Flowering from seed or Autoflowering plant?

Hi,
i would like to have a suggestion from you.

It is better to plant a normal seed then wait 10 days and switch to 12/12
or plant an autoflowering seed with 20/4. I have 90 days!

10 days?? You trying to flower a tiny seedling??
Maybe you should do some research. Please

I did some research:

So you are saying autoflowering plants are better, right?

He's saying to allow for more then 10 days of Veg if you are looking to gauge the difference in the two; or at least be able to yield anything (within your 90 days)
You have 90 days; so i suggest you get a "DNA 60 day wonder auto flowering plant"' otherwise you will not be 100% ready within that time frame.

Thank you very much.
Could you suggest me other 2/3 autoflowering plants? Unfortunately i haven't a big choice of seeds

Are you going to be gone after 90 days? Or can you only grow during that period? They'll dry then cure for quite a while after they are chopped down.

The Easy Rider (about 70 days); allowing for some Hang Time for Drying; curing.
(Find that Strain @ the Board Seedbank sponsor)

Here are some threads where they go straight to flower from seed. Hope this is helpful.

Thank you for your research!
I can only grow during these 90 days but I have a solution for dry and cure.
Btw I started some autoflowers( 6 AK, 3 Speed Devil, 6White Dwarf) 8 days ago... and 14/15 sprouted.
