Lowest thc# that you would plant

What would be the minimum amount of thc that a strain would consider planting?

10% anything under 5% can technically be considered rope.

I'd say 15%....I bought 9 or so different strains and the lowest I had was 12% (Skywalker).

Big bud... I grew skywalker once and it was the most potent highest yielding strain I ever used...And ive grown probably 20 crops over 5 years..I must have gotten some super seeds

No shit? this is gonna be my 2nd grow but 1st real grow cuz i didnt end up finishing the first time. I have 9 different strains...I think i'm gonna throw 2 snow white and 1 PPP fem from Nirvana and 1 ak47 autoflower from lowlife in my system from start to finish to see how the setup goes, THEN i need to choose 2 strains from:

3x Snow White Fem (Nirvana)
4x PPP Fem (Nirvana)
1x Skywalker Fem (Dutch Passion)
1x Passion #1 Fem (Dutch Passion)
1x Blueberry Fem (Dutch Passion)
1x Strawberry Cough Fem (Dutch Passion)
1x Automatic AK47 Fem (Lowlife)
1x G13 Haze Fem (Barney's Farm)
1x Blue Cheese Fem (Big Buddha)
1x Afghan Kush Fem (World of Seeds)
5x Power Skunk (G13 Labs, freebies, non-fem)
5x Thai Super Skunk (G13 Labs, freebies, non-fem)

I'm thinkin about goin with blueberry and strawberry cough for a perpetual grow...so i'll take clones from the mothers and hopefully be able to go with this setup for atleast a handful of harvests. What do u suggest?

Ok, thanks. Im planning on doing about 30 autos outside for some weed to smoke during the summer, and then I think that I will try to do about 7 diff. strains with 5 apiece so around 35 plants. This will be my first grow, and the only reason i want to do so many is that I 1. want a bunch of different kinds of buds and highs and 2. Im going to college next year and if I can get enough bud to last me this year or longer it would be great. Is this plan too hard for me to do as a first time grower?
