Buying Guide – What to Consider Before Buying Best Seed Starting Trays
1. Tray Size and Cell Count:
Are you starting a few herbs or an entire vegetable garden? Go for higher cell counts if you’re planting variety or volume. Smaller trays are easier to manage and store if you’re limited on space.
2. Material Quality:
Look for durable plastic if you plan on reusing trays for multiple seasons. Biodegradable trays are great if you’re going green but may break down faster.
3. Humidity Domes:
Domes create a greenhouse-like effect and help control moisture and temperature during the germination phase. They’re a huge plus, especially if you’re in a drier climate.
4. Ease of Transplanting:
If transplanting causes stress on your seedlings, go for trays or pots that are either deep (like the Burpee tray) or biodegradable (like Back to the Roots), which can go directly in the soil.
5. Drainage:
Good drainage is key. Trays that come with base trays or drainage holes will help prevent mold and overwatering.
6. Reusability & Clean-Up:
Dishwasher-safe trays or those easy to clean by hand are much more convenient long-term. Always consider how many seasons you want to get out of the tray.
FAQs
Do I really need a seed starting tray, or can I use containers from home?
You can use containers like egg cartons or yogurt cups, but seed trays are designed to optimize germination with better drainage, humidity control, and root space.
How long should I keep seedlings in a tray before transplanting?
Most seedlings are ready to transplant once they develop two to three sets of true leaves. This can take 3–6 weeks depending on the plant.
Can I reuse seed starting trays?
Yes, many trays—especially plastic or silicone models—can be reused for several seasons if cleaned properly between uses to prevent mold or disease.
What’s the best location to place seed trays indoors?
Near a sunny window is ideal, but if you lack sunlight, a grow light will do wonders. Consistent warmth and light are key to successful germination.
