Leakless RDWC

N.R.G.

Hey everyone!

I’m starting a new grow soon, and I was wondering if anybody had ideas on how to create an RDWC system that doesn’t involve drilling holes in buckets. I’ve been down that road before, and it usually leaks. Don’t want to chance it I my new apartment! I was thinking some kind of top feed system would be best, but I’m not sure how to drain each bucket. Thoughts?
I wouldn't risk RDWC in an apartment. One mishap could cause a lot of potential damage. Like someone already mentioned, going coco would still be a nice increase in yield and is still hydro and it's much safer in your situation.

roots clogged my RDWC pipes:wall:. Lost 75 gallons fresh nutes due to spill over:dunce:. planning damage control to keep roots contained with paint strainer mesh bags. This was outside, i think i'd be more upset over such a spill if it was inside. :leaf::leaf::leaf:

my return pipes are only 1.5" and i have had to pull roots back into each tote.

with growth as explosive as it has become, getting to the plants on the back row in damn near impossible.

does anyone know if these would work or would they end up preventing water flow with roots bunched up and growing through it?

Those strainers just make the problem worse...been there done that. Big pipe and dont go overboard on the pump is the best solution IMO.

yup, i can see the roots all tangled in them.

i think just making access to each plant will be best. that way i can pull roots back into each tub.

My solution to the PITA associated with a bucket system:

No leaky fittings. No separate res. No root clogged lines. Insulated. Works great, and simple and quick to maintain.

I used multiple 1" bulkhead fitting outlets to each 27 gallon tubsite. Eliminated floods due to clogging problems. Flexible tubing makes teardowns and reconfiguring quick and easy.

Waterfalls worked better for me than air pumps.

No chiller, temps stay in the 71-75 F range, plants grew like crazy.

pH in low to mid 6 range, EC 1.4-1.7.

With netpots, the plants were portable, making 'transplanting' from one system to another trivial.

I hated dealing with bulkhead fittings as well. I just never had good luck with them and being in the middle of nowhere means I have to drive 2 hours to get parts (or wait 2 days for Amazon).

The latest iteration of my system uses plastic laundry tubs (utility sinks). This gives me a huge area for roots, bottom is angled towards the drain to help w/ the siphon, and I can use standard drain fittings to eliminate leaks. It's usually a bit more expensive to get the sinks but I was able to find these for $15 ea so I snagged all they had.

Here's how they looked when we were starting construction. I had some left over Lizard Skin, so they are coated in ceramic insulation now, too. (Saved me from bubble-wrapping them and ensures I'm lightproof w/ no heat bleeding through -- even though I run a chiller I wanted to be 100% sure.)

4 Weeks later Update

Although the plastic is ultimately inferior, no buckets have become broken after I put the system on wood instead of directly on grass. The plastic broke before due to stress from pressures of the uneven sunken soil in the yard.

The paint strainer mesh worked for its intended purpose. Roots grew through it but only 4 inches and there are no "pipe chasing" system cloggers.

Totally ready to rinse and repeat next season :cool:

used 2"x10"x10ft lumber, ground contact pressure treated pine right down the length of the system. buckets were sinking into the dirt at an angle causing the pipe to snap the bucket plastic
