You are asking the right questions and have a fair plan. I have a few suggestions. It is very easy for pollen inside a house to get to another location inside. If exterior venting is present, I suggest the male should be locate near or right at the exhaust vent. Possibly outside on a covered porch and harvest pollen as needed or save in refrigerator in air tight container. Preferably light proof. Light does degrade pollen. Like was stated above, just do a little of the bottom, one branch and mark it (I use a loose zip tie). I pollenate in the 3rd to 4th week of flower.

There are threads about storage of pollen and seeds in the forum, check them out....and yes welcome, we are here to assist those who are willing to learn.
