I will add to the FUCK O2 EMMITER comment... 100% agree these are a gimmick and there is more to it.
The majority of gas exchange in terms of o2 happens at the surface since o2 is not easily dissolved in water unlike some other gasses. You are not putting o2 into the water but rather replenishing it. Either waterfall or air stones will work well (personal preference here). Air stones that produce smaller bubbles are more effective and gentler on your root systems but not because they dissolve easier in water, they simply provide more surface agitation.
In regards to the o2 emitters: These BS devices should not be on the market for hydroponics and I will explain why.
The one half truth they provide that has merit is the test where they use a DO meter to show it increases DO levels significantly. Now it does not actually increase DO levels its just that the o2 remains suspended in water much much longer because of their buoyancy and this leads to an increased reading by the DO meter.
Now the nasty fact is when you add electricity to these emitters they react with salts and break down over time dissolving heavy metals into you water which your plants have no problem uptaking... Yumm.
Ya I agree I been doing some more reading on them and going to pass thats for sure and plus I refuse to pay that kind of money every 2 yrs or less also they arent really for recirculating systems as much and I'm going to pass on them as like I said orig too if they was sooooo great and wonderful more ppl would use them as they arent much price diff if you would get a linear air pump anyways like 360 vs $400 but ya forget that.....
Has anyone tried the current culture aqua pore pro xl diffusers and what's the difference between those and a soaker hose as they want $50 ea for them when I can build my own for 10th that price so just curious if anyone has used them and what's the difference if any..
As I did buy all my parts for my bloom setup as that's what I was going to setup and it was going to be very clean and now most likely I'm going with 25lpm air pumps instead or maybe a waterfall setup as I got a cool few ideas that would be pretty sweet if I can get it to work..
As yes I know building a ring around the inside bucket for my waterfall is a bit much but I'm okay with that something could happen and I will be happy I did the extra....so I'm thinkn of finding plastic faucet aerators that's male threaded and I'll put them in each of the corner 3ways so 4 per bucket and I'll have a few holes or maybe misters or something in between the corners and see how that works and make it like a hybrid aeroponic/waterfall/rdwc which may work out really well idk that's why we experiment and test things out........
