RooTrimmer Humidity Dome, Plastic Clear Seed Starter Dome 1020 Tray Covers Humidifying and Insulating for Greenhouse Germination and Garden Growing (21.5"×11.5", 3.15" Height, 10-Pack)

I really enjoyed the quality and fast shipping. It is rigid enough to hold a full tray of seedlings as I walk through the greenhouse and not feel like it will not break. Its lightweight, fits my standard 50 cell count tray and does a great job of maintaining the moisture and water levels needed. The ridges built into the tray are great and are extremely useful.

great for my long trays, thank you

I bought these 200 cell plant containers sort of skeptically based on having small grow holes. I couldn't have been more wrong. The zinnias grew incredibly well, and can maximize space by using these over 72 cell containers. Great value! Sturdy material compared with other trays, so they are very functional for a wide variety of plants. Standard black color is good, especially for cold weather growing, keeps those roots a little warmer. Cleaning is easy, and as mentioned previously, the thickness was much better than expected. I am fan, I will be buying more in the future, and already cannot wait for the next growing season (its only June).

Awesome seed starting trays. Thick, durable and will be used for many many years. It’s not the cheap flimsy ones from your local box stores, these are heavy duty. I like to use these trays at the start of planting season for a few reasons: 1. Small enough plug size so you can test out your seeds and get them to germinate without wasting a bunch of soil. 2. Fitting 200 starter plants one one tray saves so much space under the lights. 3. Easy to pop out of the tray to either replant in a bigger plug or toss out if it didn’t grow properly. Highly recommended for any green thumb.

How can such a simple thing go wrong. They didn't. Work fine.
