Features of the Heavy Duty Reusable 4 Cell Plug Tray Inserts
These heavy-duty seed starting tray inserts are incredibly durable and can be used year after year with proper sanitation and maintenance. Ditch the disposable plastics with these sturdy tools!
The cells have drainage holes and air-pruning slits to ensure healthy roots and robust seedlings. The large drainage hole makes pushing the plants out easy to minimize root disturbances during transplanting.
Perfect for up-potting peppers and tomatoes.
Proudly manufactured in the USA with FDA Prime Grade Extra Strength Polypropylene (#5 BPA free) plastic.
These larger 4-cell plug inserts are deeper for growing varieties of crops that need a little more room.
Humidity domes may sit on top of the inserts, but will not fit snug due to their height extending above the 1020 tray edges.

How To Clean Between Uses
Properly cleaning seed starting trays between uses is critical for healthy seedlings year after year. There are multiple ways to do it, but one easy way is to wash them with hot, soapy water and then spray them down with a diluted vinegar solution. Let the vinegar sit for about 10 minutes. Then, rinse. Let the trays dry completely before stacking and storing them for next year.
Optional Acessories
These sturdy plug trays are unlike any others you will use. It is time to ditch the flimsy trays that break their first season! Pair these inserts with a coco coir and perlite blend to create the perfect seed-starting environment. Choose the 10x20 growing trays without holes for most seed-starting applications. Don’t forget heating mats and grow lights to perfectly control your seedlings’ first environment!
Stories From Our Gardeners
"After using flimsy seed starting trays for years, you will not regret switching to more durable ones! The seedlings are just as easy to get out of the cell, but the cell won’t split and crack during the process!"
