Hi there. I have to tell you - years ago when I grew my 1st crop, I didn't know my head from my ass as far as what to do, what strain I should try, etc. (BTW, I'm a medicinal user). I just made a very LUCKY guess, and ordered pure Afghani seeds, because I pretty well knew that a 100% indica would be better for my physical pain. Long story short, those plants pretty much grew themselves, and I didn't know WHAT the hell I was doing! All the growing information I had I gathered from online posts, which really were very general, & didn't address any problems that might come up. Anyway, the plants grew short (about 1 meter, the average height for the strain), and to this day, that crop remains the best pot I EVER smoked. Very sweet, a strong body stone but my head remained clear, etc. Too bad I didn't have the knowledge or foresight to pollinate & gather some seeds from that particular grow, because I miss it to this day!

Another thing YOU didn't mention is whether you plan to grow indoors or outdoors. Northern Lights is great, but generally an indoor plant, and very delicate. The Afghani and Afghani #1 strains are very sturdy, and don't succumb very easily (unless you have a horrible infestation). Just my 2 cents. Good luck with your grow!
