If they drink a couple of gallons a day and Atomizer is only giving under and ounce per gallon of chamber space per day I'm not seeing how this amount of solution is meeting the plants needs. Lets say you grow one plant in a 55 gallon barrel. That's under 55 ounces of solution being misted with...

Doing a little fuzzy math you are putting .0013 ounces of water per 231 cubic inches of chamber space per misting cycle. If you mist every 2 minutes that's about .94 ounces per 231 cubic inches per day. How large is your chamber? How much solution is not absorbed by the plants at various...

Try it. You didn't really answer the question. Are you willing to just out and out share what you are using or are you protecting your configuration for some reason? Can you answer what nozzles you use and what you are using for your pump or pressure?

I don't know what you are telling me. Yes, larger orifice larger droplet, BUT the orifice size also produces a different droplet size based on PSI. I simply said I use a variety of nozzles. What nozzles do you use? So how is your system configured? With the type of plants you guys grow you...

Not at all. If you read my other posts it's actually quite the opposite. Both low pressure with accumulator and high pressure have merits.

Bob, are you having any extreme issue with clogging? I'm curious about the nutrient issues clogging the system. I really do wonder if given the same nutrients and same exact lines etc if 100psi and 1000psi would behave any different. I wonder if anything other than calcium is clogging your...

Its hard to tell what we are looking at in that pic. Do you have clogging issue when using soluble non organic nutrients? Maybe something like Dutch Master? Is it due to the salts or the fact that you might be reusing nutrients? Do you filter and if so how fine do you filter? If you are using...

Lets change the topic a bit. I'm curious to know if any of you have experimented with using a Surfactant in your nutrient solution. Do your Nutrients contain a Surfactant and you don't know you are using one already? Have you mixed your own Nutrients and purposefully added a Surfactant? For...

That's fair. If you haven't tried then you really don't know. I'll take your comments as arm chair opinions. I don't have the issues you think I have. Sub second is possible. Honestly, in a commercial misting system you are running for hours and hours and hours without changing the misting...

Not really. You are stating your opinion as fact without actually explaining yourself. I've looked through your posts and it's pretty common so I wont take it personally. Commercial 1000psi misting systems run in public places all day long with solenoids. Not sure why you believe this is an...

If you want to stay around average line pressure I'd imagine an Aquatec 8800 plus stainless Shurflo accumulator would be close to ideal. That combo might run you $325 or so.

I think you misunderstood. I understand too much mist. I don't understand saying: Why do you think a 1000psi system would innately lack or not be able to achieve perhaps the same control or better than a lower pressure system or a system that doesn't even use pressure? Perhaps you haven't...

Can you link to where you are outlining what you think people should be doing? Overmist? I really don't understand that. What do you mean? Note: it's been mentioned before up thread, but I actually don't grow what you guys grow. You mostly post negative things. Are you trying to help people...

Atomizer, lots of comments about what people are doing wrong. Do you have a post or thread somewhere where you discuss what you are doing and what you think works best?

PetFlora, The guy that wrote that article is the sales guy for Aerolife. It's marketing material. $160 per Nozzle.... http://www.aerolife.com/index.html

So, is it a Dremel or similar motor in that PVC pipe? I'd imagine you could make that thing a lot smaller and a lot safer if you simply used a DC motor. You don't actually need anything near the kind of torque a hand held rotary tool outputs. You just need high RPM's from what I can tell...

Sure. I'll see what I can put together. Arduino is easy if you can even just use excel formulas, but that DIN unit looks pretty easy as well and it has a web server. Check out the scripting. It's basic, but there is threading so switching isn't executed in a serial fashion. It's concurrent ...

I have my own design. That said you can take a look at the i2c relay board from GHI (http://www.ghielectronics.com/catalog/product/169). GHI sells arduino like products, but for the .net micro framework. Their relay board is i2c so its really compatible with arduino or anything using i2c...

You drop the line pressure by first shutting off the line from the pump with a solenoid and using another to drop the pressure by opening. Think of it as using non drip for the crack instead of the drip. I don't use timers. I have a control system. A person could do the same as me with...

Yes. Agreed. The reason for solenoids and non drip mist heads that crack at 250psi.
