Grow rooms can have a variety of grow lights used. Inexpensive LED Grow lights are great way to keep the temperatures down in your smaller grow room or a grow tent. Technology has came along way since they first came out over a decade ago.
Many smaller companies have similar technology and designs. I recommend these inexpensive LED lights in Veg, and as supplemental lighting in Flower. Some growers will flower with these inexpensive LED lights, but I usually hear how their yields have diminished. You can have good yields from expensive LED lights, but they are usually 3 times the price of HID HPS DE lights.
The more expensive LED lights will allow you to control the your light spectrum for desired effects. I have not grown with these lights yet, but the companies selling them say you can dial in your plant’s needs.
