Can sombody tell me how far my lights should be above my babies? I have 4-85w(actual) 6500k cfls and my plants are auto seedlings.Sent from my SCH-S738C using Grasscity Forum mobile app
the cooler you keep your bulbs the closer you can get them. I used to have blades growing in between the spirals because I had a lot of airflow directly on the bulbs. That being said I'd go no higher than 6" above the canopy.
