Starting the Investigation

What are we trying to show with this investigation? That plants need inputs to grow.

To set up this investigation and get us comfortable with growing plants we are going to start our first microgreens.

You will need:

  • 4 – 5×5 microgreen trays
  • Coco coir (from the block you re-hydrated)
  • 1020 Tray
  • 1020 Humidity Dome
  • 2 – 5×5 Humidity Domes
  • 1/2 teaspoon radish seeds
  • Spray bottle

Now let’s get started

  1. Place the 5×5 tray inside the solid bottom 1020 tray. Fill the 5 x 5 tray with 1 inch of coco coir. The tray is 2.5 inches tall.
  2. Use an empty 5×5 tray to press the surface of the coco coir flat.
  3. Spray the coco coir to moisten it. Be careful, don’t add too much water. If puddles are forming, you’ve added too much.
  4. Scatter 1/2 teaspoon (7.5 grams) of radish seeds in the trays.
  5. Spray the seeds with water. Place an empty 5×5 on top of the seeds to keep them covered for two days, then take it off. Germination is often improved by putting a weight in the empty 5×5. Keep the coco coir evenly moist while the seeds germinate by placing the 1020 humidity dome over the 5×5 microgreen trays.
  6. On day 3 when you unstack the trays, place the 5×5 humidity domes on top with the vents closed for another day or two to give your plants the best chance of survival. The vents can then be opened or removed depending on how hot and humid your growing area is.
  7. Leave your trays on your desk. This experiment will have the grow lights off for the first two days. On day 3 when you unstack you will turn on the grow light above the humidity domes.Check everyday to make sure the seeds and media are moist. Give them a couple of sprays of water if needed.
