ok guys and gals first time grower here and i have a ? So i have 3 blueberry fem photos growing under the photntek 600w pro in a 5x5 tent.Now i have look all over the web trying to find videos on some body using this light but all i could find was just photntek vids of the light.So what i am trying to figure out is how close my light should be now it did come with par test and it does show what height it should be at when suing 100% for each stage of the plant so i was wondering if anybody uses this light that can help me out or should i just go by the par sheet
