About Epic 4-Cell Seed Starting Trays

The Epic 4-Cell Seed Starting Tray is built tough with just the right amount of flexibility. It’s designed by real gardeners and made in the USA from high-strength recycled plastic that’s UV-treated and BPA-free. Each cell features air pruning slots to stop root circling and encourage strong, healthy root systems. The open-bottom design adds additional airflow from below, giving your plants the best shot at thriving from the start.

Choose between 3” or 4” depths to best suit what you’re growing. These trays fit perfectly inside the Epic Universal Bottom Tray allowing you to easily manage your seedlings as a full set or lift out a single unit. When it’s time to transplant, built-in finger holes make removal easy. Just push and place.

The 4-Cell is ideal for crops that need more root space, like melons, cucumbers, and tomatoes. When paired with the Epic 6-Cell, it’s also great for potting up. The Epic 4-Cell Seed Starting Tray is strong, smart, and built to last season after season.

How to Use

How To Use Epic Cell Trays

  1. Fill your Epic Cells with a seed-starting mix, add just enough water to moisten the soil, but don’t waterlog it.
  2. If your seeds are meant to be surface-sown, press them against the pre-dampened soil but leave them uncovered; some seeds need light to germinate. If they have a planting depth indicated on the packet, use a pencil, chopstick, or your fingertip to make an indentation to the correct depth and drop in the seed.
  3. Add a light misting of water from a spray bottle or just enough to moisten the seeds, then cover them with soil and lightly press down to ensure no air holes remain around the seed.
  4. If you have plastic wrap handy, loosely drape it over the top of the pot to promote high humidity conditions (seeds love this), or use a specialized dome cover.
  5. Place your cells on a sunny windowsill or under a grow light, and keep the soil moist as the seeds begin to germinate. Once sprouts appear, remove the plastic wrap or dome cover.
  6. Keep the healthiest seedling and remove extras with a pair of scissors, being careful not to damage the healthy seedling.
  7. Continue to keep the soil moist as your plant grows. When it’s mature enough, easily pop out your starts and transplant them into larger pots or the garden.

Cleaning Your Epic Cell Trays

We recommend hand-washing with hot, soapy water as the best way to keep the material in good shape for years of use. A good dish detergent should sterilize the trays enough to protect seedlings.

FAQ

Q: How long do Epic Seed Starting Trays last?

A: Epic Trays are rigid, yet flexible. They’re practically unbreakable and should last you a lifetime.

Q: Will the soil fall out of the tray?

A: As long as your mix is formulated properly, it won’t fall out. Each individual cell in our Epic Trays features an air-pruning side slot on all four corners to discourage root circling and encourage better root growth. The bottoms of each cell are also open, providing air pruning at the lower end of each cell.

Q: When should I transplant my seedlings?

A: Transplant your seedlings when they are 3 to 4 inches tall. To remove your plants, simply push the seedling out with your finger, then transplant them into your garden or a larger pot.

    Great trays

    If you want a seed starting tray that will last for years, these Epic ones are for you. They are super sturdy and well-made. I would give 4.5 stars if I could. They lose .5 because the hole in the bottom is a bit big, and I suspect that the plants will be harder to remove since you can’t squeeze the sides. Otherwise they are great!

    Hey Tracy,

    Thank you so much for taking the time to share your honest experience with the Epic 4-Cell Seed Starting Trays! I really appreciate your detailed feedback about both the strengths and areas for improvement.

    It's fantastic to hear that you're finding them super sturdy and built to last for years - that durability is exactly what we were aiming for! Your point about the drainage hole size is really valuable feedback, and I can see how that might affect the transplanting experience compared to flexible-sided containers.

    EPIC DOME FAILURE

    Would have been a great creation if not for the shortsightedness of making the width just a bit too wide, causing standard humidity domes to work on a standard tray. Major let down in seed starting!

    great for starting seeds and transplants

    I love these 4-cell seed starting trays. They are very sturdy and deep. I have used them for transplanting seedlings from smaller cells and they work great for that and I have also used them for starting tomatoes. The tomatoes can stay in them until I plant them in the garden. I also like how they stack together for storage. Highly recommend them.

    These are epic! They are very sturdy and last a long time. I have had my original 6 cells for a few years and they show zero signs of wear. Excited about the 4 cells. I am growing peppers, tomatoes, and larger flower varieties in them until it is time to transplant into the garden.
