Is photoperiod bullshit?

My buddy bought a couple clones and is growing them out. He is skeptical that you have to keep a 12-hour period of darkness and avoid light leaks during flower. I will forward your responses to him. Am I full of shit or are these things fairly important?

Thank you, but he is also skeptical that you need to prevent light leaks and keep the plant in darkness the entire time. Is that my bullshit or is that a fundamental principle of marijuana growing?

I have lightoeaks all over but none are enough to make the plant think its daytime - a shit load of light will stress your 12/12 plants but small lightleaks make zero difference and its still pretty dark inside.

Someone trolled that lightleaks cause herms and now everyone believes it but rrally its just troll bait and your gonna get a lot of stuff that in the end was factually very wrong :-)

Not sure what your point is with this post? Yes the moon REFLECTS some of the suns light and can be rather bright when its near full. However it doesn't provide useable light for photosynthesis from anything I've ever seen or read. Thus why plants still flower outdoors even with moon light, and why plants in parks still flower inspite of distant street lights. If you get those street lights too close though they will mess up your plants. Thankfully the moon doesn't stay full or move any closer so we don't have to worry about it.

Much of the growing process has been standardized right here on this site for your convenience. I'm doing my first grow now, and I joined RIU 10 years ago. The more time your friend spends doing research, the more likely he'll be a successful grower right away. I've seen a lot of people jump in head first without doing research, and they end up quitting because their first grow was a disaster and waste of time. The best thing you can do is teach your friend to fish by giving him this website, or telling him to watch grow videos on YouTube.
