I have posted this on another thread but thought it may help if I made a new thread. I have 10 x 8 litre coco pots getting fed 5 times each day.
This is my 10 plant watering system. The main pipe is 13mm, delivery pipes are 4mm. Each delivery pipe has a small T so the feed comes out of 2 pipes either side of your pot. I have my feed tub outside of my room. Digital timer eBay item number:282265319285 The fittings are available from ebay or somewhere like Growell. They are just push on. The barbs into the main pipe just push in. You will need a hole punch to make holes in your main pipe (£0.85p) to insert the barbs. I have valves on each delivery pipe so I can regulate flow or switch off completely. I also have a on/off valve on the middle line as I don't always put plants in the middle depending on how big I let them get.
Don't forget the anti syphon. Put a barb on the main pipe next to your tub with a short length of 4mm tube on to guide the water back into your tub. When your pump switches off this will let air into the system and stop syphoning.
Don't skimp on your pump size/power from memory mine was Hailea 2900lph I had to buy a 25mm-13mm Pipe Reducer and a short length of 25mm pipe to make it fit onto the 13m pipe.
Hope this helps
