I grew a northern lights from royal queen seeds out door and had it in the shadow of a large plant 6' tall with a lot of shade and under fed, over watered so it did not get large but I know people get large plants from that strain too. It has had some of the tightest nugs of any auto I have grown even being in the shade out doors. I like it enough I have a 5 pack I picked up from a friend to grow again. I know this strain is capable of 4+ ounce in the right conditions. The bud structure was very impressive.
