Happy to help, there are some great gardeners here and you can learn a ton from these guys. I speak from my personal experience of 25 years of growing. I mostly have grown indicas or indica crosses, Northern Lights was and remains one of my all time favorites, an "old school" version from 1990 back when she was dominating the contests. I think modern Northern Lights is watered down compared to my strain which I lost a few years ago. Its painful to talk about, that strain was family.
Anyways you have some great resources here, and depending on where you are and what your going to do you'll find someone who can guide you and save you from making mistakes and help you make good decisions to produce excellent bud. There are guys who are masters of the medical grows and guys who are masters of the guerrilla grows.
I'm a huge "fim or top, and bend" believer. If there's one thing I try to teach its the art of bending, just simply gently bending horizontal the top growing shoot which will make another branch try to become dominate and boost growth. This creates big thick shrubs instead of tall wispy plants. Just bending a plant can easily double the amount harvested, and that is being very conservative. Bending,thats my thing!

5 Northern Lights clones started late in June. My buddy took a couple clones grew them his way and he grew just over an ounce each. He blamed it on the late start. I got between 6 to 8 ounces each and blamed it on BENDING! LOL
