I would guess it's 50:50. Anyway the point is that green filters remove light as they pass through. They don't remove other colors. | |

There's no right or wrong to this if you don't actually know the exact color of the specific greenhouse material you're talking about (which you can't know just by looking at it, unless you've got some serious skills). (They really ought to advertise which wavelengths greenhouse materials block.) Shine some single-wavelength LEDs through it and see what it blocks. The answer could be vastly different depending on what kind of 'green' the material of any particular green greenhouse is (they're not all exactly the same). | |

Plastic blue-blocking sunglasses, for instance, are not blue. They are amber. They do not block amber light, but they allow it to pass through. They look the same color on both sides, too. | |
| Sep 25, 2015 at 19:53 | comment | added | stormy | Your first sentence is saying that a green colored plastic ALLOWS MORE GREEN SPECTRUM to pass through. Then you say green leaves reflect green light. Yes, blue light is great at the beginning of plant growth and switching to red light is great to encourage blooming. Is this a part of lumens? The amount of total light? | |
