Zero heat Virtually no water surface disruption. The bubbles created are so small they look like smoke and too small to even break the surface so it stays suspended in the water. There are just a very few "hydrogen" bubbles created they are regular large bubbles and they break the surface and...

No clue, just plug it in and toss the emitter into the water. http://www.o2grow.com/

Hades Down is to bring the pH down to 6.4 Although now I just use coconut water and aloe vera juice added to the water to bring the pH down, works perfect. There just needs to be something in the water for the electrolysis to work.

I use Orange Peels. Of course, I am not hydro though, just oxygenating water to use for soil. Supposedly aquarium dechlorination drops work.

Iam in SOIL. Right now I am watering everyday with 2 gallons. I run the emitter about 20 minutes in 2 gallons add nutrients then water plants. So for my situation it works great. For hydro, I don't know. I do know that with my horrible tap water even after filtering out 99% of the chlorine what...

Well working great for me in organic soil. I use just a splash of Hades Down in the RO water and the emitter puts out a nice fog of bubbles. And zero chlorine is created. Then I just mix in my nutrients and it's good to go

You are correct in your research. I will tell you what I have found out so far. I have switched to RO and even some Deionized water that I have been buying from Wholefoods for .39 cents a gallon which frankly is cheaper than buying filters. The RO water has PPM averaging about 0.012 the...

Hard to say, I hear that bubblers actually take out DO the emitters put in. But just pumping to a waterfall I wouldn't think so. Only way to really know is test it. The only thing I am disappointed about with the emitters is that it creates chlorine if any salt of any kind is in the water...

and this can put close to 20% into the water Vs the 6-7% that air stones dissolve into the water, so more than double. Then since the oxygen "created" is so small and heavier then it doesn't break the surface and stays in the water (you can visibly see this) with air stones you get at best...

That looks great, I hope my first grow is anywhere close to that nice.

Thank you for the info. So sounds like 5 per heatsink would be about perfect really, that's about 29W/ft2 should run nice and cool. I just figured out the cost to run the light and should only be about $11 a month at 16 hours a day and about $8 a month at 12/12. So this LED might cost an arm and...

Thank you for the response. I thought about the 1050mA but I guess that I misunderstood how much I could get away with on the heatsink. So I can put 5 CBX3590s 3500K 36V CD @ 700mA on each 44" x 5.88" heatsink? I am in the US so running on 110v. Then to get great coverage, plenty of PAR/W etc...

Noob here, last time I grew was back about 1979 LOL. Then honestly the best way to grow was I took a years worth of bag seed which filled a 1-gallon zip lock I went to a really out of the way area that had a seasonal stream, it was running all winter and up til about May then started to mostly...
