Hydroponic needs your help

What pot size should be for 3-6 plants in a 1.50x1.50 tent and how big the nutrient tank should be? I have 90 liters in mind but I think that is too big for 3-6 plants in 7-11 liter pots or am I wrong incorrect ?

It will be a hydroponic NFT and drip system hybrid where I also need help with how to set the timer for when, how often and for how long the plants should receive water. Can somebody give me advise?

I dont think pot size matters that much with hydro. I have seen trees grown in 6" rockwool cubes, with nearly constant drip. I used to grow in 3" net pots in 5" vinyl post cover rails. If you are giving the plants enough nutrition, they will grow big in a small space.

But let me page @FicklePickle to check his opinion.
