I want to chime in about hermies and cali connection. i have been growing 818 headband, the exact same clone/cutting, for 2.5 years now. i had bonsai mother 2 years old until i replaced it. this strain hermies WHEN IT IS GROWN IMPROPERLY. that is a fact. if you are light on the nutes and change the rez out every week, and don't harvest after 9.5 weeks or so, YOU WILL NOT GET NANNERS. Even when I got tons of nanners (maybe 10 or more per plant) the harvest would still only produce maybe 4 seeds per pound. the pollen from my nanners seems to not pollinate any other pistils.
so yes, the plants will self seed, but it is due to grower stress and being a beginner.
the product is so potent, last harvest one of the budtenders insisted on taking it into the lab for testing, and it came out 23%. i will grow this exact clone until the day i die.my headband plants get to be 9oz or more indoors in 5 gallon buckets. the strain is a winner, but you must be a good grower. good growers know how much nutrients to give, when to back off, when to change reservoirs out, and when to harvest. i've harvested headband at between 8 weeks and 11 weeks, and my yield at 8 weeks from flip is over 8oz per big plant. a good grower will also give the plants a proper fade, meaning if it's green at the end of harvest, YOU DID SOMETHING WRONG. as a desired grower for local dispensaries, I have learned what is good and what is not. when a grower says "this strain doesn't yellow much at the end" that just screams beginner to me.
