1. Light measurement:
Having sufficient light intensity is essential for plants to undergo photosynthesis, and typically, plants require 800 lux to 1500 lux. Customers can easily determine whether the light intensity is sufficient by downloading a light measurement app on their smartphones.

2. Watering interval:
It's difficult to measure the moisture content of soil in traditional planting methods, so novice planters may easily overwater or underwater their plants. However, the new soilless planting technology of Pafcal can solve this problem entirely.

When Pafcal is dry, it exhibits three characteristics:
1. Becomes hard  2.Becomes light brown  3.Occupies a smaller volume

When Pafcal is wet, it exhibits three characteristics:
1. Becomes soft   2. Becomes dark brown  3.Occupies a larger volume by 20%

3. Air circulation:
Having flowing air indoors is necessary for proper ventilation.
