I'm sure some strains are more sensitive to light than others but what I've been growing for the last like 7ish years doesn't seem to really care that much. I went on vacation for a week and left my 60w led household lights on in front of the front door of the tent left open halfway and didn't see any reveg or nanners. The intensity of the light matters a lot, and light loses intensity crazy fast when it's diffused through a opaque bulb and travels more than a foot or two.
Why do people care about pinholes in tents?

I keep my tent in a outdoor shed. Lights are on when it's dark out off when it's day time.
Shed is absolutely not sealed from light. Comes in all over the place. The tent I was using had pinholes of light leaks in multiple different areas.
My plants were fine, no reveg, no nanners, no hermies.

I worry way more about light leaking out of my space than light coming in. I've never had a problem with re-veg or nanners from tiny light leaks, but I don't want nosey neighbors seeing extremely bright light poring out of my window.
My thought process started on this when I picked up this tent.

I love this tent. I've gone through half a dozen tents so far. And this is the first one that the zippers actually felt like there was no problem. They don't grab on the fabric and they don't stick.
But it definitely has pinholes. Oh well. I'm doing vegetables right now so I don't think about cannabis revegetation. But it made me think about people bitching about it because that's the reviews I see.
Exactly that.
You could do the research or I could go track it down for you. The phytochrome hormones that decide whether or not flowering about to happen are sensitive to certain wavelengths of red light. I don't know which particular wavelengths anymore. But you wave the french fry lamp over them and it kicks them an hour or two into nighttime flowering.

if you stand in the tent with everything zipped up, can you read by the light coming in? if it's not strong enough to read regular size print on a page, when held next to your plants, there's very little chance it's going to harm your plants...i will admit that's not a scientific fact, but it has been my personal observation, after a long period of time. i've had enough light leaks to make most of the people who post about pinholes poop on themselves, and never had a reveg or a hermie from it
Right. Can you read by moonlight? Barely. After your night vision kicks in. There's absolutely no reason to have absolute darkness for cannabis.

if your french fry lamp has bulbs that emit at 660 nm, then it would work, otherwise, not so much....
That was a damn fine article. I'm pretty sure that my heat lamps did a range. This was not a time of exact LEDs. This was a heat lamp that did a range of light. Thanks.
It did not address the specific breakdown of the hormones that are present during the daylight which then changed to different hormones during nighttime as they break down. If someone needs that I'll track it down.
Yeah you gotta watch out when you play with the spectrum though, I have a buddy who invested a lot into his lights and he was playing with it for a while and turned his leaves into red leather one harvest.
I definitely think there's merit to playing with the spectrum though so long as you really pay attention to plant response and dial it in slowly.

Emerson effect . You would run 730nm to tell plants “ time to sleep running them about 15 minutes after your grow lights went lights out.
There are some specific 630-660 nm bloom “ boosters “ that can be run also.
Example : G8 bloom booster ALL RED ( which I happen to use with some older rigs not running reds in their layout. )
It puts out an ungodly amount of bloom red ( 630-660nm ) and pic does not do it justice …. still like the damn thing.
This led board … is a far red “ initiator “ and pretty much costs $ 20 fleabay.
The G8 is a Dorm Grow product.

That article is 5 years after I was doing it. I have no idea what the wavelengths the heat lamp kicked out. We didn't have specific nanometers for lights, we had ranges. This was before LED lights and very specific wavelengths.
