PRODUCT FEATURES
Are these 5" x 5" insert sheets compatible with the standard 10" x 20" (1020) carrying flats I already use in my greenhouse?
Yes, each 5" x 5" insert sheet is designed to nest perfectly inside most industry-standard 1020 flats. Simply drop the sheet into your flat and you’ll have eight uniform 5" x 5" cells ready for filling.
How many individual inserts come in a case?
A single case contains 10 thermoformed sheets, and each sheet has 8 individual 5" x 5" cells. That means you receive a total of 80 individual inserts per case.
What are the exact dimensions and soil volume of each 5" x 5" cell?
Each cell measures approximately 4.86" L × 4.86" W at the top and 2.27" deep, providing about 45.65 cu in of dry volume—roughly 1.58 pints (747 mL) of liquid capacity. This is plenty of room for herbs, bedding plants, or rooted cuttings to develop a strong root system.
Do the inserts have pre-made drainage holes for excess water?
Yes. The trays feature precision-burned drainage holes in every cell to promote healthy root aeration and prevent waterlogging, so no additional drilling or punching is required.
What material are these insert sheets made from, and are they recyclable?
The inserts are vacuum-thermoformed in the USA from a black plastic blend containing more than 95 % post-consumer recycled material.
Can I reuse these inserts from season to season, or are they intended for single use?
Although lightweight, the high-density thermoformed construction gives the trays enough rigidity for careful multi-season use. If cleaned and stored properly between crops, many growers reuse them several times before recycling.
What plants are best suited for these 5" x 5" cells?
Their generous volume and depth make them ideal for bedding plants, culinary herbs, leafy greens, and even small vegetable starts. The 5" footprint also offers ample space for finishing larger plugs or pot-ups before transplanting outdoors or to retail displays.
Where are these 5" x 5" grow tray inserts manufactured?
The inserts are proudly made in the United States and meet USMCA requirements, ensuring consistent quality and reduced transit times for North American growers.
