Size of the Tray

In the world of seeds, size does matter. Think about how many plants you dream of nurturing and how much space each seedling requires to flourish. Remember, seeds need room to stretch their roots and grow. Consider this as you select the tray cradling your future plant babies.

Cell Depth

Just like us, seeds need room to grow. They yearn to extend their roots into the rich, welcoming soil. Look for trays with cells deep enough to allow your seedlings to grow unabated yet shallow sufficiently so their delicate tendrils can access the life-giving warmth and light above.

Material Durability 

A seed tray is the nursery of your plants, and it should be robust and reliable. Look for trays made from durable, high-quality materials. Imagine the tray as the guardian of your seeds, standing strong against the trials of time and weather, defending your seedlings as they grow.

Drainage Systems

Plants, like people, need balance. Too much water can be as damaging as too little. An efficient drainage system in your seed tray will ensure your seedlings get just the right amount of moisture, preventing drought and overwatering. A good tray strikes that perfect harmony between land and water.

Ease of Transplanting 

The time will come when your little seedlings must leave their tray and venture into the big wide world (or at least a bigger pot). A tray with a design that eases this transition is a boon. Some trays even come with individual cells that can be pushed up from the bottom, making the process a gentle experience for your young plants.
