Lol,no its called light reflecting of thc man,powdery mildew haha,my grow box is coated in black and white and gets rubbed down with isopropyl alcohol once a week,the only thing living in there is the plant and the microbes/fungus I put in the soil,its just very very white and in a few weeks when it is done it will be more so,as its under a LED,there is no heat so its piling on the trichs
.Also I was trying to show the underside of the cannopy as people go on about LEDS not having penetration,well I beg to differ
Lighting is a little tricky on those, looks like PM a little bit. My pics sometimes get that haze to em too.
