I just finished my white widow grow, simply the best Ive ever had, although I'm exploring more. It was my first grow as well, in soil, no nutes, 5 oz for two plants.. my tent was 2x4x5 with 2 p300 led grow lights, actually was using one with my white widows, now using two in same tent for my northern lights, and it will stay that way, much better coverage. It was a pretty forgiving plant for me, best of luck and happy growing, its easier then it looks or sounds, I never thought Id get to harvest, let alone have great smoke in the end. You'll be just fine I'm sure
