The statement above lead me to believe you have not grown Photoperiod plants. I can do some autos in as little as 60 days, I have yet to grow a Photoperiod plant in less than 110 days most take longer. That is way more than a "tad bit longer".
One thing you need to remember is that seed vendors for Photoperiod plants are quoting "Flowering Time" only. This does not take into account the 30 or so days it takes to get through veg.
Think about it if it was only a tad bit longer Autoflowering plants may not have become popular?
