I have a 400 watt metal halide setup but have two different bulbs. Before when I used the bulb with a more pronounced blue color it would stretch the plants probably due to the fertz at the time. I bought a bulb at a Home Depot that has a more white light. I was just wondering which bulb would be better at giving me a little more stretch between nodes. Right now with the blue bulb its getting very thick stems and staying very short and compacted with the Advanced Nutes I recently started using. By the looks of it the white light should give me some stretching being 4000k where the blue is 5500k and the HPS is 2200k? Does this seem correct? Just want to make sure before switch I guess?
