RSWC, NFT, or Low Flow Aero and even flow supply

What the most effective setup to run in hydro tubes? I'm most interested in experiences and links.

Recirculating-SWC and NFT have the downside of needing to water the plants until the roots grow down into the water flowing in the bottom of the tube.

Low Flow Aero avoids this by providing water to the roots while they are still only in the netcups, but introduces more failure points with a more complex system.

Which is really more effective?

My other question is about creating even flow in the supply pipes, while providing water to tubes that are on a slant in a stadium style setup.

Having the supply line (bottom grey line) run on a slant creates a problem with maintaining even pressure at the top vs the bottom of the system if the supply connection is placed in the middle of the pipe (as the central red arrow at the bottom indicates). Maybe moving the connection up towards the top would even out the flow?

Would an even supply line (top grey line) suffer from the same problems in pressure because of the different drop down heights to the tubes?

put a valve on each line then you can control the flow to make sure each line is even , thats what ive done to my buckets
EASY

A hybrid of 1 and 3 would be a modern aero flow. The most effective method is to keep the water level up to the bottom of the net cups.. If doing veg in a aerocloner you only need to feed your tube from one end, as the roots are already long enough to reach the water. If doing veg in the tubes I'd use the sprinklers (to feed the roots) as well as a feed from one end, just to keep up plenty of water movement. But either way, keeping water level to the bottom of the net cups is a must IME.. Also plenty of water movement to keep up DO.. I find massive growth rates this way... Valves would be best for regulating flow. Peace BL

IMO the LP aero system kicks ass. You just have to think about having access to all parts when designing the system. The sprinklers:

About the level flow. Using small nozzles maintains the pressure in the system, and would make it much easier to do.
Buy a pump with a good lifting height, run pipes in full dimension from the pump all the way up.
The pressure will be 0,05 bar lower if the buckets are 50 cm higher, but if the pump is big enough it doesn't make a difference.
