Will be my first hydro grow

i am switching from ebb and flow to full DWC system. the growth is amazing in the dwc compared to ebb and flow. I have run the same strain in both set ups, both using hydrotron. DWC wins hands down.

I think it depends on what you mean by "easier". I have a DWC from the link above and it works great. But I hate leaks and I think a DWC is more likely to leak than a E&F. Plus an E&F involves a fewer (though not necessarily cheaper) parts

My DWC buckets dont leak. I actually have to keep a 5 gal bucket under my ebb and flow table because it has a leak somewhere. I have to empty about 3 gallons every month. I have a bumbleberry scrog going right now in the E&F table that will be harvested in a week. The tables are getting kicked and going to (4) 5gal bucket DWC system. Thats just my experience with ebb and flow.

For me....It has been easier to grow a large healthy root system with my DWC buckets compared to my ebb and flow tables. And when it comes down to it, a large healthy root system leads to a large healthy harvest.

I love RDWC but am going to be trying an ebb n flow system with 5gal. buckets for the first time. The main reason for this being enf requires a lot less water. In RDWC you have to keep the res, controller, lines, and buckets full 24hrs a day. A lot more work when flushing and more nutes.

I'm not convinced its just the holes. There's an inherent system in putting the hose into the grommets with no sealant. it might work OK for a bit but as you adjust and move buckets leaks develop. In my next build Im using bulkhead fittings, silicon and testing like crazy and there won't be any leaks.

I don't think that's true of aquarium grade silicon. It holds pretty well and I've done quite a bit of testing on them. Besides, when you use bulkhead fittings it minimizes the movements of the hoses so the chance for leaks is greatly reduced. Here's a link to my new setup, testing has shown no leaks :D : http://forum.grassci...tml#post9792435

Sure, using the step bits are popular. But they dont make one large enough for the bulkheads (1 5/8") so I used a paddle bit instead. I've also considered the clamps but they're a bit expensive and I use CFLs so I think I'm going to be OK with multiple zip ties.

Just use an 1/2" Ebb&Gro fitting...
They are like $2 and I've yet to have any leaks when using them fittings over the Uni-Seals..
If you're doing a R-DWC the site tube only needs to be on the header tank anyway..

Maintenance is about the same for both systems during the grow...
It's after when you're washing 80L of hydroton, and that's when you're bitching up a storm wishing you did DWC... :D

IMPO from using both for many years, DWC grows larger plants, but Ebb&Gro produces better medications because it gives more control over water supply... There is no way to simulate a drought condition in DWC.. Ebb&Gro system are also a LOT more forgiving then DWC...


Good luck no matter what system you choose..

+1 for Rdwc , i did have one small leak but that stoped after two days (max loss 100ml) . just make sure your grommets have 3or4 mm cover around the hole and it will not leak no silicon needed.
one more tip.. when you wrap the buckets in alli foil tape do it in strips downward overlapping 5mm, also drill holes first.

I use an ebb and flo table to get the clones ready for the main rooms. I tried a DWC system side by side with a top feed and drain to res system and saw no difference in yield or strength.
I did however end up with a brown slime algae issue that almost wiped out my 2nd attempt at DWC so I got rid of it and have both bud rooms now setup with the top feed and drain to res system I was using in the other room and it is bulletproof and simple.

I wouldn't go back to DWC.

Ya you will get that with nutrients which use biologicals..
But I kind of agree, Ebb&Gro is kind of my "base" system, as in, when I have to put some good medication on the boards and I cannot fuck around, I pick the Ebb&Gro system...

But you will get larger plants from a true DWC system...
Because IMHO, using 5gal buckets is not a real DWC system, it's simply a bunch of bubble buckets linked together by
a header tank...

I've always related DWC to, like a dedicated 10-20gal tote..
But anything under, is again, nothing more than a bubbler (IMO anyway)...
