I've grown a bag seed from a commercial batch of GG#4....which has all kinds of Chem strains in it...and then this last run was the Chemdozer -which is Chem91 X Planet Purple F2...and it showed both balls in early flower which I picked off....and then everything was cool...until when I was trimming, I noticed 5 or 6 open and dried flowers...I also found one underdeveloped seed. I asked around and people explained the story of the original Chemdog strain and said to be aware that that line tended to show intersex traits....which, now, in my own experience, has also been the case. I'm not complaining about it. The end results were pretty great, overall...just reporting. And there was no stress induced. It was almost an ideal run this time...no bugs, no temp problems...no humidity problems...no fert. problems...no water problems...used a great light....completely blacked out room....hospital-like sterile conditions...Wasn't me. It was the plant. I suppose it could have been the Planet Purple F2 father of this strain, too...but when I asked, people told me it was likely the Chem lineage.
