5gal vs 7gal pots canna coco

[Ca++]

Have links to a good diy setup?

3 phase pumps, the latest thing.

Well I'm gobsmacked. The 17 meter 24v a few of us have. It will provide 675L and still hold a bar.

That post takes a good walk around the houses. Have a read and shortlist the important aspects of your system. Then start a thread for help, and we can all add some of what we know.

Need an idea of pot size and number, to estimate the number of drippers and the flow rate. From there we can choose the drippers and a suitable pump. I guess you have a mixing tank. Some method of run off collection is needed. One that pumps out the waste for you. An idea of noise concerns is useful. Perhaps have a look at your pots and space, to figure draining them and walkways/pipe routes.

I really like the hosepipe based systems, using barbed connectors, and small plastic manifolds that split the 5mm off the 13mm. Reusable stuff that flows enough for most rooms.
I don't like the unruly hard pipe that you puncture for interference fittings. It's not a 100 meter greenhouse.

We all have ideas for you to look over. Do some reading to pick up the general terms being used, then start a thread. I will help you along with my version of things. As will others.
