When I did a grow a few years ago now, we tried throwing in 2 Bubblegum plants in the mix, but sadly, they turned out to be male, but we grew them in a seprate room anyways. We dried them out, and out of 2, full blown male plants, about 5ft in height, we got maybe 4grams of low grade hash from it. It wasn't mind blowing stuff either and that 4grams was gone in about 2 hrs.

It just isn't worth the time to fully grow out a male plant. You'd have better success starting again from clone or seed than spend all that time and energy, to get so little. You could do what we did though and just grow them in a seperate room anyways away from the females. We didn't have any lights set up or anything, we just left them in a sunny room, but IMO, it isn't worth all that time to grow out a male plant.
