new diy rdwc build can i get some advice

RDWC=
Recirculating
DEEP
Water
Culture

Yours is not deep; it's very shallow and continuously running, which make it 'NFT';

Technique

Not saying it isn't awesome, but I am saying that I am the misapplied terminology TERMINATOR!

Lol. You are correct. Well, sorta. In an NFT system there wouldn't be 5 inches of water in the bottom, or air stones. Hybrid?

Hydroton is the original NFT medium, intentionally designed for the water to run down the outside of all the pebbles, aerating as it goes.

I have a sorta rwdc....lol. It's a tube system with 5x5 inch by 8 feet pvc posts. I use flood and drain fittings to control the water level. 3 air stones per tube. 40 gallon res. 1/10th hp chiller. 2 1000 watt ballasts, and 2 400's in cool tubes. 2800 watts total. All in a 5x10 tent. Although the chiller isn't necessary right now. My plants are loving it so far..but just clones so far.
My recommendation would be go sog or scrog. Higher numbers, but less veg time.
Good stuff. That's the exact style I started with when I started out. I was growing basil & tomatoes on my patio then graduated to real herb. They work really good, just lots of root build up. Clone to flower works best in those & definitely scrog. Pack'em in tight with little or no veg time at all. Lolly pops of green sticky goodness.

I made the switch to RDWC to accommodate a larger root mass. Here's a couple recent pics of one of our licensed MMJ flower rooms in Michigan. The first pic is the day we transplanted them from a 30 day veg. And the second one is that same garden a week later. It shows that with an increased root volume & lots of air to the roots, growth rates are super charged. I'm hooked on RDWC.

I'm a big fan of RDWC, myself;

so really though whats the verdict. uniseal or ebb and flow fittings. I'm getting ready to set up a 6x6 tent with 1kw for a six site homer bucket rdwc. Im not sure i'd easily be able to accommodate multiple fittings per bucket. I've seen some folks run the ebb and flow fitting with the screens on them. are these effective enough to keep roots out. I just find myself cringing at the thought of rigid piping and the lack of flexibilty for multiple strain runs. find myself sliding buckets around as is to try and maximize canopy brightness. although i guess a cheap light mover would do about as well

Threaded bulkhead fittings. You answered your own question when you said you wanted the flexibility to shift things around.

Get these;

I use the flood and drain fittings and flexible black water hose. This allows movement of the tubes. However I don't think they would work on a typical 5 gallon bucket since the surface of those are rounded. I would say go with large grommets and flexible hosing. Also, the more flow you have going from bucket to bucket, there's more of a chance of the system getting clogged.
(Hydrofarm makes a flat sided 5 gallon bucket that would work with flood and drain fittings perfect.)

I keep hearing this, but it's not true! Drill the hole, screw the bulkhead fitting in and the fitting flattens the plastic. No leaks, no problem!

word. so if I grab some of those 1" for outlet and some 1/2" for inlet i'm assuming i just get some 1"id and 1/2" id vinyl tube to accompany it. Basically I guess I'm asking if the barb would fit snugly into the vinyl tubing or if there is a more appropriate diameter i should get. I hate wandering around our local home depots with a handul of fittings trying to part together crap so im considering skipping the local stores and just order it all. well except for the threaded elbows unless you happen to know the standard internal threading size for the 1/2" fitting. lol

Have your hydro store order the threaded bulkhead fittings; they're very good for the money. Standard 1" tubing should fit snugly over the barbs. If you have a problem, use a hose clamp.

I don't use airpumps or stones. Instead, I use a 1" line out from a single waterpump in my control bucket. Along this line I place 1" x 1" x 1/2" funny pipe tees, one for each tubsite. Half inch line from there to the netpot and a half inch elbow fitting as the emitter. Cap the end of the 1" outlet line from the waterpump and ¡voila! Instant water distribution manifold!

So you are feeding water to the top i assume? But no airstones in the buckets? Just recirculating? Or am I confused?
