haha you guys are funny... actually it doesn't matter at all which way you orientate the seed/tap root into the soil/media.. the plant naturally uses gravity to 'find' its way down into the soil, then the embryo with seed pod attached rises above the surface..etc
In nature those seeds just fall to the ground in any random arrangement and there still is a 50/50 chance of male/female maturation....
Its all this jonesing for a toke that growers want to get every last little detail right, but sometimes you can actually try too hard!
I think the key is to have some sweet herb layin around to smoke while you watch your babies grow.. have some patience, dont tamper with the embryo, smoke some weed, chill out and have fun.
good luck!
