What size photo plants are you shooting for? That's going to be the key to when you crack seeds and how long they'll have to veg' give or take a couple-few weeks... FV's will trigger early, Sati'-dom's latest and as always the odd pheno' factor is in play too...
Sounds like 25's is a good middle ground for you? May starts, and maybe do a single transplanting from 10-15's to 25's, to give some root squeeze and trick them into slowing a bit.
This is my world here

- razors edge on pot size/plant size/ nute reserves in-soil!
A nice thing about smaller plants and greater variety, depending on your line-up, is having girls finish up in stages to stagger the harvest load and hassle....

holy crap, they got
skint!
Have you tried this before? It looks interesting! ...might have to try it myself....
This sort of cross was made to work in shorter season climates mainly.
Another example: Female Seeds was doing this sort of breeding to speed up Sati-dom' crosses waaaay before "auto's" were a thing. Their C99 is a perfect example of this. That cultivar was hot shizzle back in the day, and northern clime growers had shizzle chances of finishing her in time.
For Asian Haze, there's as wild of a clash of long and short(-er) season parents in her, hence the capacity to get large and stretchy (OTHaze, Meao Thai), but no 14+ weeks of blooming and late triggering thanks to the auto (his Hazes) and semi-auto (the other Thai).
No doubt about it, the auto genetics is actually pretty strongly influencing this F1 cross for sure!

oh man, that's damn impressive GH! What really shocked me was the low myrcene and super high geraniol content. This is very unusual for an NL so far as I've seen....
How did her aroma settle after cure? That lab report hints at floral, hoppy/earthy, woods leaning aroma profile...
And how's the high? This chemistry says pretty Sativa-feeling for what's usually a more body heavy Indica high....

Noted on who's NL this is... So many variants out there!
View attachment 1587586 ... will you be running the custom cross auto/photo's too?
Spring is late-late alright-

...but they seem to be rolling just fine with it!
No rush on choices for the Comp', Jean... I'm stoked you're running the custom crosses along with yours! I hope Mason is too, coz it'll be my vicarious grow of them since I can't run them this season, dammit!
Sounds like Speed' is carrying strong Lilac Diesel expression, which is very nice indeed-
