I documented everything so I will follow the same routine for tomorrow's actual test. Thanks to N2 and thank you Burnt Toast for chiming in. I will post actual results tomorrow. Wish me luck.

-8:00am - took First Check THC Home Test, first pee of the day - failed (no line).
11:00am -after posting on this awesome forum, I started the Dilution Method "test run" and started loading up on Water and Cranberry Juice.
12noon - Pee'd (slight color) like a racehorse, replenishing with more water.
12:15pm - P'd (clear color), followed by more water.
12:50pm - P'd (clear color), followed by downing half of a 32oz Powerade (Lemon Lime flavor) and more water.
1:33pm - P'd (clear color), followed by downing the rest of the Powerade. Also drank more water.
2:00pm - took 10 B-Complex tablets with more water.
2:05pm - P'd (clear color)
2:45pm - P'd (slight yellow/greenish color)
3:13pm - P'd (yellow/greenish color)
3:45pm - P'd midway stream into First Check THC Home Test cup filling it just past the minimum line. Color was same, yellow/greenish. Put the lid on and waited while crossing my fingers. Line showed up this time - PASS!!!
4:15pm - Took another First Check THC Home test, again midstream and PASSED again!!!!! How ironic that it's 4:20pm.
