When I finalised my results and observations, I found that there were different trends and patterns happening in the growth of the plants. 

The window plants showed a regular pattern, growing from 0.1cm per day. 

The cupboard plants had a irregular pattern that started from 0cm to 9.6cm, in ten days. I found that the cupboard plants grew the quickest and only grew rapid on some days. The outdoor plants had the same pattern as the window sill plants, growing at 0.1cm per day. I also found that the outdoor plants grew the slowest out of the three environments. 

The graph and table I have created showed that the cupboard plants grew the quickest, and the plants from the outdoor environment grew the slowest. But I have discovered that this did not match my findings from the research information. My secondary data (internet and books) explains that the plants exposed to sunlight will grow the quickest and the healthiest, however my results have shown that the cupboard plants grow the quickest. 

The results and the background information does not match because, the type of seed I used to conduct my experiment was said to grow best in the dark. I have considered and found this statement is both true and false, because the packet says that the seeds grow best in the dark; but I have also found that the plants are not in a healthy condition. 

Although the outdoor plants have grown very little, I found that they could not adapt to the heat and sunlight. I know this because, when I was observing the plants, the soil looked very dry and the soil was not moist. 

Plants on the window sill grow not too fast and also do not grow too slow either. From looking at the results, it shows that my observations about the window sill plants have remained positive throughout my experiment. They had no sign of dry soil or too much water, and the plants have been growing healthy and green.

To make my experiment more reliable and accurate, I placed three plants for each environment. The three plants have been growing at the same height, meaning that  the reliability of the experiment is more precise. 

During my experiment; I have added 10ml of water to each plant, allowing the plants to have a higher percentage in achieving the best results. 

Improvements I could have made would be, to apply more water to the plants. I think the outdoor plants could have received more water because they were lacking moisture and the soil remained too dry to grow. If I had applied more water, the experiment could have been even more successful and also more reliable. 

Another improvement I could have made would be the location of the outdoor plant. The location I have placed the plants had very little shelter. This meant that if rain was applied to the plants, the experiment would definitely be unreliable and inaccurate, because those plants would receive more water than the cupboard and window sill plants. 

In my conclusion, I believe that the outdoor plants grew the slowest and the cupboard plants grew the quickest. Although the cupboard plants grew the quickest, it had no signs of healthiness and looked weak. The outdoor plants had very little growth due to sunlight adaption and lack of water. 

Plants on the window sill grew not too fast but not too slow. They were the healthiest plants, that grew with green leaves and a tall stem. The window sill plants would be the best to grow plants, if the best results are wanted.
