Make your pollen before growing the females you want to make seeds from. Just store the pollen in a stable cool and dry place, like a cupboard in a dark room or hallway without direct sun on any windows and it will remain viable for 2-3 months, (probably even longer), no problem. Do not place it in a freezer or fridge, the moisture will destroy the pollen. Pollinate your chosen female as soon as she has small "tufts" of white pistils formed at the ends of the branches, seeds will need 5-6 weeks to mature properly. Growing a plant and then manipulating it to produce male flowers to fertilize another female plant in the same grow will not give enough time for seed development due to the recipient plant being too far advanced in flowering already and with limited health remaining, or to achieve high fertilization rates due to too many pistils being brown, meaning the seed ovules have already died. Pollinating early will still yield hundreds of seeds if done properly. Mixing the pollen 50/50 with corn flour will extend it if you have limited amounts of pollen, with no loss of fertilization rates and applying the pollen with a small paint brush with short bristles works best, trim them if necessary to about 3mm/eighth of an inch - too much pollen sticks to Q-tips/cotton buds to make them useful.
I would also advise not consuming any part of any plant that you have treated with colloidal silver. While the risks may be small, do you want to be the guinea pig to find out that it is not safe or healthy to consume treated plants? Liver damage is a real risk with colloidal silver.
