It’s pretty easy to sex most indoor strains long before they go into full bloom. Below are some illustrations of 28 day old plants started from seed that are expressing early preflower.

Plants can be sexed in a month or so this way which allows you to cull males so you can start more plants. In Michigan you are only allowed 12 marijuana plants per patient. You don’t want to waste any time and money growing males.

If you have a clone sexing isn’t necessary but if you have to start from seed knowing how to sex plants in early preflower will help you get on to your next grow that much quicker.
