The mini trays that we purchased are the best ones I've seen. They are sturdy and reusable. In the end, they will save us money. Besides the sturdiness, the design of the mini trays makes them extremely functional for growing seedlings that can be replanted into the garden or that can be offered to children, who can take the plants home and grow in their own gardens or yards.
The delivery was much quicker than we'd expected.
We will happily order this product again from this company.
