Can I ask do you get your recipe from a retarded children's book because this is not how you make cannabis butter at all. Margerine actually makes horrible canna spread. To the OP yes you can make butter from males but I would only use the parts that have tric's. Most people do not have luck with male butter because there is usually not enough trichs developed on the plant by the time you pull it.Absolutely.
Get yourself a big tub of Country Crock and toss that and the entire plant (roots & all) into a Cuisinart and pulse for about 45 seconds.
Spread it on your toast in the morning and hold on tight.
