1020 Seed Starter Trays and 72 Cell Plug Trays, Thick Durable Seedling Plastic Nursery Tray for TD538 1020 Tray Germination (10 Sets)

If you fill these up you'll have a lot of plants. I don't need that many plants started this year so what I did was use unused pockets to separate different types of seeds to make it easier to see how they do. I always label the seed rows. These are a good size and aren't heavy even when full of starting soil and watered making it easy to rotate if needed. The plastic is sturdy and should be good for a number of years. The drain holes make overwatering difficult though I prefer misting spray bottles. Seed packets usually recommend 2-3 seeds per planting but with this many pockets available I can plant 1 seed per pocket. Since the dirt comes out with the plants when removed I can re-use the full pockets that didn't start. This results in much fewer wasted seeds. If plants are going to be transplanted outside I try to use a rotating fan on low to help them build up a tolerance to wind.

The RooTrimer brand are high quality trays and inserts. I picked up a couple of the 10 pk of 72 cell with the shallow trays about two years ago for use in the greenhouse for crops at the farm. They are constantly in a rotation of germination spring veggies, clean and disinfect, then start cut flowers, clean and disinfect, then start fall veggies and every single one of them is still in perfect condition. They aren’t quiet as HD as the $30 each germination trays but they are more then adequate. And 1/10th the cost. After planting, any spots that had failed germination I smack the trays on the bottom of my boot to dislodge any soil in those spots so they haven’t been babied by any means and are still holding up great, so I just ordered more of them. This time I needed extra of just the trays for cactus seedlings in the greenhouse but the trays with the inserts are only a few dollars more than just the trays alone so I’ve got backup inserts should one ever break.

$25 for 5 trays of 144. I'm set, these are great and long-lasting. Just wish they had larger cells for my bigger seeds. I don't even need these this season as everything is in the ground, but I couldn't pass up this deal.

Very sturdy compared to other ones I've had, they are very much as advertised. Would recommend. goes well with the domes i also got from the same brand. Now i have 720 plant apartments for next year's growing season.

These trays are great -- I wish I had found them before I had purchased the others. Functionality is great! The bottom trays are thick and rigid and the seedling trays fit perfectly into the lower trays. The thickness of the bottom trays make it easy to move from greenhouse to watering area. It is easy to remove the plants once you are ready to plant them. The price paid was much better than most other options. I will purchase these again!
