Light intensity experiment

experiment content and purpose

It is said that three elements of sunlight, water and fertilizer are necessary to grow plants.
How much difference will be in growth if sunlight is different among them
I was interested before, so I will try to experiment.
The contents of the experiment grow lettuce indoors (LED light) outdoors (sunlight) and compare and verify the difference. (*^▽^*)

Experimental overview

Sunshine comparison experiment
Lettuce lit indoors (LED light) with 14 hours of sunshine hours and 14 hours of outdoor (sunshine) sunshine hours Compare the differences in growth.

What you have prepared

1. Water tank (with LED lighting)
2.lettuce seeds
3.fertilizer water.
4.container (tool for outdoor use)

Sunlight comparison experiment

 

This experiment is a sunshine comparison experiment.

To be precise, I tried to experiment by thinking how much the growth of plants differs depending on the quality of light, (＾◇＾)

First, let's sprout lettuce.

I will raise it by placing it outside (in sunlight) and indoors (in LED light).

(fertilizer water, temperature, sunshine hours were the same.)

 

10 days from now.

The outside is dark green

The room is long but tall.

('ω')

 

 

 

 

It looks like after 20 days.

The difference between indoor and outdoor growth has clearly come out.

 

then

The growth of the room became very slow after the 20th (due to the light for watching tropical fish?)

 

The difference between outdoor and indoor after 30 days.

(/・ω・)/There is such a difference.

The power of sunlight is scary! (｀・ω・´)

 

Experimental results

Outdoor growth → It grew rapidly after 20 days. (Because roots grew up and nourished?)

Growth in the room → Growth started to slow after 20 days.

 

Experimental results from future kitchen garden

We reaffirmed the importance of sunlight.

I will care about sunlight and daylight hours when vegetable growth is getting worse. (＾◇＾)
