is it possible for multiple males to pollinate one female

is it possible for multiple males to pollinate a female ? got a white dwarf female ,three lowryder mixed males and a random sativa male

Yes. Those males will tag team the crap out of your female.

This doesn't mean that some seeds will be white dwarf x lowrider x rand sativa, but you will end up with all of these combos: dwarf x lowrider A, dwarf x lowrider B, dwarf x lowrider C, and dwarf x rand sativa.

haha thats what i imagined .thanx man

Just a thought, if you selectively pollinate individual branches with your males you can keep all the crosses seperate. I use this method often especially if I have two competing males of the same strain or to make different crosses with the same plant.
Good Luck

Yes, i just did so, i have marked the nuggets that i pollinated separately as my usual method is taking a bag and covering the budsite and then rubbing the pollen in with a brush, waiting 45 min and then removing the bag encase not to spread pollen needlessly. i crossed 5 males with one female and the seeds are all slightly different, results one would expect.

the paint brush technique for selective breeding is better than random spraying, but you can still get some contamination. if you want to be sure you get separate breeds, take cuttings from your mom and breed to each male in a different location or one at a time by freezing your pollen. if you do that though, you'll only get to thaw an envelope once to pollinate, so keep a few of each male if you wanted to re use them, or take male cuttings too.

man... that dusty info has been in my head since the late 80s!
