I think they will be fine in the dark cycle of a flower room but just wanted to double check....anybody else running the hurricane super 8 fans in the flower room even in dsrk cycle?

I don’t run the hurricane fan but put duct tape over the blinking lights on my hygrometer sensors. The green as far as I’ve heard is a spectrum you can use to check out the ladies during lights off and not disrupt the sleep cycle. However I would add some tape for piece of mind. Cross T’s dot i’s and all that.

I wouldn't use duct tape since you can see through it. I used Gorilla tape over my temp sensors and the light went right through it. Electrical tape would be better. What I finally did was just pop the little red leds out of my temp monitors. Green isn't as bad as red, but I would still cover it up if it was me.

Nice. I think I’m going to dissect a sensor in the near future and pull out a light. If I can manage. Great idea I’m stealing it. :clap:

Ya I just used a tiny screwdriver and popped em out. Those little red leds were bright as shit in my Therm Pro sensors.

Yeah man. I have a few layers of tape over the light but a tiny bit of light comes through the plastic housing and it always erked me. That shits going down.

All kinds of green LEDs in my room and no issue what so ever. The gavita lights have a small green led that flashes the gavita controller has green writing on the display that is fairly bright and my mini split has a green led. The gavita controller does have a red led that is very small on it also I think it means I hit the automatic temp dimmer at some point and it's randomly on with no issues from that either. Also my dehuey has green display lights that show humidity. Im personally not worried about anything but that small red led on the controller but it's hard to get to ATM (gonna move it after this cycle) but I'm almost at the end of flower and no negative effects from it.

Tinfoil and sticky tape = lightproof and non peeling.

Metal HVAC tape.

If LEDs mess with my sleep, and they do, I def don't want to subject my plants to them!

Renfro · Oct 15, 2020

Green LED is a non issue. I work in my flowering rooms during the dark period ALL the time using a green LED headlamp. It won't mess with your plants.

Green light is not able to be seen by the plants. Also tiny bits of ambient light aren't going to cause your plants to reveg lol.

Sorry I'm going to have to disagree, the problem isn't so much reveg it's some strains are prone to hermie and a small light leak like that might be the catalyst that straight up ruins your crop! They can't "see" green light so you're good with that but anything else needs to be COMPLETELY covered/eliminated.

I have worked in my rooms daily for many, many years, during the dark with green LED headlamps. I haven't had any issues with hermies or reveg. I am literally in my rooms a lot during the dark period with the green led, for extended periods, watering or doing other things like mixing nutes. I have grown whole rooms of weed with no seeds doing this.

Exactly. Green light is fine. All other light needs eliminated during dark period.

I agree with that, I definitely should have added to my comment any light that isn't intentionally green like literally light bulbs sold for greenhouse use during dark periods then you need to cover it.. Ideally block & stop any light of any color/kind from your plants when the dark period hits for optimal results and insurance.

Apologies on my simplistic way of explaining that the plants are unable to use green light for growth.

Speaking of blocking light I'm actually building a wall tomorrow using 2x4s and panda plastic. I've had a spare house door sitting around and weather stripping that I plan to use to lightproof the door. Exciting.

By the way Foil Tape (HVAC TAPE) works a lot better at blocking light than duct tape or "duck tape" or painters tape etc..

I go in my room all the time with my green strips on. And have in my previous rooms as well.

Hey can you link me those green LED strips? I think I will put some in my rooms, that headlamp gets annoying.

Just RGB strips off amazon, these are the ones I use.
