A 4×4 tent or space would be required to cultivate 4 weeds. Thus a mid-wattage light would be ideal for this area in order to produce high-quality buds.
I am not sure whether I can grow them indoors since they are usually big.
Are they worth it? Currently, I have a HPS light.
I want to buy grow lights for my plants. I have learned online that there are red and blue lights and full spectrum lights, what is the difference between the two?
