There are so many strains out there and like IDS said, it depends on what high you're seeking, what size, how long to grow and so on.
I usually pick my strains from quality and high perspective. I personally rather grow a comparably lower yield strain but a real kick in the nuts
Here some strain I like.
Think Differently. Oh man, what I would give to make her my next grow. She's definetily on my top list.
Sativa high, uplifting and creative. Can yield up to 300 grams (Pretty amazing autoflower)
The famous White Widow. If grown properly, this hot product really gets you by the balls. Amazing high.
Mostly Indica will get you stoned, most probably couch locked. Many people LOVE this strain for treating insomnia (Sleeping Problems)
Northen Lights, a very popular strain, many people's recommended 1st time smoking strain. Popular in Amsterdam
Indica strain, euphoric and relaxing, really cool one.
There are over 500 strains, find your type of high, grow and share!
Good Luck with your future grow!
