Frequently Asked Questions

Q: What tray size does this insert fit?
A: It fits standard 10 x 20 in trays and flats. Check your tray's inner dimensions if it is not a standard size.

Q: How many plugs are in one insert?
A: Each insert holds 50 plugs. That gives you a full tray layout in a single step.

Q: What does pre-filled insert mean?
A: The plugs arrive already seated in an insert, so you do not fill or arrange individual cells. You place the insert in the tray and start planting.

Q: How is an insert different from loose plugs?
A: Loose plugs must be placed one at a time in a tray. An insert holds all its plugs in position, which saves setup time and keeps spacing uniform.

Q: Do the plugs have holes for seeds or cuttings?
A: Yes, the plugs have pre-cut holes. You can place seeds or cuttings directly without making your own openings.
