And how do you know this? Read it? Or have you grown plants for over a year? Real world experience is what I'm talking about... not what I read or heard!! Sorry no pics. Polaroids don't last that long... and getting them developed would have meant Federal prison. This was 1974-84
Ok see though we can call bullshit on you because the burden of proof is on you. You're claiming you had a plant flower under an 18/6 light schedule. No one else has experienced this but you and you expect us to believe you based on what you say and now you're making your story even less believable.
Polaroids DO last that long, I was born at the turn of the 90's and still have Polaroids of myself as a baby. You could easily still have them.
Plus getting them developed wouldn't mean federal prison, self developed Polaroid cameras were avaiblibe at the time and not that expensive. If you had the money to grow weed back then you had money for a Polaroid camera. To top this all off it was more than thirty years ago?
All these facts compound to make your story simply unbelievable and you get all mad at us when we doubt you.
It'd be like me coming on here telling you all that I had a plant that produced four pounds under a single 150W CFL in a 2x2 scrog, but I didn't take any pictures, it was ten years ago, but you just have to believe me because I said so.
No one else has had a plant flower under 18 hours of light, no one else has documented it, so we can only assume you're either A. don't remember correctly or B. lying.
And you also need to clarify what you meant by your plant flowered...did it start making buds OR just shoot out pistils? Was it indoor or outdoor? Is it possible lights were cutting off somehow?
Regardless, I personally think you're just not remembering correctly. As I've said, your unique claim needs some unique evidence, otherwise no one here believes you and you just come across as a petty liar when you get all defensive about it.
Edit: To answer your initial question, I've both read and seen the effects the light cycle has on the plants flowering. I've been growing for close to a year now and have three grows under my belt. My personal experience doesn't change the validity of your statements though, that's just you being immature and trying to push the onus of this debate onto me in an unfair way because it distracts from your claim of flowering a plant under eighteen hours of light. Keep the questions relevant.
