I made a video of how to setup an 8 bucket RDWC in a 4x8 tent

Airwalker, that's not much of an advantage.
The advantage to just DWC is reduced trouble, not making the plumbing. The disadvantage is you need more square footage for bucket access. If I wanted to stick with DWC and had the square footage, I would buy extra air pumps or a single large one. This is if I didn't want the trouble of making all the plumbing. If growing in a small space, RDWC is the better choice in the long run.

I have a question on the name. Does this work like ebb and flow? how does the nute mix flow, intermittent flooding or constantly around the circuit?

it just recirculates 24/7, in my video i show the path the water takes. Basically , from the reservoir water flows to the nearest bucket and then to next and so on, at the end of the line a hose is attached which sucks the water and dumps it in the res, and the circle continues.

Very few of the members in here using Rdwc have air pumps any more. Waterfalls are just better and easier to manage.

I had a setup with the waterfall as u mentioned but adding a waterfall to say a 48 bucket or 96 bucket setup is not just a pain + extra cost but worst another 48 or 96 points of failure and a major water damage. In any type of hydroponics setup i would say the goal should be to minimize as many points of failure as possible. for my 8 bucket setup i have an air pump that uses about 60watts which equals to about $30 of electricity cost for a 3 month cycle ( its basically nothing.

If this is the case, why does companies like Current Culture still run air pumps with stones in their system?

I think the waterfall method is more of a hobby home grow setup, but if u go big, say anything over 8 bucket setup , the waterfall method might become an issue. As i mentioned, im getting ready to do a 48 bucket 8 light setup and i am trying to reduce as many points of plumbing as possible.

air stones have been keeping fish alive for decades. i preferred waterfalls in my rdwc for less heat and more DO. either way will get you across the finish line.

Not even. its WAY less in cost and not hard to do at all. Plumbing a house is a whole lot more work that setting up a system like that.
Couple powerful inline pumps if 2000gph or so, just bot to explode the 3/4 and 1/2" PVC.

You know as well as I do in RDwC, it's an advantage to not have to buy replacement air stones and line. Plus the air pumps lose their umph over time.

no, i agree with you. my waterfalls probably could have removed skin with as much blast as they had. lol.

Can we see examples of these homemade RDWC water falls?

I linked this earlier

I GOTTA LOSE THE AIR PUMPS! HOW?! Plus my awesome mini DWC :)

That thing is way overpriced. The whole thing sits on a very simple method of splitting the water to oxygen and hydrogen. In big system I’d be worried about the hydrogen gas... I was looking around and saw 2 more very interesting thing. First one called Carmin. I don’t really get how it...

That's cool man. Pretty low-key. I think you'll be surprised at the pressure of mine. i can't remember now, but its some where around 5-600 gph

Some growers use both, putting air stone in a waterfall which is probably pointless when you realize that water can only hold so much oxygen and no more. How about this idea: use water sprayers plugged into an airline, then anchored in the bucket. Air pump sends air to sprayer which creates bubbles in water. No more air stones.

No. The point is to lose the pumps. Sir pumps suck ass and make too much noise.

@Darknes01 thank's for the great video! Saved it to favourites. I'm a newbie and this was really informative, especially the maths behind what pumps are required etc. Gonna have to try rdwc for sure! Just need to get my head around ppm etc and how to use/detect the right amount of nutrients in a hydroponic solution. Keep making videos please!!! :)
