Q: What is air pruning and how does it benefit my seedlings?

A: Air pruning occurs when root tips reach the vertical slots in the punnet walls and are exposed to air. This stops the roots from circling the bottom (becoming root-bound) and forces the plant to develop a dense, fibrous root system. The result is faster growth and zero transplant shock.

Q: How many 6-cell inserts fit into a standard 1020 tray?

A: These inserts are designed for a precision modular fit. You can fit exactly 12 of these 6-cell punnets into a standard 1020 tray, providing a total of 72 individual cells per tray while allowing you to move small groups of plants individually.

Q: How does using different colors help with crop management?

A: Choosing different colors for your 6-cell punnets is an effective way to tell your crops apart at a glance. By color-coding your varieties (e.g., blue for kale, green for lettuce), you can easily track planting dates or species without relying solely on plant tags.

Q: Are these punnets reusable and how do I sanitize them?

A: Yes. Built to last 10+ years, these are heavy-duty injection-molded punnets made from #5 BPA-free polypropylene. They are dishwasher safe or can be sanitized with a standard bleach or vinegar dip without warping.
