Yes, this is a male plant.
It will pollinate your females if they are in flower.
Unless you want seeds, removing him from your grow space is your only option.
You also don't want the male flowers opening in your grow area, the pollen is very fine and can last quite a while, meaning even in 2-3 months, you run the risk of the pollen creating seeds in your females when they flower.
Putting him outside and picking a few male flowers when they are about to open is one way to collect pollen, if you are interested in breeding. Just keep the "balls" in a small bowl and in a dark windless space like a kitchen cupboard and in a day or 3 they will open and release their pollen. It is then easy to remove the spent flowers and leave behind the yellow pollen. I then mix the pollen half and half with corn flour, this extends it and does not cause any loss of pollination ability. As each seeds only needs one pollen grain for fertilization to occur, mixing it with flour is of no consequence. I have found a small paint brush as the best way of applying the pollen to young, fresh female flowers, using anything else and the pollen sticks to it too much. Make sure to switch any fans off before applying the pollen, otherwise it will blow everywhere and you will have seeds everywhere. I like to use the lowest branches to pollinate, that way if the seeds are not ready, you can harvest the top of the plant and leave the lower pollinated branches to finish off. Seeds maturation takes about 4 weeks, but I like to give 5-6 weeks to be safe, so pollinating early is vital. Even very young "tufts" of white pistils will produce many, many seeds, so there is no need to wait for the female flowers to grow very big before pollination. 8-12 small tufts of white pistils will generally produce 200-300 seeds. Waiting an hour after applying the pollen will ensure enough time for fertilization to occur, after this you can spritz the excess pollen/flour mixture with plain water and this will effectively kill any remaining pollen and prevent stray pollination when you switch your fans back on. I like to tie a piece of string to the branches that I pollinate to make remembering and identification easier - different colours for different plants of course! Write everything down too, don't rely on memory!! This method will produce a limited number of seeds with known parentage and could be the first step in creating a special "That 70s Dude" strains of super buds. Remember too, seeds made with regular male pollen and regular female flowers will produce regular seeds. Also, by pollinating early, this can prevent hermaphroditism, as the females will have hormones in their systems telling them that seeds are developing, so there is no need to turn hermaphrodite and self impregnate. Breeding your own strains is exciting and extremely satisfying, naming them is also huge fun. Growing flowers of your own breeding and having people compliment you is the icing on the cake. Give it a go!
