Installed T’s to split the flow. First time using these 4" cap dealios on 1gal pots. They work. The pump is 400gph. I prefer shorter bursts of more volume .vs. drip or slow flow.
With 2 or 3 gal, I run dual lines to each pot. If I ever need more pressure, I toss in a bigger pump.
Bottom left hole. Thats my intake, with an ecowitt wireless sensor placed in the airway.
