RDWC design/build

I have been researching RDWC systems and came across this system.

What I like about this system is that it seems very easy to put together and since I am planning on building it myself that is definitely a plus. If those of you who have more experience please comment with the potential cons of a setup like this I would greatly appreciate the input.

Thanks

It is what it is.
Very simple, easy to build RDWC system.
They work great.

The cons are that you won't get shit for flow between the buckets and uneven water levels.

If you want to bang RDWC, then do it proper and buld an undercurrent system

the super bubble dwc as shown in the picture flows from bottom to top, so the water is pumped to the bottom of the bucket then has an overflow pipe which is a little bit larger to drain the water back to the res, doesnt this eliminate the issues you can have with rdwc and water levels when using less than 40mm piping?

Your better off just using a large tote/bin to eliminate all the extra lines and complexity's. You won't get the spread of this system but could come close without needing so many extra airstones, air pumps, and lines going everywhere. This is my preference

home depot has 27 gallon totes for $10 ea,these work great for rdwc as I've found..sturdy,easy to place bulkhead fittings on and easy to maintain and most important,dont crack like 5 gals do sometimes.

That is waaaaay to big for RDWC containers. Even when growing trees. I know the containers you speak of, they are great. BTW. Bulkheads are a rip off, just buy the rubber donuts. Vaseline is your friend when putting things together though!

I built one of those systems a while back. They're simple and effective.
That being said, I'm going back to DWC this next grow and I'm building an undercurrent,
as it produces far better results from what I've seen.

That's actually debateable,I have good results using 27 gal totes and water moves very good with a 1200gph pump on top of tons of air to the roots, ea air pump which is a 951gph pump goes to two totes..looking at 8,000 total watts over 12 of those totes..I'm pulling no less than a half p every time ea plant..average about 3/4lb so it's worth the extra effort and time And as for the Vaseline.. right! lol,those suckers are a pain in the arse to pull apart without that stuff,lol

I'm building another rdwc set up again after I finish my current run using Rubbermaid brute totes 20 gallon tores with the top of 5 gallon buckets cut off and 8" net pots on the buckets that are siliconed to the tote lids. Using 3" uniseals .gota love rdwc they always yield when don right

The more holes you put in your buckets, the more chances for spillage. Once one joint is loose, the whole system will empty. Ask around for flood stories and you will get some scary stories. You ever think about growing in a big, like 30 gallon dwc buckets?

Minus putting them together,never really cared for mocking up,but has to be done sometime,lol...used to do the 5 gallon buckets but those sometimes kept cracking on me and flooding the entire room,couldnt figure out for awhile where the leaks was til finished and saw cracks on bottom of bucket :/

Hey drift, I would suggest you move that water chiller outside of your room and hose them.

1. That thing produces alot of heat.
2. The heat is directly hitting your main reservoir and your bucket.

Also, that chiller seems pretty small, what is the size? Everything else looks fantastic. Very clean. Keep up the good work.

Hey there, Thanks for the words , chiller has been moved and doing a different setup now as I am using a 1/2 hp now,that one in pic is only a 1/10,but with water level being 1/3 of the tote size and with flow lines and a timed feed line,keeps the water level good. what I didn't show is there is a 15k btu wall a/c and a standup 18.5kbtu standup a/c / dehum on the other side of the room. Plus there are 2 10'' holes with ducting to respective in/outtakes on opposite sides of room in back corners. the one on the left side is the exhaust and routed straight under house and out the side dryer vent and the intake on the right pulls in all the cool air and is filtered.Again,thanks for the kind words..I will try to get more pics up,but atm camera screen cracked and need to fix it :/ lol

Here is an update on the 27 gal totes.. just 6 plants in these 8 as 2 failed but the other 6 girls are loving it so far

Nice setup.. I bet you are loving it so far lol.. I would be too! If only I had somewhere to grow!

What was the reason for failure? I'll tell you something that you probably don't want to hear, but at least be open to it. After numerous successful DWC and RDWC grows(and a few cluster fucks) I have totally moved on. The pumps, the connections, the air stones, the chillers, the air pumps..FUCK it all.

Hempy baby, hempy. 20 gallon totes filled with perlite and a little coco. A 1/2" hole about 2" from the bottom of the tote.

Slightly slower veg than DWC but same flower time and just the same amount of yield..if not better. We are drying at LEAST 25lbs of dense nugs from 18 bare bulb 1,000. It's just too damn easy dude. Mix nutes, water, and walk the fuck away. 3 days later..same deal.

Anyways, just throwing it out there. Good luck on your grow and I subbed up.
Cheers

failure was due to cracks unforeseen in totes,nothing due to plants hmm..that setup sounds interesting for sure,def going to have to look into that ,cheers!

That sucks. The last Ebb/flow bucket run I had this one plant just looked droopy and got worse. After 3 days I finally found out that something was plugging the drain line.

Here is the hempy thread. https://www.rollitup.org/hydroponics-aeroponics/712994-whole-lot-hempy-whole-lot.html

Haven't put a whole lot of time into the thread ..too busy fucking growing weed. LOL

Going to post some bud porn soon though.
