Autoflowers under 12/12?

[thizzness]

I've always wondered, how do autos fare under 12/12 light? I'm doing a seedrun with a few himalaya blue diesel plants and they look like they're about finished, but I've also been vegging a couple normal strains and need to put them under 12/12 soon. I could stand to wait until the HBDs are done but would much rather let them finish under 12/12 if it wont hurt them.

On another note, these HBDs fucking reek. Nearly every week I have to add more carbon to my filter or else my room starts to get ultra stanky.

I have read others say that they don't do well under 12/12.

The only difference would be to the amount of bud the plant grows in shorter daylength (from 24 - 20 hours down to 12). So 40-50% of your growth for the days you keep em under 12 hours instead of longer days. If their almost done you wouldn't see much difference, maybe smaller seeds.

I moved 8 snowryders from a 400watt MH on 20/4 to a 600 watt HPS on 12/12, about 2 weeks ago. I wouldn't say they are suffering at all. Will be my best yeild yet from the SR's. I attribute it more to the 600 but there is no lack of bud growth. The one that has been in there the longest has a coke can main cola.

finishing them under 12/12 would be just fine, no problems at all. infact, afaik it should help mature your seeds faster and ripen the buds faster.

yeah arctics right i dropped to 12/12 when my seeds became visible and band they ripened up real fast

So I've had my hps on 24 hrs a day for the first 8 weeks. If I drop it to 12/12 will they amber up sooner?

Most people get the best results with 18/6 growing autos

i had my plants on 18/6 then dropped it to 12/12. they seem to be a lot more stinky.

remember that on autumn equinox which is harvest time many places, that the day is equal in length all over the planet.. its 12/12 on latitude 70 north aswell as on the equator.
