RooTrimmer 10 Pack 1020 Trays, Extra Thick Heavy Duty Seed Starting Trays - No Holes, No Leak, Reusable Propagation Flats for Microgreens, Seedlings, Plant Germination, Fodder and Transplant

These trays are great. They are heavy duty and will last for years in our greenhouse.

These are really sturdy trays. Can carry 15 transplants in peat pots with no problem.

This is my second order for the extra thick seed trays. They are worth the cost as they do not crack and develop holes like the thinner trays.

I give these trays 5 stars for being heavy duty and what I was looking for. Something I found is my older 1020 trays do not fit inside the new ones. I’m using other inserts so I’m still happy with the trays.

These aren't your local flimsy jiffy cheap 1020's. They are heavy duty, stiff trays. Highly recommended.

Thick, sturdy, very happy, so much better than big box stores, worth it.

Thick and durable, holds 18 cups. Just right size for my shelves under my grow lights

Good strong sturdy trays. Reusable for sure.

Merci pour ces plateaux qui sont parfaits. Taille idéale pour mon presse mottes. Plastique solide qui ne plit pas. A voir sur la durée.

Buen calidad. Fuerte y perfecto para mi patio.

Sturdy trays, they are way thicker than I was imagining. Will be buying again, great quality for the price

Tougher than the cheaper ones at most big box stores. One of these trays had the corners smashed in likely from delivery (minimal packaging). It was still usable because of the better quality. A little pricey but worth it!

Update: They were great during the early seedling stages no complaints. As the plantsgrew and I up-potted the weight became much more in each tray. Several have cracked dead centre causing me to drop trays full of seedlings when it happens and losing seedlings. I still think they are better than most trays but you need a hand underneath when moving, pulling in and out once the plants are closer to transplant time. I switched to carrying them in and out on a tote lid to help eliminate issues. But moving them on and off that lid still more cracked. Most of the cracking happened after being outside so perhaps the sunlight played an issue in breakdown only one cracked before hardening off started. Overall they are better than others I have tried. I have ordered two sets. They are for sure sturdy. Any gardener who has used a 10x20 tray knows they are usually flimsy and not sturdy. These you can hold with one hand (See pic) full of plants with no fear of breaking. They are thicker but heat mats still work with them. They have a nice thick border along the top edge which I think is how they stay so sturdy. They have these ridges which provide stability but also work great for bottom watering too. The first set arrived not properly packed in a large box with only dented corners, the sleeve was ripped, and there was what appeared to be hard water stains in them and dirt in the lower trays but not the top one. I thought they may have been used this is why 4* vs 5*. The second set arrived properly packed with packing material in an appropriately sized box and no stains or dirt. The sleeve around them was still ripped apart. I am not sure if the warehouse people are grabbing them that way leading to the breakage. The reality is these are by far the sturdiest 10x20 trays I have purchased and I am putting plants and dirt in them anyway. I still would prefer they arrive looking new and not like someone attacked them first. But they are great trays and I would and did buy again. My Luvcosy silicone seed starting trays fit perfectly in them too. Work on your packaging/packing to make sure they arrive like new and you will have a 5* product for sure. They are great trays and that is the bottom line. They work well and they will last for many years I am sure.
