KORAM 10 Sets Seed Trays 60 Large Cells Clear Seedling Tray Plant Starter Kit Growing Trays with Humidity Lid and Base for Greenhouse Seed Germination (C6)

It's my first time planting seeds and I planted 1000+ of them using these containers. On the seed package I was told to plant 5-10 seeds per cell, so these fit the bill perfectly. I planted them not even 6 days ago and I already have 30+ sprouting in these containers.They're not incredibly strong containers but you also don't expect them to be for this price. What they're meant to do is to get the job done and that's what they did. I wanted to use cheaper humidity domes before investing in higher end ones to make sure this is something I genuinely want to get into and it definitely is.Even though they're not "strong-strong," they're definitely reusable. Just don't be rough with them and they'll definitely last another use or two, possibly more.If growing seeds (I'm growing cacti seeds in these) is something you're not sure if you're genuinely interested in or not and don't want to spend too much to find out, these are definitely worth the buy. They're also good for testing out different conditions, making sure certain kind of seeds are together so you're not as likely to get them mixed up, just wanted to start a small batch of seeds, or even getting them started for a friend to give to them and help them introduce themselves to growing seeds.It's also worth noting that the tools it came with were extremely helpful. I also got the clear version so I can see when the roots start filling the bottoms, which won't be for a little bit.And I spent so much time filling the cells with soil when I THINK I could have just filled the domes with soil, connect them to the cell bottom tray, and flip them so the soil is now in the cells. Probably would have to gently rinse the domes but I think it would have been a lot faster had I done that. But maybe it wouldn't have worked out that well. I'm definitely going to try it out next time but just thought I'd throw that idea out there.100% worth buying.

I used these to sprout seedlings in a makeshift bookshelf setup (pictured). These were the right dimensions for fitting/moving trays around due to uneven lighting. Lids are tall enough to allow for some growth (great if seeds sprout at different times). Vents on the top are a nice feature to prevent mold; they are just a small circle of plastic that pops into an indent on the top of the lid, and rotates like the top of a salt shaker (pictured). Simple, works.I used Jiffy peat pellets to start the seeds in; however, Jiffy peat pellets DO NOT fit inside the sectioned-off plastic inserts, so I just put the pellets directly in the trays (which worked well.) The sectioned-off plastic inserts are ok for loose soil, but are made of thin plastic and are one-time use (they will break when you push the seedlings out for transplanting.)The bottom trays and top lids are made of a plastic similar to blister packaging - not as rigid as a typical takeout food container but also seemingly less brittle. I didn't have any break on me, but I DEFINITELY wouldn't leave these exposed to the elements for any extended time (they are more suited for the indoors, artificial lighting, normal temperatures and handwashing.) They're also so light that they would blow right away with some wind, if your soil was dry.The fit of the lid to the bottom tray isn't perfect; some condensation inevitably leaks out, so put these on something you don't mind getting a little wet.I actually ended up using the tools provided (shocking!) One tool is labeled with inch/centimeter measurements for seed depth, which was SUPER useful! You just poke a hole in the soil with the tool up to the measurement on the seed packet. The tags are OK; they have a bad/corporate looking logo on them which makes no sense, but is easy to cover with a label. See picture.Great deal for what you get, great for urban gardeners sprouting seeds indoors. Hope they last another season!

These domed seed trays are a fantastic buy. The small size gives you the freedom to squeeze them into small spaces, to start smaller batches of seeds, and to maintain different climate conditions for groups of seedlings.A cheap and space-efficient way of setting up these little greenhouses is with a laundry cart. You can fit three trays per shelf on the  Honey-Can-Do 3-Tier Laundry Cart . If you have space for a more traditional layout, you can fit 6 of the black inserts into a 1020 tray. I have succulent propagations set up like this, and I use the leftover trays and domes to house African violet propagations in separate 2.5" pots.Update: I've used these for about a year now. I'm still very happy with them. I have used them for multiple rounds of seeds, as carry trays for other pots, as drip trays, as small baskets for clippings, and so on. I've washed them, bleached them, sprayed them with the "jet" setting of a garden hose, left them out in the elements, thrown them about, filled them with gravel, and generally abused them without care. I've used the inserts to hold peat-based soilless potting mixes, coco coir mixes, and long fiber sphagnum moss.Of the 30 tray+cell+dome combos, only one of the cell inserts has cracked (though others are discolored) and just three of the white plastic trays have developed holes in the corners. The cell inserts are no big deal. Because they're are standardized to fit in a 10x20 tray and are sold in hardware stores in the spring and online year round, the inserts are very easily replaced.The trays, of course, are the bigger loss. The ones with holes are still useable for everything except as bottom-watering reservoirs. Two of the three have just pinprick holes, so I may put a small dab of silicone caulking to see if that fixes it. The third is in worse condition. The corners are clearly the weak spot on the trays. I can see them slowly wearing thinner. If you use these as intended, this should not be a problem at all. I'm doing all kinds of things to wear the plastic down on these including repeatedly sliding the trays across rough floors while they hold heavy pots, and squeezing them into small places, crunching the corners in the process.

Thin plastic but sturdy enough for planting. Unfortunately it was pretty hard to get the seedlings out for replanting - if they are root bound and a bit dry they fall out easily enough when you tap the bottoms, but otherwise you have to push pretty hard which means the seedling falls out of its dirt and gets mangled, and also the seedling tray gets a bit crushed. At that rate they'd last through two to three plantings at most. Not worth it.
