                                                              Experiment 17

AIM: 

To determine the effects of different light intensities on the growth of microgreens.
.

APPARATUS AND MATERIAL REQUIRED: 

1. 3 trays of microgreen seeds
2. 3 grow lights of different intensities
3. A timer
4. A ruler  

Microgreens grown under low light intensity will be short and spindly

OBJECTIVES:

1. To determine the optimal light intensity for growing microgreens.
2. To compare the growth of microgreens under different light intensities.

PROCEDURE:

1. Sow the microgreen seeds in each tray.
2. Place each tray under a different light intensity.
3. Set the timer to turn on the lights for 12 hours each day.
4. Observe the growth of the microgreens over 7 days.
5. Measure the height of the microgreens at the end of the 7 days.

RESULTS:

The microgreens that were grown under the highest light intensity were the tallest. The microgreens that were grown under the lowest light intensity were the shortest. The microgreens that were grown under the medium light intensity were in between the tallest and shortest microgreens.

CONCLUSION:

The results of this experiment show that the optimal light intensity for growing microgreens is medium. Microgreens that are grown under too much light will become tall and spindly, while microgreens that are grown under too little light will become short and stunted.

ADDITIONAL INFORMATION:

1. The type of microgreen seed can also affect the growth of microgreens. Some microgreen seeds are more tolerant of high light intensities than others.
2. The temperature and humidity of the growing environment can also affect the growth of microgreens. Microgreens prefer warm and humid conditions.
3. Microgreens can be harvested when they are 1-2 inches tall.

Microgreens grown under high light intensity will be tall and leggy
