Cleaning Grow Room after Open Pollenation

I am looking for the different methods you all use after doing an open pollination in a grow room to insure you have all the remaining pollen cleaned and removed before the next run.

Currently, I would typically isolate the male, and collect the pollen for individual dusting of bud sites with a paint brush. After the grow, I would just wipe down the room with some environmentally friendly household cleaner with a small amount of bleach added. Since I am introducing very small amounts of pollen with this method it has been working.

The problem has been that I do not have two growing areas so I must isolate the male under less than ideal conditions (e outside, or in a window with no supplemental light) This usually leads to the male pollen not being ready until after the peak pollination window has already passed. So I end up storing the pollen in the freezer for later use. This is OK but then that unique cross I was trying to make during that cycle is lost.

So back to my original question. I plan to try an open pollenation run next time leaving the male in the flowering room with the females. This will introduce a lot more pollen into the room so I am looking for your suggestions and techniques of cleaning the room after the run to be sure I remove and eliminnate any remaining pollen so it is not in the environment for the next cycle.

I would probably still ultimately remove the male after having only a few pollen sacks open so as not to produce too many seeds.

I have thought about using my same method of household cleaner and bleach with a double wipe down. Has anyone used any other cleaning or isolation techniques.

It will be expecially important my next run as I plan to do an open pollenation with some Autos. I want to be sure I eliminate any of the Auto pollen for future seed runs so I do not introduce the Auto trait to my non auto varieties.

Thank you all for your input.

...yeah man, first, i'm no expert so don't take this as gospel but i'm pretty sure pollen is only viable for a relatively short period of time and that it will degrade before it can become a problem for you in the following run, ...with proper handling and storage it can be held in a viable state for a considerable time but i think not in your situation.

...anyway, here is a link to a simple male isolation chamber that should allow you to flower a male and harvest his pollen so you can target pollinate.

i plan on doing multiple controlled pollinations by pruning my males to just 1 or two branches and sealing them off with sheets of typing paper DIY bags to catch the pollen from each male i'll be using, and just cutting the stems when i'm ready to collect the pollen. you need to use paper so the plants can transpire, plastic would only suffocate the plants and give you ruined damp pollen. it's the same idea as an isolation chamber, only easier and cheaper, and lets you keep your males in the same room on the sidelines. then, when you collect the pollen, you can just brush it on as many buds as you want pollinated.

cleaning a room after an open pollination is almost un-necessary. right after i open sprayed everything in my room with a C99 male and harvested, i started another grow and only a couple beans showed up, possibly from my highland thai hermie that finally started flowering when it's room mates were harvested. pollen isn't very durable, heat destroys it, moisture destroys it, and i seem to recall that it has only a month's viability at room temps, but remember a procedure to kill all of the pollen in a grow room, just mist it down with a spray bottle, then the moisture will ruin it. the procedure might have also included a bleach solution, but just getting your walls and carpet damp should be adequate.

man do i wish i still had my copy of indoor MJ horticulture! that guide covered more than the two others i bought put together.

Thanks Hazy for the additional ideas and input.

J.A.B. how did you cut your enclosure? I tried using an exacto knife but the plastic was brittle and split right down the side. I am thinking a jig saw may do a better job.

The purple filters do seem to really restrict the airflow of the fan. I guess I will just need to give it a try. At worst case I will only cook a couple males!
