That girl looks indica dominate to me. She's got some fairly fat leaves. I'm no expert though.

As far as the male, of course you'll only get seeds if you allow the female to be pollinated by the male. I would think there is a good chance of at least some pollination even at 40 feet apart. Mother nature is good at that sort of thing. It might not be much though... maybe just a few seeds. Again, I'm no expert.

The girl's buds will not be as strong if she is pollinated b/c more energy wiill go to seed creation then resin creation. The more seeds she makes, the less strong her buds will be. But if the plants are looking like they have good genetics, perhaps you will want to pollinate to get more seeds. Then you can try to grow a non-pollinated (sensimilla) plant next time, killing off the males since you already have seeds. You could also collect some male pollen in a bag and attempt to pollinate only a few of her buds so the others keep more of their resin.

Most marijuana plants, especially indicas, do not mind temps at 90 degrees. Just keep them watered when they need it (of course don't over water though).
