Hi does it matter what name brand HPS bulb I use for my grow rm...I’m trying to increase my yield...I’m currently getting a little over an oz in a 3 gallon pot..im trying to get at least 2 ozs per pot..many people has said the eye Hortilux bulb is the best but I have tired the hortilux the xtrasun but I always get the same results...My room temp stay at 78-80 the humidity is around 55 percent my soil is great and I add beneficials to my soil and feeding schedule....

this light is 2200k is this spectrum good for 12/12
Your temp and humidity are good. What other bulb are you considering besides EyeHortilux? How often do you change out the bulb? Also, what strain are you growing? You may want to go into a larger grow pot if you are trying to get a larger yield. "The bigger the roots the bigger the fruits." ... The genetics may also be limiting your yield.
