With an attitude like that, if I was the one to be making it, I would have failed from the start. Like doer said this is not a place to sell stuff, you ARE selling something, do not claim you are not when you ARE. We do not want this forum full of your adverts that would just be blocked with an adblocker anyway.

We are a community that helps each other. This very post you are on is a free for all DIY post that anyone can build without giving the OP some cash because it is his idea.

Please take your 'idea' somewhere else, perhaps build your own website and throw thousands of pounds/dollars or whatever into advertising that no one will take much attention of as no one knows what the idea is. It just sounds like you are making very over exagerated claims without ANY proof apart from some sales gimmick patter to try to sell your 1 year away idea that you have apparently been using for years??? Show us pics so we can try to build it ourselves, you DID post on someones DIY thread trying to sell, so do the decent thing (like i already said) and show us all the parts and we will build it for as cheap as you have built it. That way we wont be lining your pockets with cash for sports cars or expensive holidays.

If you are not willing to post a DIY tut for it, then I have said all I need to say and wont waste any more time replying to you.

EDIT: Last but not least, show us pics or it never existed! Simples.

But I'm not a scammer pal. I have more knowledge in the tip of my finger than you could ever have. I didn't get feisty because you told me I wasn't allowed to advertise. I got feisty because you accused me of offering snake oil. You can't just accuse people of anything because they violated one rule that has nothing at all to do with your accusations.

Fisty smisthy. You got your chain jerked and you feel hurt. I can and do anything I want, here. But, I don't advertise. I invent and give to RIU DIYers like myself.

Hmmmm....don't really see a new concept here. But, I do like the technique of adding some circulation. I grow in a bathroom and you can't beat the water and drain.

I'm doing much the same thing, in a bathroom, in buckets and circulation is a problem. But, I use a pump to handle both the lift of the water to expose it to surface and mass transfer of O2 and circulation. Sorry, but I debunk the concept that tiny bubble add O2 to the water. They don't.

This is not me making it up. It is well known in fish keeping and waste water treatment. Our city switched out of air bubble 15 years ago, for sewage. Waterfalls? Spray in the air? Same thing. Not as good as this.

It is called flooming. I have thread on it here. So, if you aim the entrance of the water jet 45* to the surface to lift bottom water for a wide push of atmosphere, you get O2 saturation and circulation without adding hot air bubbles.

You like improvements? Check out Floooming. :) Water saturates very easily with O2. That is the myth. Nice kit in the bath, though. I like it.

My RO water is almost saturated in the barrel. I've tested it.

I use it to keep my water saturated. I don't use airstones and air pumps any more.

nice,

I just build a 8 site, using this exact setup. Going to use canna nutes. Still have to find a good strain.

I hope i can dail things in. Any tips? I usually run nft

Hard to see from pics but... does the feed line and the waterfall elbow in res come off same pump? My res is below the tent ...how do I keep the water levels at the right height in pots if drains are on bottom of pots? It Seems too much water in will be overflow too little and it'll exit faster than it will fill? Somebody fill the gaps for me please..Cheers

The system you are talking about is not the same as this. This depends on a flat floor. This depends on level surfaces of water.

If your res is below the grow you can't safely do rdwc. I say safely because I have experimented with pumps, valves and floats, siphons, even. At some point, a slight mismatch of pressures happen, regardless, pumps are not exactly matched, etc, and the high surface will over fill the low surface container.

If you have two water surfaces you need to do fill and drain, ie ebb and flow. Pump it up and let it drain back. No other way I know to do it, fail safe.

Gravity drain(res lowest each station respectively slightly higher) pumping from res back to top pot won't work? Cheers for the help

Describe how it is fail safe. If you can do that, then it is....if not, then the idea needs some work. :)

Power out?
Root clogged return line between sites and to res?

If you have a reservoir that can hold it all is only one side.

If you are linking descending containers, and pumping back up, then you could have situation where the 1 container has to hold all.

A clog in the first join, drain it all into the res where it is pumped into the top container, which is either big enough to pump it all into or begin overboarding the nute solution.

Then when that is done the pump burns up.

So, this is true for all containers in the fall line. Each join can clog, strike that, WILL clog, and the upstream has to hold all the water.

Then when that is done the pump burns up. :)

So if all containers are the capable of holding the entire circulating pond, what is the use of circulating?

Believe me, I have been all through this. I had a 12 bucket udwc going for a while, but many problems with that much water. And my big Ah Ha was 10 gal separate totes for reservoirs. I have 3, now. They need to be at different concentrations, constantly, right?

#1 - second month of Veg (first month is hand fed)
#2 - first month of Bloom
#3 - second month of Bloom

The girls are planted into a 2.5 gal, square rose bucket, and there they stay. The buckets move between reservoirs always in process like an assembly line.

View attachment 2919266

Each tote has a hole in the, lid middle, for a 4 inch net pot, but that is just the drain and utility hole. It has filter material and is a the low point of tote lid. It also takes power and pump hose up and the filter fibers seal all that to light but not drain water.

The rose buckets are square and just fit a pair on a tote lid. I hook the feeder rings to the pump in that res and set the timer for the top feeding hydro schedule in 50/50 coco coir and hydroton.

I wanted to do away with separate containers or at least connect the existing. . fluming seemed best way to go. .I don't want to complicate things...just wanted more control over my res(temps,do, pathogens ect) not more problems thx

Well there is NTF. A long pipe or something, with grow sites. Water is passed to the top, but not much water. Roots are in a mat along the trough. A pump failure will let the roots dry out, so not really fail safe unless there is back up power.
