1010 Trays for Microgreens, 10 Pack of Black No-Hole Flats | Heavy-Duty Shallow Plant Trays for Commercial Growers

Very sturdy and absolutely perfect

Ordered a 20 pack of these for experimenting with Microgreens and planting seedlings in the greenhouse. They showed up within a few days and are very sturdy. I have since grown some batches of microgreens and they turned out great. Not to be captain obvious, but these trays are designed to hold water as they have no holes, so for side edge watering a crop of greens, these are great as the water permeates the root bed and soils moving along the bottom of the tray. This enables wicking of water up through the roots. I have also used these trays to hold smaller seedling planter 6 slot trays allowing me also to bottom water those by adding water just to the 10"x10" tray. Simple I know. I like that these trays are thicker and sturdy. They don't flex a lot at all and the size is handy for the greenhouse shelves and benches. 20 should be plenty for a while. Also, these clean up easy since they are not huge.

Super nice heavy quality.

I have been using this company for years as a teacher, to stock my classroom due to the excellent quality. Now retired, still playing, so I ordered for myself. The wrong product was sent, and when notified they immediately sent the right one. Their excellent, Pleasant customer service matches their products.

Thick material, groves in bottom connect allowing liquid to cover entire bottom of tray. When using with the slotted tray they stick together making it hard to pull apart. Easy to clean and will last a life time with minimal care.

Looks like these trays were made well, but they are the same tray both with and without holes. This means they do not nest together very well unfortunately. They either stay up a bit too high or when pressed down for the proper fit become very tight to open and bottom water for micro greens. Disappointed for the premium price more care was not taken in the design.

Bootstrap Farmers trays are the only one readily available commercially that I can use here in sunny Tucson AZ. They are not only thicker than the usual inexpensive trays but, more importantly, they are made of PP (Polypropilene) #5 plastic that is well suited for this application and lasts forever VS the cheap flimsy trays that are not only thin but catastrophically made of PS (Polystyrene) #5 plastic that breaks down quick and melts and frays all over the place when exposed to UV (sunlight) no matter how thick they are. So fellow gardeners know your plastics and buy these or equivalent PP trays (when you can find them). These BF trays are more expensive but last forever and ever!

Love the strong construction of the trays. I think they will last me many years. Looking forward to adding more pieces in the future.
