I was recently told to use a green light if I needed to enter flowering room during lights out, because the green illumination would not affect the photoperiod. Is this correct, and what are the specifics? I am concerned about the little green light on my dehumidifier and the fact that it reflects from the Thermal Shield.

plants process all colors exept green thats why there that color...green light's are precisely what you need.

this is interesting.. I did some research about it, here more info if someone is interested in this

info taken from here > Will green light kill your plants? Exotic Rainforest rare tropical plants

but still I'm not very sure if the plant would not be affected or if it will notice green light
would be nice if u need to light your plants or check them when the lights are off

for the green light coming from the dehumidifier I wouldn't worry to much if it is just an small LED or something, or just put some tape on the top of it

thanx for the responses. i appreciate it.

Some believe that green at 530nm contributes to the 'accessory pigmentation' and that green in that spectrum is beneficial.

Honestly, I don't know what is correct, but I do know I use a 530nm Inova X1 Green Led (You can get these at Beachaudio.com for $8.99 was $7.99 yesterday) for nightime use in the event I must go into the growroom during the night cycle. I've done so even in the transitional time from veg to bloom and never noticed an increase in the transition time from using a 530nm green LED.

So how much weight does this accessory pigmentation add to the discussion of green wavelengths and herbage, I couldn't tell you.

luckily not since I left my green light on in the grow closet over night the other night...if they did my plants would've probably been fucked.

Bamm Bamm, do you have some type of specialty bulbs, or just one of the GE party light type? I got 1 for $2.24 @ Walmart. It's kinda bright, and it looks as if the whole bulb isn't totally covered, maybe a slight crack of light getting past the green.

one of those dark green ones.. My previous landlord left it behind in his previous growroom when I moved in...


No problems I've harvest 18 of my 50 ladies so far with no issues...

You realy should buy a bulb suited for the situation. Only the GE and Walmart knows what spectrum those party bulb produce. If you want an incandescent type of bulb in green, at or near 530nm. They make LED equivalent bulbs that are 530ish in spectrum for night visits to the sleeping plants.

I posted that Inova Green 530nm X1 LED for about $12 shipped. You can rest assured, I looked up the pdf and made sure it was 530nm. It's got this conical optics thing and every grower should have one, its pretty small, about the size of your thumb. Has a sheath, I put velcro on the sheath and mounted the sheath/light on the wall, next to the grow room doorknob, everyone should have a growroom nightime security light stuck on the wall, no?
