indoor starting, need help

Hello, I plan to grow 10 plants in 10m2 to 21m2, 2.8m height but havent`t decided on the seeds yet.
There is going to be a good amount of light, 2 HPS lamps of 600W are enough I think.
What indoor plants with high amount of THC have the biggest yields and are not hard to grow, I am a beginner yet.
Are there some nutrients that I need to use in the vegetative stage?
Thanks a lot, I would really appreciate your help!

I wont be much help on nutrients, I use super soil.

But I can recommend two plants that im on my second grow of.
I got a 5 pack of each and found 4 keepers that I wont be letting go of.
Had 7 of 10 turn out female, out of the 7 all were great but 4 of them were just amazing phenos.
The kind of stuff you cant wait to smoke and impress your friends with.

If you are looking for a sativa dom plant TimeWreck by TGA is a amazing plant.
If you are looking for a indica dom plant Space Dawg by TGA its so fruity smelling just amazing.


Here is a link to the soil I use in case your interested. https://www.rollitup.org/subcools-old-school-organics/338384-2010-revised-super-soil-recipe.html

Edit: to add that both yield great and are very potent.

if this is your first plant i would get something that doesnt cost as much or is easier to grow indica is easier to grow and to trim
