Fluid Funnel to Fill 4x4 Inch Garden Plant Nursery Pot Trays with Seed Starting Potting Soil
It's great when you have a nursery table that has a screen mesh so you can make a care-free mess when filling pots and trays. You can then just sweep up and re-use whatever falls through. That's a great system, but if you're concerned about being more tidy, I've found that a simple funnel works great to direct potting soil in a measured way into pots and trays.
