Light leaks!

Yes

Yes in flower 12 hours darkness is of paramount importance some strains can go 10 11 hours darkness but no matter what strain it is in my eyes light leaks are a big contributor to Herm's good luck.

 

Time to bust out the duct tape lol

 

Bad genetics cause herms....not light leaks. Your goal should be total darkness but a few pinholes are not going to be an issue. My buddy grows in a room that has a cloth over a window that is not even taped at the edges. Your eyes do not have to even adjust in it. Never a herm and he grows great stuff.
My own room also has some issues in this area. Also never a herm or reveging. Just one of many old wives tales to get newbies to strive for the optimum. So, strive...but without worry.

 

If you grow outdoors, you learn that light leaks and schedules aren't what they are cracked up to be.

However, if you have a veg light right next door and it leaks into the flower tent directly, it CAN herm. Been there, chopped them lol.

Otherwise, indirect or incandescent light is no big deal.

 

Genetics. I grow in a room I built in a barn. In that room I have a clone cabinet that has a velcroed-on door. At first it was pretty solid, light wise but over the years as the velcro has begun to break down there are pinhole leaks around much of its perimeter. Never a problem. My electronics (heater/dehumidifier/speed control) all had lights that I originally black-taped. As the years went by and the tape dried up and fell off...I never replaced. Never a hermie. I don't doubt you had herms but i hightly doubt that light leaks were the main catalyst. The friend I mention above has been growing for 30 years in the setup I mentiion. RM3, also a long-time grower and a genetics master and strain creator will tell you the same thing I did. He used to be on RIU...maybe still is.

 

They were clones of my outdoor plant that didn't hermie that I moved in for the winter. I had an inch of light from my HPS leaking through my fan (didn't think about it). They hermied.

I agree that genetics plays a larger role, much larger than most, in hermies.

So, you don't think stress during flower can cause hermies? Any stress?

 

Not what I said. I don't think a few pinhole leaks in a tent door will cause hermies I think a room whose light leaks have a plant teetering between flower and veg...could add to the stress component perpetuating the herm...sure. That equates to about the same light level a full moon reflects and that's a whole lot of light.

 

I didn't mean it in that context. Context is lost in text, my bad.

I was just thinking about any other stress during that grow that I could have blamed the light leak. Nothing is coming to mind though. It went smooth.

I don't know enough on the botany level to come to my own conclusion, so I just avoid light leaks. Good practice anyway to keep your tent sealed I guess.

Interesting though and I will definitely be checking into it. Thanks for the heads up.

 

Man. It’s crazy. Most ppl say light leaks=hermi. Then other say that’s BS. MIND BLOWING. I THINK IF U HAVE SOME OUTSIDE SEEDS THATS BEEN TRAINED And grown outside IN THE WILD ITD BE FINE. BUT IF YOU HAVE SEEDS BREED IN CAPTIVITY. OVER “generations/each grow that’ has seeds” those seeds get “used to” complete darkness during lights out. After being breed like that for so long I’d assume it gets “imbeddin in its bio” and needs the complete darkness unlike its counter part that grows outside. I don’t think it’s bs light leaks cause hermis. I think it’s all about genetics. If it’s been grown repeatedly with zero light during lights out that’s what it’ll need. If it wasn’t then light leaks won’t be so much of an issue

 

Sounds plausible.

 

So you think a few years in perfect or not so perfect light situations is going to override thousands of years of their biology. Nawww.

 

Why not? Animals have done it, look at spotted moths. Getting picked off by birds because they were all white. Developed spots to camouflage after coal dust settled on them. Or so the story goes.

 

My uncle has had an 88% wolf and a 5?% wolf. While they was both fairly nice the one with less wolf was way nicer. The 88% was a good dog but it was more Temperamental. And yes I think years of selective breeding and changing it to suit ur needs will effect it.

 

I pondered this, last year, when my partner advised that I must have no (ABSOLUTELY NO) light leak when the 'timer is off'.
Well... I considered that.
It's kinda like saying that the corn won't grow because cars with headlights are passing by all night.
Horsefeathers!
Don't be thoughtless, but no need to be compulsive. Eh?

You have moved the goalpost. Nice try.

 

Don’t rly follow. That was just an example. But as I’ve stated b4. For every one person who says light leaks cause hermi or vise versa there will be HOARDS more sayin the opposite! I still think it comes down to genetics and what stress it may or may not have encountered b4 hand. Unfortunately I do not have the room to designate a grow tent for a test. But I’d love to get one and run a 12/12 cycles. Then hang a small cfl in there on another timer comin in every 15min for 1 min during lights out and see if ur accurate. If so. There should be no neg effects from it??!

 

In the original you made no mention of mixing genetics...just that the lighting method used would get "imbedded in the bio". Silly.

 

I don’t think I was talking about mixing genetics to stop hermis. I will go back and read but fairly sure I said. Growing seeding in completely darkeness thru generations of seeds with “imbed” the trait of needing complete darkness. Kinda like some shows and moves where ppl are stuck under ground In the dark for generations for whatever reason and they adapt to be able to see and live in darkness. I’m sure plants do same type of thing. If someone took an outside strain from the 60-70s and bred it inside with complete darkness during lights out to where it nvr hermi Or throw nanners then took it back outside where it was exposed to natural light and cars and shit bet it hermies
