So i currently grow my peppers down in my basement using T8 shoplights with 6500k bulbs, for the most part they grow very well. But obviously in the colder months the room in my basement has been slightly cooler. Somewhere around 55-60 degrees. Again, no where near freezing but i still feel like its stunting the growth of my plants if not at least slowing it. What would you guys suggest for the temperature in the basement?
