but how about getting a few lengths of 1/2”PVC, making a standup, lay other runs of 1/2” pvc across the tops of the cups, mark the center of each cup, drill a 1/4” hole at each point then run a straight piece up higher than you expect the canopy to go, put a funnel on top and let it drain down into all the cups, I did general construction for 15 years I bet with about 50’ of pipe (5 pieces) and a bunch of elbows and tee’s and some PVC glue I could set something up lol. I like to Macgyver my own stuff whenever I can lol.
You’d be able to slowly water them all at once,
I’d say setup some sort of drip setup but the 100 tees to split off at each cup would cost as much as a new light lol
