Been a common misconception that foil is the way to go.
When flat white is the choice of people in the know.
You have to be really careful with what you buy because of so much misinformation and sales gimmicks that just dont hold water.
I cant think of any logical reason a person would want to use anything other than 6500K for lights.
The whole red spectrum thing is hog wash because the 6500K bright daylight mimics the light from the noon day sun.
It has every color spectrum you need and many you dont need.
I have had plants start to bloom under it with no problems what so ever.
This is yet more stuff the plant grow suppliers will sell you to get you to spend more money.
Light sensitive plants dont start blooming because of light color change they bloom due to the amount of light they get.
as in total hours.
Or to be more exact the amount of uninterrupted darkness.
This is why most people never see a jade plant bloom.
Someone turns on a light at night and resets the timer of darkness.
The same for poinsettias too.
It just so happens this takes place in the fall with more red light due to the sun being lower in the horizon filtering out more of the light in the atmosphere.
Now we can move on to reflector shape.
Look up focal point and it will lead you in the right direction.
Like in an amphitheater and its sweet spot.
Using this it will allow you to concentrate that light in any given spot by not wasting it by having energy bouncing in all directions an a square box.
This is why I suggested to remove the reflector it is shading the light from reaching all of the plants in the small box.
