How to choose the best seed starting trays
Selecting the right seed starting tray depends on your plants, space, and gardening style. The core function is to provide a supportive environment for germination and early growth before transplanting seedlings outdoors. Consider how many plants you’re starting and how much room their roots will need; larger vegetables often benefit from deeper cells.
What to look for
- Cell Size and Count: Match the cell depth and width to your plants’ needs. Extra-large cells suit tomatoes and peppers, while many small cells are efficient for herbs or flowers.
- Material and Durability: Trays are made from flexible silicone, rigid plastic, or biodegradable paper. Silicone and plastic trays are reusable, while paper pots can be planted directly.
- Watering and Humidity Systems: Look for features like drainage holes, watering trays, and adjustable humidity domes to help manage moisture, a common factor in seed starting mistakes.
- Transplanting Method: Flexible cells that pop out or pots that biodegrade in soil are designed to minimize root disturbance during transplant.
Finally, think about accessories. A basic tray works if you have a bright window, but a kit with a dome creates a humid microclimate, and one with a grow light ensures consistent illumination. For more on the fundamentals, see our guide on how to start seeds indoors.
FAQ
When should I start seeds indoors?
Timing depends on the plant and your local climate. Many seed packets provide guidance. Generally, you start seeds indoors weeks before your area’s average last frost date to give seedlings a long enough growing period. You can find your frost dates using resources like the USDA Plant Hardiness Zone Map.
Do I need a humidity dome for seed starting?
A humidity dome is not strictly necessary, but it can be very helpful. It helps retain soil moisture during the critical germination period, meaning you may not need to water as frequently. Many trays, like the MIXC and Patigrow kits, include domes with vents so you can control humidity levels as seedlings grow.
Can I reuse plastic seed starting trays?
Yes, most plastic and silicone seed trays are designed to be reusable. The listings for the Burpee and MIXC trays specifically mention they are easy to clean and store for the next season. Be sure to wash them thoroughly with a mild disinfectant to prevent the spread of disease between plantings.
What’s the advantage of biodegradable pots?
The main advantage of biodegradable pots, like the DANALLAN paper pots, is that you plant the entire pot in the ground. This means you don’t have to remove the seedling, which minimizes root disturbance and can reduce transplant shock. The pot will break down naturally in the soil over time.
