In search of cookie sheets and seedling trays

Hey, neighbors! It's that time of year, and I'm getting ready to plant seeds for the spring. I reuse as much as I possibly can, but, at 5-10 years, some of my materials have reached the end of their usefulness, and it's time to get new (or still-got-life-in-em used). I'm looking for 10" x 20": 1. Cell packs of up to 72 cells; 2. Bottom trays WITHOUT HOLES that hold the cell packs. 3. Clear domes to keep seedlings humidified. (If I can't find any of bottom trays, cookie sheets work just as well.) If you have (and are willing to part with) any of these items, please call or text me. 🙂 412-251-9759 Thank you! Rachel
