Fast 20 sec. green light during dark cycle...

[Olive Drab Green]

I used to keep my first grow in a closet with a curtain over it, and the curtain still came up over the bottom of the meristem and a few leaf tips. Guess who was on the other side, watching TV with a light on without causing his plant any problems?

I have been using green lights in my ceiling lights, in my room for years, and even forgot them on for days, because I rarely go in to my room when the lights are off, They never once hurt my ladies, but I will keep that in mind that they may. But I would add I have never had a problem using the green lights and actually forgetting them on for days. lol I dunno...

I so needed to see this

Something to the equivalent to a lightning storm going by is all right. Light leaks of duration can hermie a plant.

I set up a closet grow for a friend. It had a sliding door that did not fully close, and left a tiny slit. The room had no closed door so his cats used the litter box in there. So light came in from the kitchen. I told him he needed to fix the closet door, or cover it some how. He never did. The one plant closest to the light leak slit hermied.

lol I just use my phones flashlight when I work on my plants at night, although not very often. Never had an issue with reveg or hermies.

I made this exact point before, plus moonlight. Moonlight is not moonlight, it's reflected sunlight.

Also genetics may play a roll?

 

[Olive Drab Green]

Also genetics may play a roll?

I would probably concur with that, yeah.

 

[RM3]

It's ALL genetics, Light leaks do not cause hermies !!!!

I have grown in my basement for years, it is wide open there are no rooms or tents, there is a divider between the veg & flower areas like one of those things folks get dressed behind on TV. When the flower lights go out the basement walls glow from the veg light. The basement door is never closed, at the top of the steps is a window facing west, the glow from actual sunlight makes a big square on the basement floor mere feet from the flowering plants. Between this sunlight and the veg light I can see and do things in my basement and in the last 5 years I've only had 3 plants hermie, if it was true that light leaks cause hermies I would've had a lot more

Lightleak your bloom then.

I have lightleaks without problems, man. Of greater concern are heat and genetics regarding hermaphrodite plants.

 

[THE KONASSURE]

random light leaks are cool, and using a light for 5 to 15 mins won`t hurt anything

but a timed light leak in the veg night that also happens during flower, that can cause issues even with some very stable plants

When you do gas light veg you have to be careful not to have any light leaks during the night cycle as the plants hermi or shock seed normally, price you pay for being able to use 5 to 8 hours less light in veg I guess

 

[bravedave]

I do. Every grow.

 

[Phytium hater]

Every grow I have had some problems with my timers...NOW FINALLY I learned my lesson..the cheap ass digi timers can't handle the HPS power surge ...and finally I bought proper high end Switch boxes with timers...and aaaah no more..what the fuck lights are on during the dark period...

Although cheap ass timers can handle the hps the problem is the inductive load when first turning on that spikes it. Some cheap ass timers write their inductive load on the back of the timer. More quality timers can handle a bigger inductive load. Check the lights and timers for these details to find better matches.

...like I said done deal ..got the best on the market for my usage 2 x Davin DV12 , each can plug 2 x 600w lights in them so I can spread the source plug from different rooms...because there is too much of tech stuff, what needs to get power...

Once again nonsense, I've been doin gas light veg for years as well in the very same wide open set up

The green light idea as "invisible to plants" has been shown false by NASA ( i think).


By now we know that we can grow plants even only with pure green light ...

(..)Transcend takes the input of academia and its customers in crafting products with SPDs for specific applications. “Many companies build horticultural lights with just the blue/far red spectrum because of the hypothesis that these are the only wavelengths used for photosynthesis,” said DeMilo. “Although this hypothesis had some great logic, that chlorophyll A and B absorb these wavelengths more strongly, it turns out that plant growth is far more complicated than this. Some of our customers have grown fantastic plants using 100% green light during testing. This makes sense as plants evolved for billions of years under sunlight. Many recent studies have shown that full-spectrum lighting with properly balanced ratios of wavelengths, say red to far red or red to blue, supports the most efficient plant growth.” (..)

Thats really cool. I also bet that the light doesn't travel as far. Like a red flash light for night walks.
