This is a special plant. Big Bertha hasn't seen any more darkness than my balcony at night. Always enough light to read by. It get's it's first ray of sun at 10:30 and watches the sunset at 7:00, apartment grown.
I've been following Nebula's manifolding technique with happy results. My last harvest was 2 plants in a 2x2x4.5 tent. It gave me about 75 grams. One of those plants broke a secondary branch early on. The remaining secondary branch produced more than either of the mains and the three branch plant produced more than the four branch. I'm considering doing a cut of one of the secondaries I just debudded. Since BB is absorbing as much ambient light as it can and the sun pretty much goes all the way through, I'm holding on to the fan leaves until right before switching to flower.
