    It's about time you realized that product was dangerous. :clap:

    OP, what ya doing about the H byproduct? This thread is kinda old and haven't heard from the OP since Dec. You didn't blow yourself up did you?:fire:

    This was my initial worry when talking to the guys at O2 grow..
    Here is the exact email that I received from one of their reps..

    ''For some reason people think we have generated some excess hydrogen that could be explosive or harmful. The fact of the matter is most of the separated hydrogen is also re-absorbed back into the water because the molecule formulation doesn't change, ( H20 ) however the DO level increases because we convereted it to a soluble gas. Yes some hydrogen will escape, but technically not anymore than if it was evaporating like your environment does now with evaporation. You have lots of evaporation going on in those rooms. Plus you may be adding Co2. So with that said, hopefully your concerns have been addressed. Even though we are using an electrolysis concept / science, no one has done what we are doing in horticulture. Mainly because we have patents on how we use eletrolisis and our designs doing so.

    There are a lot of thing you can do with electrolysis. One is swimming pool chlorinators. But in that case the Anode / Cathodes are further apart. our patents are 25 to 60 thousands of an inch. Further will make chlorine if you add a lot of sodium chloride to the water (salt ). There are also ways to capture hydrogen in a more complicated design concept and thats what a lot of people find on the internet. Unfortunately no one has ever established a good method or product to do that effectively.

    There’s even bloggers ( The University of Goggle ) who tell people that you can make our technology for $10. Good luck with that. The iridium that coats our Anode / Cathodes cost $900 an oz. Thats is a precious metal used for conductivity in your cell phone , laptops and now Led’s are starting to use that material and that has up the price. It used to be dubbed 9 the cheap gold ) It’s now just under the price of gold. 20 years ago many tower computers used gold in their circuitry. There were companies formed that reclaimed that gold.

    Hoped this helped''

    My main issue was I run a closed loop RDWC system and was seriously worried about the H2 gas build up but was assured that it was negligible and would just be absorbed back in to the environment..
    The reason that I decided to make my own was not a financial issue, it was purely that the rep prevoked me saying it wasn't possible to do what they have done for cheap! I accepted his challenge..

    Also, if there is no supplimentry oxygen then in a DWC setup the plants will drown.. Not only does this type of tech double the amount of DO in the solution compared to air stones (making the nutrients more readily available to the root system) but also helps to fight against diseases..

    Here is a pic of how much DO is made in less than 45 seconds with my simple diy..

    Hope you didnt use stainless steel instead of platinum or iridium coated titanium.

    All I know that with my RDWC system (modified waterfarm) I grow huge plants with zero root problems. Simple air, (oxygen) provided to the root system is all that the plant needs, this isn't rocket science to grow a healthy plant.

    Yeah, just for the proof of concept design..
    Waiting for my IR coated expanded plates to arrive from China. .

    Yes. I have grown many successfully with the use of air stones.. Problem is with using air pumps on a closed loop system is that you need to get the air for the pumps from an outside source so with my X4 100LPM air pumps located outside my room I'm adding 400LPM into a sealed room!

    The test water is classified as hazardous waste so dont get it on your skin, dump it down the drain or consume anything that was grown in it ;)

    I'll bare that in mind... I'm sure that the only issue is the breakdown of the anode though that makes it even slightly hazardous.. Hence the need for IR coated titanium anodes.. The only other thing that it creates is chlorine if the anode and cathode are incorrectly spaced.. They use the same tech in water treatment plants.. I may be wrong on all fronts here but that is what I have read! ☺

    Your test water will contain chromate from the stainless ;) You wont have that issue with the IR coated ones but you may need to supply Cu via foliar feeding.

    I'm a little fuzzy on the science here. Are they saying the majority of split O2 and H molecules will reattach back to H20, so there's very little actual just O2 and H molecules left? Light a match over that experiment you did and see if it flares up.
    I've said it before, I've worked with supplemental hydrogen generators that were pretty much this same setup, as far as I can see, but the gases were collected and directed into an engine. I had to fix a collector vessel that blew up due to a small leak and bad wiring. The vessel was maybe 1L capacity and the owner said it rocked the vehicle when it went off. Personally, I wouldn't take the chance when air pumps work fine 99.9% of the time.

    Why not do a simple floom/venturi set up?

    This is 3 gallons off a 260 low pressure pump with a simple DIY venturi

    There's no doubt that stored hydrogen is extremely explosive, but I've decided to put my O2 generator in my control bucket which is located in a separate room that is vented, so I very much doubt there will be a buildup of H2 gas.
    It does crack quite a bit with a flame to the top of the water though!

    My system is 40X40L buckets with a rough total of 1800L! (Near 500 gallons!)
    I already have a venturi setup on my 32mm return pipe that injects a hell of a lot of O2 into the water but it's not on the nano scale and just comes back to the surface rather than fully hanging in the liquid.. Nano bubble generators are far too loud, so this is the only alternative I think?! (Please feel free to kick in if you know anything I don't!) ☺

    Would love to know where the OP ''ganjineer'' got with his experiments.. He hasn't kicked in on this thread since December last year! Did you kill your plants or blow yourself up mate?? Please advise! :cry:

    I recently added a power head with an air pump. I may have to bite the bullet and spend the $250 if this shows a significant improvement over the power head venturi setup i have now.

    And how are you going to actually know if your $250 investment is any more effective than a power head venture rig. How will you test that dude?

    I figured i might grab it after my next harvest. Not sure whats better or even how to test now that i think of it. Chances are i will just stick to my current setup.

    Im surprised more ppl or pros aren't testing it.

    Why can't you put your air pump in the same room?
