Watering Cups? - Page 5
No, the basic cups don't have adapters, you can install those directly, I was happy to pay for adapters so I could use them immediately.
I bought the cups on Ebay with the 1/2" sleeves, I found an awesome idea on Pinterest that shows how to make a watering system with a bucket and a couple of other 1/2" pieces of PVC pipe. But I forgot to pin it so I will be going off of memory, I think the cups look great. I am even going to try them with my chicks to see if they can pick up on it from day 1. If I find the video I will repost it on here.
