Overhead water the seedlings until the roots are able to reach the bottom of the cells.This will prevent the seedlings from becoming leggy. Keep the light as close to the plants as possible without touching the plants.

If the seedlings are being grown indoors, place the tray(s) under a grow light.

Once the seedlings have emerged, remove the humidity dome.

Keep a close eye on the trays for germinating seeds.

Water once more and place the humidity dome on the trays.

We highly recommend using perlite as this will prevent algal buildup on the surface of the seed starting mix. Place seeds into the indentions and lightly cover with more seed starting mix or perlite.The indention should be twice as deep as the diameter of the seed you're planting.

Make a small indention in the center of each cell.Wet the seed starting mix thoroughly until the entire cell is damp.Be sure to use seed starting mix and not potting mix, as the potting mix is too chunky and will not allow the seedlings to develop a solid root ball. Fill each cell with seed starting mix.The humidity domes create a moist environment to improve seed germination. The bottom watering tray provides a water catchment system and a water reservoir for watering once the seedling roots are able to reach the bottom of the cell.
