I really think they will go great in the 3 or 5gs.
I am hoping to get the perfect flow and be able to use through most of veg and flower to maximize growth.
There is a chance I can fert right through them.
I have been thinking I want to feed every time I water, kind of like hydro guys.
Continuous feeding would seem a reasonable approach for soil like hydro done properly?
The carrot only opens or closes a diaphram to allow water through.
The height of the reservoir dictates pressure or flow.
I have placed my entire 32g brute above the top of 5g buckets so gravity makes flow nicely.

I even ran 2 separate lines to feed each side of the room.

^^ Here you can see the height the water comes in at all by gravity.^
Where the carrot is should not matter.
