Gardening is a hobby that the vast majority of individuals appreciate and enjoy but gardening can face some issues depending on where it is located. Due to the increasing population of people and cost of land in urban areas, spaces for gardening are also getting more difficult to obtain. The main objective of this study is to develop an indoor capable machine that could create an environment for plants as much as outdoor gardening. This was achieved by providing the machine with the features like automatic irrigation, fertigation, and self-adjustment of the temperature inside the machine with the use of a temperature sensor and DC fans. In order to prove the efficiency of the prototype, seven(7) tests were conducted. The first test was the prototype functionality test, as per result of this test the prototype performed all of the scenario in the test successfully. The second test which is the mobile functionality test was conducted to test the mobile application of the prototype, as per result of this test the mobile application was deemed successful since it perform all the scenario in the test. In the third test, which is the effectivity test the prototype successfully make some of the plant grow. The fourth test which is the DHT11consistency test, the sensor that is in the prototype successfully perform its job since it can detect if the temperature is going up which will make the DC fans turn on to maintain the right temperature for the plants in the prototype. The fifth test which is the scheduling test was successful since the prototype perform the expected result for this test. The sixth test, which is the grow light accuracy test, as per result of this test was successful since the grow light works in exact time that was set in the test. The last test, which is the response time of software application to control the prototype test, the result was successful with consistent one (1) second latency in sending command to control the prototype. The prototype is presented to twenty (20) evaluators to determine its performance. The overall performance of the machine is evaluated through 20 evaluators and acquired the rating score of 4.60 which implies the machine being highly acceptable. This concludes that the microcontroller-based cultivation system for plants can provide the right environment for the plants and achieved the designated objective on automatically nurturing the plants indoors.
