i have had the g13 labs royal kush and my genetic of royal kush are def better, the resin production is insane i have a friend with 1 royal kush plant that is outdoors still and near perfect maturity 1-2 weeks to go. He puts it outside on sunny days and inside on rainy days but he makes sure it get light 12/12 so it is budding fine, also the royal kush is a very high yeilder. My friend had a rather large havest last season, with 5 plants outdoors planted in the ground he cleared 3lbs dry. The thing is usually a strain has either high yeild, or high potency either or, but with this royal kush it has a high yeild and high potency the crystal and resin production is insane. I peronally just have never seen a strain quite like it, I will be posting up a pic of my royal kush harvest and I will get some pics of my buddies plant too when it is harvested. Come to think of it my cousin got 30 seeds from me for $100 last year and he recently told me he too also had a indoor setup but he has a 250w hps with 12 plants all royal kush, I will get a pic of that too when it is done but he is only like 2 weeks into flower now a little behind me.
