How can I use regular seeds outdoors without wasting soil on males?

Probably not but I guess you could kill the male idk if the decaying dead male roots will mess with the living.

 

Build a raised bed.

 

Heres 10 plants in 2 pots.
And 3 plants in one pot.
It's not just the roots that get tangled sometimes.

 

Get female seeds.
Boreal has a spring special on for Blue Jag fem @ 100 for $100.

The only reason you should get regular seed is if you want to make your own. Mind you, some purists say regular seed makes better weed. But I don't believe it.

 

So you absolutely can't start inside? If that's the case, there is one option. You could set up a small propagation tray in a shady area of the woods, start your seeds in peat pods planted into a solo cup filled with soil, send in a sample of one of the cotyledons from each seedling for genetic sex testing, and keep an eye on the seedlings until you get your results back.

Depending on how long that takes, you may have to veg a bit in the solo cups before transplanting to your final holes, but you will know which ones are females. The only thing it doesn't tell you is if they'll be hermies, so you still have to watch for that.

The reason I recommend placing the peat pods in the solo cups is simply to prevent them from drying out too fast. If you wanted to try something different you could place the peat pods in straight perlite in the solo cups, melt holes in the bottoms and sides of the cups, and place the cups in a shallow tray of water. This should allow the seedlings to wick up as much water as they need, while allowing for plenty of oxygen in the root zone. The only thing to look out for here would be leaving them too long and having a mess of roots in the perlite. When I clone with this method and leave the clones in too long, the roots fill out the cups completely.
