When you flat white :dance:
You can cover the walls , beams, buckets, floor, boxes:dance:
You can clean it and sanitize it:dance:
Mylar get stains on it from misting , dust on it.
Mylar causes a vapor between the space between it an the walls , good for bugs and mold.
If you chasing every % than go with a parabolic reflector,,, adjusted,,,for the heigh of the plants. d:dance:
If you think it has a dead spot in the middle , use white paper and a good light meter,,, lots of luck finding it. :thumbsup:
Snell book of optics is a good place to start.:thumbsup:
To see how good or bad a reflector is just use a photo program and darken the picture to see hot spots and dead spots. box and batwing are good for parking lighting, but not good for a short distance like a grow room.
Watts has the power , so make everyone of the damn things work.
gwm grams/watts/month is the bottom line, OHMS, Ohms, Ohms I feel the power of the pot.
