Product Details

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.

Get Started With Confidence

Simple Step-By-Step Guide To Starting Seeds At Home

Step 1

Use a fine-particulate seed starting soil and pre-moisten it before filling the cell trays. Avoid chunky or woody potting blends that may create air pockets next to your planted seeds.

Step 2

Be sure to follow the sowing depth instructions on your seed packet! Some seeds like to be sown deeply, while others prefer being on or barely under the soil.

Step 3

A germination dome helps retain moisture in the soil. You’ll still need to water, but less often. Check regularly to ensure the soil stays evenly damp during germination and plant development.

Step 4

If your seeds prefer warm soil temperatures, use our seedling heat mat to warm the soil. Our grow lights provide ideal lighting for newly germinated plants until it’s time to transplant.

Step 5

Remove the germination dome when your seedlings are about an inch tall to allow for more airflow.

    I love the build quality of all the epic gardening trays, however, the 4-cell trays come with an upgrade that has caused me a lot of issues. The soil cavity only goes to 1/4 inch off the ground, so it's like your pot is on 1/4 inch feet. I'm sure this is great for drainage, but it is horrible for bottom watering. If you have 6-cells and 4-cells in the same trays, your small cells end up muddy while the 4-cells are dry.

    Also, for most flowers/veggies I grow, the roots rarely reach the bottom of the 4 inch deep cells. I don't have the same root issue with the shorter 4-cell trays.

    In all, the 6-cells are great for seed starting and watering. The 4-cells are pretty good for potting up, but keep them in a tray with other similar 4-cell trays.

    My first EG purchase was seed starting supplies. The quality was so exceptional that it gave me the confidence to order seven large raised beds. The quality of those beds and the wonderful customer service gave me the confidence to further order the large A- Frame Trellis support. Next is grow bags! All because of the superior quality of the merchandise.

    I’m enjoying expanding my garden collection and buying things that I can hopefully use for years to come. These are a great addition. They can be expensive but the hope is it’s a one time buy!!
