I love NL - its fucking gorgeous smoke if done well! One of my top 3 for sure.
And growing it, as long its from decent seedhouse, its usually stable, sturdy, pretty resiliant & quite low odour too.
But yeah, don't believe everything u read: including the back of seed packets! If u can pull in 500g/m2 on ur first grow, then u shouldn't be asking questions on here, u should be answering them! lol!
Just do it though & see what u get - even if its 1 spliffs worth, i can guarantee u'll still love it! And then the quest begins to increase it next time, and next time, and next time!
