Reusable 50 Holes Seedling Tray (Set of 3)

Plant 2–3 seeds per cell in the seedling tray to increase the chances of successful germination. If all sprout, just snip off the weaker ones and let the strongest seedling grow. The exact number may also vary depending on the seed size—larger seeds might need more space.

Good drainage in seedling trays is essential—it helps air reach the roots and prevents root rot, especially during those early growth stages. If the tray stays too soggy, it can cause fungal or bacterial infections. Proper drainage also keeps the soil from getting compacted and allows the roots to grow strong and healthy.

Yes, seed trays generally need indirect sunlight to help seeds germinate and grow healthy. Most seeds require at least 4-6 hours of indirect sunlight per day, as light plays a crucial role in photosynthesis, which is essential for the growth of seedlings. However, too much direct sunlight can dry out the soil, so it’s important to place the trays in a location that receives gentle sunlight or use grow lights if you're starting seeds indoors. Keep the trays in a warm area with consistent moisture for the best results.

Clean the trays thoroughly of debris, old growth media, and potential pathogens. Disinfect the trays by soaking them in a solution of white vinegar or hydrogen peroxide for a few hours. Once disinfected, thoroughly rinse the trays with clean water and dry them; they are now ready to use!

Fertilizing seedlings in the seedling tray the right way helps promote strong, healthy growth from the start. Use a balanced liquid fertilizer made for seedlings and dilute it to ¼ or ½ strength, as young plants are sensitive to overfeeding. Fertilize once a week for indoor trays, and a bit more often if using grow lights. Apply using the bottom watering method or gently from the top until the soil is moist. Watch for signs of over-fertilizing, like yellowing leaves or stunted growth—if you notice these, reduce the strength or frequency.
