Best Plant Germination Trays of 2025

"I bought these trays because everything available locally was flimsy and not suitable for reuse. I was tired of the cheap plastic trays that buckle under the weight of plants. I hope these will last for the next few years!"

"Using these trays has been a dream! The flexibility of the silicone bottoms makes it a breeze to pop out the transplants, and I love the bottom watering feature. I've had 80-100% success with germination this year!"

"This tray was a game-changer for my daughter and me. Our seedlings sprouted almost immediately, and we had a much higher success rate than with other trays. It made gardening enjoyable and rewarding!"

"I’m taking a moment to review because this product is really high quality for the price. I love the bottom watering tray and the heavy plastic cells and top. This will surely last me multiple growing seasons unlike many other seed starter trays. The humidity control spinners on top and the cute little tools that come with it are fantastic. As an experienced gardener, I’d 10/10 recommend it!"

"I love that the clear lids are tall with adjustable vent holes. The base tray is watertight, unlike my old tray that ruined surfaces. I wish the cells were split into more pieces since some seeds sprouted too quickly, but I’ll choose seeds more carefully next time. Overall, they are easy to clean, feel durable, and I’d buy this brand again."

"The cell tray, underlining tray, and clear canopy are all well made with durable materials. I set them on seed-starting heat mats, but condensation builds up on the covering, creating a mess. Water control seems overlooked in the design. While they work under certain setups, I wouldn’t recommend them for indoor use."

"I was pleasantly surprised by the thick and rigid trays, unlike the flimsy ones I expected. Although the seedling pots are smaller than anticipated, I’m confident they’ll work well for transplanting. The included safety-certified heating pad gives me peace of mind. My wife and I are excited to start our seedlings this spring!"

"I appreciate the six trays included, along with the bright LED lights. However, the loosely fitting lids can be a bit of a hassle. The timer issue is minor for me, but I’m excited to test how well the humidity control works with my seedlings!"

"As someone without south-facing windows, I was thrilled to find these trays with energy-efficient LED lights. They are sturdy and perfect for starting seeds indoors. I'm looking forward to using them even after expanding my greenhouse, and I plan to provide updates on my seedlings' progress!"

"I was initially concerned about my cell packs fitting in the trays, but they fit perfectly! The width was just right, and even though they are a bit longer, it gave me a chance to create a gap for watering. To my relief, the trays arrived in great condition and seem to hold my packs snugly while also having drain holes. Overall, I think they’re worth the discounted price!"

"I was pleasantly surprised by the quality of these trays. They are well-structured and reasonably priced compared to the flimsy options at local stores. I’ve decided to become a repeat customer because they really meet my gardening needs!"

"I hesitated at first due to some reviews about flimsy trays but decided to order anyway. My first set was sturdy, but the second set was a huge disappointment. They were so thin that I couldn't carry them with any weight. I hope the company addresses this quality issue. I’ve ordered another set, and thankfully, they are similar in quality to my first set, so I’m increasing my rating!"

"One of the trays arrived damaged, but I emailed for a replacement or refund and was promptly refunded! I love the colors and the other four trays are in good condition. They’re already in use for pre-sprouting ranunculus corms."

"As an avid gardener, I wanted high-quality products for my plants. I recently tried the Mr. Pen Plastic Growing Trays and I'm very impressed with their durable plastic. They’re a great size for starting seedlings, and I've noticed a significant improvement in my plants' health since using them."

"I need trays without drain holes, and these are just right! I'm pleased with the quality, though I wish they were a bit taller. That's my fault for not checking the sizes correctly!"

"I'm very pleased with this product. The grow lights make seed starting easy, and the price is great! Just a key tip: since it's a terrarium, I only lightly spray the soil to avoid overwatering."

"Living in the cold Pacific Northwest, I was thrilled with how easy the assembly was. I planted tomatoes and cucumbers, and they sprouted in just a few days! The heat mats were a worthwhile investment for my garden."

"I've started several plants using this kit, including moringa trees and acorn squash. The grow lights are fantastic and come with timer settings. The water-catching tray and drainage are great features too. I highly recommend this!"

"I didn't use the germinating trays, but the heating mat is well-made with a great digital display. The illumination turns off in about 10 seconds, which is perfect for my tent setup. Overall, I'm very happy with this product!"

"I wish I had discovered these trays earlier. This spring and summer, I wasted a lot of seeds on peat pots with terrible results. I tried these trays about three weeks ago, and to my delight, all my seeds sprouted and the plants have strong transplants. The moisture control is excellent, and I highly recommend these!"

"I needed starter kits with domes to keep my cat away from seedlings, and these trays are just right. While I find the trays a bit small, I appreciate that they are still reusable and a great deal!"

“I find these trays perfect for a beginner gardener. I use them every spring to plant my flowers, and they work wonderfully!”

“These trays are affordable and do the job. I learned the hard way not to wash them with hot water, as they warp easily.”

“I’ve used these trays several times now. They are not as sturdy as I hoped, but they still function well for starting seedlings.”

"I got these for starting small groups of transplants where I didn't want to tie up a large tray, and they worked well! The trays are sturdier than my previous ones, and the water tray edges provide extra support. I was disappointed to ruin a couple, but I'll definitely order more."

"I recently purchased the MIXC Seed Starter Kit and I'm really impressed with its quality and functionality. The 120 cells are perfect for various seeds, and the humidity dome fosters healthy growth. I highly recommend this product to anyone starting a garden from seeds."

"These trays are easy to assemble and helped my seeds germinate quickly. The quality is excellent, not flimsy plastic, and they seem like they'll last a long time. I'm already planning to buy another set!"

"I found these seed starters to be perfect for my needs. They are sturdy and easy to put together, and the lighting works great for proper growth. Cleanup was a breeze!"

"Initially, I wasn't sure about these trays, but I ended up loving them! They are ideal for beginners and the design makes it easy to manage seedlings. I appreciate the individual cells, which help eliminate worries about germination time."

"These trays have significantly improved my seed starting experience! The clear trays let me monitor root growth, making it simple to know when to transplant. I highly recommend these for their versatility and ease of use."
