Simple question: Will house bulbs interrupt the dark period?

You screw the pooch in a potoperiod by allowing a NIGHTLIGHT to shine on the OTHER side of the room. For max on photoperiod,total darkness is needed. Now,I do understand that I'm going to get an earfull from 20 or 30 zit pickers that know it all,quoting a bunch of bullshit about the moon the stars, Well,to all my zit picken friends,the moon is a quarter million miles away.What you are seeing is a reflection of light,with no growing properties at all, this reflection is travelling 1 million miles to the moon,just to be reflected off it. This means the light you see at night will not and does not screw you up in nature.A twist cfl in the corner of the room will. Early photophuckups, can cause hermi situations if already in the genetics, and suprize even the most stabile strains still can carry these traits. There is no such thing as totaly stabile genetics.

It's the red wavelengths of light that destroy the flowering hormone, not UV. UV contributes to THC production. If you are flowering a plant, it needs 12 hour of uninterrupted darkness.
Rule of thumb: if you can see it, there's too much light.

Having said that, I heard that people have blue LEDs on at night because cannabis uses it for growth but not to measure day length.

I suspect that the moon is not that big of a problem because it reflects mostly blue light, and very little red...

Any experts on hermies, please advise.... The strain in question was KC Brains strain.... There were 4 plants. 3 of the plants displayed many of the same characteristics for the most part. The plant I suspect to have been the problem plant had more flower growth and a different more pungent smell to it than the others. My question is this, is the differences I noticed a result of a genetic jerkier or a I-fuckedup-hermie? I know it really doesn't matter, the end result is the same, I'm just curious. Thanks

No, it's a matter of phenotypes. 10 seeds from the same plant, when germed and grown, will have different characteristics from their "siblings". If it's a hybrid ( 70% sativa/30% Indica ), you might get plants that favor the Indica and some that favor the Sativa and many possible variations. That is when people choose the best looking pheno to grow as a Mother plant or breed with another good pheno to make a new strain.

I've seen beautiful females, 7 weeks into flower, who had sweet, tight buds, and then one day, oh no, there's a banana growing out of the top of the main cola. Shit happns..........

Light leaks indoors will cause seeding. The reason it is not as critical outdoors is because of the intensity of the sun makes the moons light not matter. We cannot provide enough lumens indoors to trick the plants into thinking they are outside. The sun also provides a red spectrum at sunset which triggers the plants to sleep. Plants will flower with 14 hours of darkness if you put them to sleep with the proper light spectrum.
Also, fem seeds were first made by interrupting the light cycles to stress the plant into hermaphoradism. The hermed plants made seeds and male flowers and were used in breeding projects.
Since we are only giving our plants a few thousand watts during the day cycle they are easy to interrupt with a house bulb during the night cycle.
Grab Ed Rosenthals book that he uses to teach at Oaksterdam. There is a great section about light/dark period in there.

The sun is 92,955,807.3 miles away.
Does that mean that the sun wont have any effect on photo period???

its not an indoor grow, it was just moved inside at 5pm for the dark period and put back outside after sundown

use green light bulbs only you can get them at home depot. They dont bother your plant

Old thread, but similar problem

I fucked up and left the closet light on during one entire 12 hour dark period (led's were off)

32 days since flip and this was the first light leak

Would it do any good to leave them in the dark for 24 hours and re-start the cycle tomorrow? Or is the damage done?

Don't do anything crazy. Just don't do it again, and hope they're fine. It's probably be OK, but there's no guarantee.

Just ride it out and be more careful, probably fine.

Take it easy there's no damage done, it'll be fine, just keep things as they are.

Any light during the dark period is bad to answer your question simply. This includes those "green" lights. IDC what anyone says we ran those in a warehouse grow and the plants hermed until we got rid of them.

outdoor growers will argue about lights not affecting plants but that's way different than indoor cultivation.

well I knew it wasn't good... but it wasn't intentional, and apparently there is nothing to be done after the fact

hope for the best, learn from mistakes, and keep on keeping on

no, not correct. the color spectrum is what the plant sees and pretty much any color other that green will cause problems.

According to the professor from Utah (growing YouTube) plants can also detect green light.

Happened to me. Left my green bulb on a couple of evenings after tending my plants accidentally. Very low wattage (party led bulb) harvest I had beans and more beans. Still stoney but a pain in the ass. Reminded me of highschool all over again.

I forgot this bad boy on during my last run for 2 weeks during week 5-7 of flower and revegged my entire crop.

Yeah right.

yep, bags were half seeds half stems with some shake

but I haven't had a shirt with a pinhole burn in a while lol
