We have just learned that there are some Ups-a-Daisy inserts on the market which have a smaller outside lift hole. This hole measures 7/8” in diameter (vs. 1 1/8”) which is critical to the size of the PVC you will use for your fill tube.
Here’s what to do. If you order your Ups-A-Daisy from the manufacturer, contact them at 1-815-477-0656 or info@ups-a-daisy.com to specify that you’ll be using the insert for a self-watering container. That will ensure you get the one with the hole that exactly matches what’s in the book and you’re “home free.” If you get your inserts from your local garden center, don’t purchase your PVC until you measure the outside lift hole. If it measures 1 1/8”, you’re fine. If it measures 7/8”, then you need to substitute ½” PVC and #15 O-rings for the ¾” PVC and #18 O-rings specified on pages 17 and 20 in the book. In any event, don’t purchase your PVC/electrical conduit and O-rings until you know for certain which size hole you’ll be working with.
