AutomaticSlim Posted March 27, 2017 Report Share Posted March 27, 2017 Do you think this will work? i downloaded a picture of a green screen to use on my phone when my grow light is off.In fact is it true or myth that green light doesn't wake your plants?

KRON BOURKE Posted March 27, 2017 Report Share Posted March 27, 2017 There are many freebies like lil green led pocket torches etc. So there must be some truth in there somewhere? Link to comment Share on other sites More sharing options...
steve_o_76 Posted March 28, 2017 Report Share Posted March 28, 2017 Would a dark red light be the same ???? Link to comment Share on other sites More sharing options...
Gazza2001au Posted March 28, 2017 Report Share Posted March 28, 2017 When i use to grow outdoors i was anal about the porch light shinning on the plants but it had little effect through out the night cycle, this was a incandecent light bulb around 60-100watts and around a good 9-11 meters away from the plants enough light to elumen the backyard but not enough to triger the plants into day light hours just think of when its a clear night sky with a full moon it lights up light anything even with my eye sight i can still see clearly Link to comment Share on other sites More sharing options...
Sir PsychoHashy Posted March 28, 2017 Report Share Posted March 28, 2017 Indoors are much more sensitive for some reason, I cover or disable any LED's on electrical equipment even. No to red lights, but green and only green seems to be fine, I've been using a green light for urgent lights off work for years with no issues. Something to do with the plants can't absorb it so it doesn't wake them up? I struggle to understand it as a full moon puts out fairly bright light, but for indoors it is an issue.

I was looking at a USA based LED shop the other day and I noticed on one of the LED's it was manufacturered with a green LED I wonder why? I have also heard about plants not being effected by green lights Link to comment Share on other sites More sharing options...
Frazz Posted March 29, 2017 Report Share Posted March 29, 2017 our plants contain chlorophyll pigment which is green, chlorophyll absorbs blue/purple and red/orange spectrum light onlyso the rest of the light spectrum is reflected making them look greengreen light cannot be absorbed by the plant, so green cant energize/activate the chloroplasts which contain the chlorophyll 1 Link to comment Share on other sites More sharing options...

Of green light however the majority is reflected 1 Link to comment Share on other sites More sharing options...

Of green light however the majority is reflectedperhaps i was gerneralising too much, sorrysome plant photopigments do absorb green light this is true, but chlorophyll is the most common pigment in "green" plants that i grow Edited April 28, 2017 by Frazz 1 Link to comment Share on other sites More sharing options...
