Hey my first grow , plants have been outside the entire time. Somewhere in mid to late flowering . 2 of my plants are about a week and a half ahead of the rest. But it is going to be raining all week and the temperatures are getting closer and closer to freezing outside . I have 2 Mars hydro sp300 lights for an up coming hydro grow. Should I bring them inside and use the lights instead? Or will that be harmfulness to the plants going from outdoor sunlight their entire life to a grow light?
The light itself wont matter, it's more the amount of light. If you have enough light to maintain the 35w (actual watts) per square foot, you should do fine
