500 Cells 54x28 cm Seedling Plug Trays - 10 PCS 20x10 inch Reusable Seed Starter Container for Nursery Growing Plants Propagation Germination GDPL02L50B 【47x47MM Grid, 90MM Depth】50 Grids/Tray

Great for transplanting seedlings, long for a good root system, also made to last.

In case you’re unsure here’s a can of Pepsi (other fizzy pop is available ) for perspective. As you can see, the cells are mahoosive. Could plant a tree in them! Solidly made and probably fine for large plantlets, just no good for seedling tiddlers. Back they go…!

Good quality trays

They hold compost and you can plant seeds in them

Bought for my carrot seedlings as a lot to plant all at once. Seem pretty sturdy for the size. Should be able to use them for several years.

Cheap, flimy rubbish that will maybe last the season . When it comes to module trays, you get what you pay for. This will sadly be more plastic for landfill in a couple of years even if I’m really careful with them. I’m going back to Charles Dowding trays. They are the best and will last you for years x

Too pointed so dont hold moisture - good and sturdy but as they are cone shaped there is not much soil (if any) at the bottom so they hold no moisture - and with modern no-peat composts they dry out all the time - (if you look underneath there is so much air space (as they are cones) no wonder rhey dry out) - so cannot recommend.

My harvested seeds are already coming along nicely. Bought these together with a little plastic greenhouse. Bring on Spring :-)

Seems like a very sturdy and solid product for seed starting. I'd hesitate to use in full UV given the composition of material. Head mats and lights should enable the product to last for multiple years. Currently in my first year of operation with aforementioned conditions. Solid product. Matches with a 1020 system to water from below. Have yet to transplant from this seed tray just yet but it seems like a simple sharpie poking upwards will do well for that. Would buy again to build out for the home gardener!

Super fast shipping.I'm using these trays to grow citrus seedlings to use for grafting. My germination rates for the seedlings vary according to the varities and condition of the seeds. So, I try to germinate as many seeds as possible.I usually use these trays in my first step to initially sow or plant the seed in the potting mix.When I first started using these trays, I started off with 50 cell 5x10 trays. Those worked well, but I soon needed to repot the growing seedling in bigger containers. I found that I needed to repot the seedling into an intermediate container, before potting into final 4'×14" container.I later found these bigger 32 cell 6×8 trays. Because these new cells are bigger and deeper then the cells on the 5x10 trays, I'm now able to eliminate the intermediate reporting, and go directly into the bigger containers.

Great for starting your seeds indoors. Fit perfect in an indoor greenhouse.

32 cell. Wow, these cells ARE huge. It’ll be nice to give my tomato and pepper plants all this room for their roots when the time comes. Flats fit in bootstrap farmer heavy duty trays no problem. The flats are not the thickest or sturdiest but by god the cells are the largest I’ve been able to find so I have no complaints.

Great tray for cuttings
