A couple of years ago I grew a bag seed, had no idea what it was. Turned out it was a male and I crossed it with Gelato and called it DG (Droopy Gelato). Next year grew DG seeds and one female and one male showed deep red stems. Cloned and crossed these to create DGR (Droopy Gelato Red). This year am making more seeds from the DGR boys and girls
Am mentioning this because the only strain the DGR plants look like is Congo Red Stem. Of course I have no idea what the actual genetics were in the original male (I named him Mr Droopy). The DGR plants I’m working with now have more of a sativa form, deep red almost burgundy stems, smaller flowers/buds and they take about 5-6 months to mature.
Here’s a recent photo of the top of a DGR girl.
