Rasoli #2 was unmistakably male when performing bug check this morning with a magnifying glass. WOW. No other plants of 25+ are showing sex characteristics.
I moved it to my isolation tent with stunted seeds on a 24hr light cycle this week. I will probably snip off the flowers, push it back to veg and breed with it. I would like to make lots more Rasoli seeds by inbreeding anyway; and the plan is to keep any males until I am sitting on a pile of seeds like with my first grow out of the ACE Double Thai.
Preserve the genetics THEN fiddle with phenotyping, cross breeding, and smoke quality.
7Apr: at the beginning of week 4, we have two Rasoli's. One has decided it's a boy, which seems early as hell, but I have been on 14hrs which is a little close to diurnal triggers, so maybe my fault that it sexed early (not that its a boy). The fact that the other Rasoli shows no sex at this point hints that its a girl, so I can inbreed them. Fingers crossed. Pics later.
Plants, like animals, express sex differentiation as a fuzzy scale where lots of hormones are released. There are inter-relationships between PGR (growth) and auxins, cytokinins and a whole boatload of O-chem stuff that is largely under-studied. So, the Rasoli may have been 58% boy / 42% girl and then environment factors kicked the hormones into overdrive and it expressed itself male. This is not really 'stress' but instead 'adaptation'. Hybrids are IMO less susceptible to this than true landraces, but that's just my guess.
