Week 3 included careful monitoring of sprouts in 6" pots, watching for roots to stick out from the bottom. Both the Rasoli plants rooted out well, and were repotted.
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.
