Autos vs Fast Flowering

[BByce79]

Has anyone grown any of these “Fast Flowering” strains? They seem to have the same harvest times as Autos but with a higher yield. It has me wondering if I should try some of these over the Autos I planned on

I am trying a few fast varieties this year. Sweet seeds green poison Fast and Cream Mandarin Fast...looking forward to see how they do!! I ran the green poison regular last year and it was done mid sept.

Interesting thread, I now have to consider throwing in a seed or two of the fast flowering next season! just to compare for myself.

Not quite on topic, but ...
Was recently checking out the UK Real Gorilla Grow vids on YouTube.
Those guys do some amazing big commercial grows, 1000s of plants.
They also have their own strains, bred in the UK.
I see that they do a lot of "semi-auto" strains, or have some auto genetics in them.
I understand that Sweet Seeds' "Fast" lines are the photo and the auto
of the same genetic lines, I guess 50/50%.
Not sure if the Real Gorilla are so tidy, but look interesting.
They breed for UK, so need early finish (and prob mold resistant).
FYI
I also think that Female Seeds' "Easy Sativa" is semi-auto / fast strain.
And then their Outdoor Grapefruit has a little of that in her too.
They are also fast outdoor plants that are high mold resistant.
Some of the Real Gorilla strains seem to come from Female Seeds',
Easy Sativa, Maroc and related strains.
FYI

biggest difference is that early strains react to lighthours while auto's don't, so you can get bigger yield by planting earlier, but you can't finish during the height of summer like you could do with auto's, since they'll only be triggered to flower once daylength reaches a certain tresshold.

btw, early and semi-auto isn't exactly the same. earlyflowering without auto just has an early tresshold, it could even behave like an auto if that tresshold is very close to the daylength at 21 june(the longest day) at your location.
with semi-auto one of the parents is a full auto, apparently this makes the plants flower around 2 weeks earlier, but it's not stable, and can't ever be stabilized: if you inbreed a semi-auto, you'll get segregation again into 25% full auto, 25% full photo, and 50% semi-auto.
while early flowering without auto-gene can be stabilized.
sometimes it gets a little confusing though since earlyflowering strains are sometimes called semi-auto while there's no autoflower gene in it, because males are always a little earlier so in some of those strains you'll observe that the males behave as an autoflower(under outdoor daylength, you should be able to keep them in veg under 24/0, although I've never tried that), while the females behave as really early flowering, and start flowering not long after 21 june, finishing in august-first half of september.

Me doing same fast strains this year, need earlier finishing girls!

I grew three C99x Blueberry fast that finished about 2 weeks earlier than my green crack. Very little bud rot even with the rainy cold September we had.
