Growing pot for seeds

They grow plants only for seeds............they can't grow flowers for human consumption. They are seed breeders, not pot producers.

Well, they pollinate a plant and collect the seeds? Yes, they have to worry about contamination, so common sense applies there. Outside is cheaper but tougher to keep isolated from contamination (the "wrong" pollen). Most people don't realize the scale of productions. I made fem seeds and got 1000-1200g from tiny 35-40gram plants. Imagine a 2kg monster outside? 50-75k? As far as breeding at home. Just make sure to do chores in the seed area AFTER you work in the flower area each day. Take a shower and change clothes sometime before re-entering flower area, lol. (or, going anywhere near it). I had a flight of stairs and a couple doors between and did not cross-contaminate with simple common sense rules. Make sure filter on furnace is good enough to filter out pollen. The pollen donator can be removed once its job is done, so it's not like you have a plant dumping pollen every day for a month. .. Maybe 3-5 days before enough pollen sacs open to pepper plants or collect it to apply manually. There's 7-10 days of concern... and after that there's no concern of contaminating other areas.

You don't really need a lot of extra space for a breeding program really. You just need to be able to keep things separated enough to not contaminate areas with rogue genetics. You can get a lot of seeds pollinating just a plant or two. The pheno hunts to find your most desirable candidates can really be as large or small as you want/have the space for.
