Lighting Needs Depend on the Type of Plant
October 14, 2018
Ultimately, the type of grow lamp lighting you will need depends on the types of plants you are growing (leafy, flowering, or fruiting), the number of plants you will be growing, the size of the plants, and the dimensions of your growing space. The more plants you intend to grow, especially if they are larger plants, the more grow lights you'll need (or more powerful HID grow lamps) to grow them successfully. Individual plants can often be growing using just one small LED or CFL.
Don’t base your lighting decision solely on the number of electrical watts the lamp needs. Watts are an input requirement of the lamp, not an output of resources for your plant.
