For strong, healthy seedlings with robust root systems, trust Park's Seed-Starting Trays and Inserts to give your plants the best start. These versatile trays are ideal for germinating seeds or transitioning young seedlings from seed flats, allowing them to develop more fully before being transplanted into your garden. Designed for both home gardeners (of all levels) and professional growers, they offer an economical and reusable solution for nurturing top-quality plants season after season.

The durable bottom tray serves as a sturdy base for the inserts, providing a reliable way to transport seedlings. It accommodates six 36-cell inserts, eight 48-cell inserts, or twelve 72-cell inserts, giving you flexible options to suit your growing needs. Each black poly-plastic insert features perforated cells for excellent drainage and water absorption, ensuring seedlings receive proper moisture and airflow for vigorous growth. The bottom tray conveniently catches excess water when top watering and also supports bottom watering to maintain consistent hydration. The humidity domes rest loosely on top, helping to retain essential moisture for optimal seedling development.

To customize your seed-starting setup, bottom trays, humidity domes, and inserts are all available in packs of four, allowing you to mix and match as needed. For even better results, pair these trays with Espoma Organic® Seed Starter Mix and the AlgoPlus Fertilizer Collection. Be sure to pre-soak the seed starter mix thoroughly before planting to promote successful germination. Give your seedlings the strong foundation they need to thrive with this reliable seed-starting system.

Poli Glow used on bottom portion of the picture
Just put it on 21 foot RV, was impressed with the shine. Key is to make sure the applicator is moist. I periodically dampen with water. Realizing it wasn't going to revive the stickers. Question is How long it will last? What will it look like after it rains? Pictures attached, bottom portion was done with poli glow on June 7,2026 and I have just under a half of bottle left. Maybe I will update once it rains or how long the shine last.

Wish I Had Used This Sooner – Stop Debating and Just Buy It!
Wish I Had Used This Sooner – Stop Debating and Just Buy It! After a lot of debate, extensive research, and way too many hours spent buffing my RV with other products that never fully delivered the results I was after, I finally tried Poli Glow—and I am extremely happy I did. My only regret is not using it sooner instead of letting other people's opinions talk me out of it. The difference in how my RV looks after applying Poli Glow is genuinely impressive. The high-gloss finish it lays down on the fiberglass is deep, clean, and long-lasting in a way that the other products I tried simply could not match. The application process with the included mitt is straightforward and far less labor-intensive than traditional buffing and polishing methods, which alone makes it worth switching to. The hydrophobic properties mean water beads and rolls off beautifully, and knowing the UV protection is working to shield the fiberglass from the relentless Las Vegas sun gives real peace of mind for long-term appearance and protection. For anyone who has been going back and forth on whether to try Poli Glow or sticking with whatever you've been using—stop debating, stop listening to everyone else's opinion, and just try it. The results speak for themselves and I won't be using anything else on my RV going forward. Highest possible recommendation.

Wow just wow. It works great.
I have a 2017 vengeance and it has had a bit of sun even though it stays in a building when not used. It was getting a bit of fading even though I polish it each year. I wanted to try something and this was what I settled one after looking. Yes it is a bit of work on a 43’ fifth wheel. I ordered 2 kits but after a week of working on it after work we went camping and where next to a week old fifth wheel and he asked what I used to make it look better than his. It has a mirror finish on it now. After 6 months it still looks great and it’s durable and ease of use. What an effective product
