907 skunk your presence would be better than that HPS because of the high amount of heat and stress that it's going to put out not to mention the input on your electricity bill you would be better off if you want to upgrade your light to get a good LED series you won't have to worry about the heat as much and the lights are very intense and set to specific spectrums this allows your plant to pick up the most light that it can and they come in more than one Spectrum so you that you can pick or choose and customize your own to the point where you like it over your plants I use infrared regular red lights and blue and orange but I am using 1600 watt LEDs made by black dog
