Seedling starts fit right in the holes without further digging! Screw-on dibbles allow you to easily choose your row spacing along the toolbar, and a set of row markers adjust to mark out your next set of holes. Lightweight design is easy to carry and transport. Choose dibbles designed for seedlings grown in either 128-cell or 72-cell plug flats. Dibbles are required but not included. We offer 128-Cell Dibbles (#6756), 72-Cell Dibbles (#6757), and a Dibble Starter Pack (#6755) for transplanting various sizes of seedling plugs. Holes for adjusting dibbles and row markers are 1" on center. Made in Maine, USA.
