No problem and you'll lot's from researching and listening to the experienced growers that you find on Forums like this. I've been growing for nearly 10years now and I'm always learning something new about cannabis cultivation. So length of flowering period can really vary from strain to strain. Indicas and indica dominant hybrids notmally finish flowering anywhere from 7 to 10 weeks, with Sativas and Sativa dominant hybrids are normally 10weeks plus. If a breeder says 8 weeks id normally say up to 10weeks depending on your grow conditions. 8weeks would be if you had prime optimal conditions.
