In general, plants use wavelengths of 400 and 700 nanometers for photosynthesis, and usually, the sun provides it all and the plants take what they need. Since Urban Oasis is growing indoors, the company must provide a habitat that is as close to plants' natural habitat as it gets. So the right intensity and wavelength of light are very important.
The cool light (430-450nm) is most important for strong root growth, while the red light (640-680nm) encourages stem growth, flowering, and fruit production. Of course, the intensity and duration of light are important aspects to consider when beginning your journey to DIY farming. Depending on the plant you choose to cultivate, you should begin by doing your research.
Usually, indoor plants that are under artificial light need to make use of at least 12 hours of light and the lamp should be relatively close! In this case, the more the merrier method does not work though, because as each and every one of us, plants need some rest. Maybe not for the same reason as us humans, but to trigger the flowering response.
So if you want to dip your little toe into the pool of farming on your own in your home the first thing you should consider is light. What do you want to grow? How many hours of light does the crop need? What should the intensity be?
