfboard. I plan to add some lines within the walls for recirculating chilled water that should offset any heat that gets through the walls, although with as much insulation as I plan to use, perhaps it will be unnecessary since I will also be chilling the air/nutes just before they get to the nozzles.

Thats a big chamber, 8x8? is it going to be MP, HP, RA or AA aero? ;)

Nice- an indoor kiddie pool that makes sure they still get a tan ;) Kidding of course, you care to explain more what the plans are? Looks interesting for sure.

The root chambers will be 4X8X1 or 32 cubic foot. The base design will use two Shurflo 100 PSI pumps per rack pushing 45 Teffen nozzles. I am going to experiment with a number of other nozzle types and pressures so the setup may change somewhat.

The lid design is modular ie: you can switch out hole size, placement and number, or go to a 4X8 grow mat for micro greens. The inner manifold will also be modular and can be swapped. So if you don't like the Teffen nozzles, no sweat.. just swap the nozzles, or change the manifold.

If you are growing micro greens, you can do a three tray stack. I'm going to be growing Basil for our demonstration.

My goal is a MSRP under $6K (commercial system, heavy duty built), but the system is designed to be used with a separate nutrient system as there are no reservoirs, the system will be drain to waste.

For an idea of ROI, this system should be able to grow 32-40 lbs of micro basil per month.. micro basil is fetching about $32 per lbs.

Looks very nice, what made you decide to go HP hydraulic vs. the other alternatives?

I use 24 nozzles in a 56 cu ft outdoor aero chamber and run about 20L a day to waste. It`ll be interesting to see how it compares to a pumped system.

Be open to the idea you may be thinking of using too many nozzles here. It will definitely affect your bottom line in a DTW scenario of too much runoff. If you can get adequate coverage with less misters it is much more ideal and will probably be less prone to oversoaking your roots too. Are you going to try using an accumulator or not? Reasons?

I see you running around trying a bunch of different ways of doing things here, which is exciting and commendable. However, it doesn't hurt to at least try once a method already proven to give good DTW results, at least as a benchmark and learning experience to build off of IMHO.

From a commercial standpoint it made the most sense. That's not to say I haven't ruled out other options or that I'm not going to try them. I have to start somewhere and this route made the most sense to start with.

I've considered that and the way I am designing the manifold inside the root chamber I can do quick changes to the number of nozzles, runners etc.. It will make more sense the further along I get. When finished, this one system will be very modular, meaning it can be easily tailored to every growers needs. It will also make R&D easier.

I'm having a lexan lid I'm going to use so I can see how the nozzles spray and what patterns they provide before I ever even start growing. I'll document it on video and share it.

Yes, I do have a few accumulators heh..

I`d send the accumulators back for a refund if you can as they`re way too small to be useful. By my reckoning, you may have upto 50ft of manifold in the chamber which will contribute to a significant amount of run on. The shortest mist timing will be dictated by how long the pump takes to pressurise the manifold and get all 45 nozzles running, perhaps 3-5 seconds at least. When the pump stops, the manifold will depressurise through the nozzles adding to the overall misting time and nutes going down the drain. You could be looking at anything upto 100L per day.
