As a long time grower, I find the cost of feminized seeds to be a huge rip off.
If you really want to grow quality plants from the first grow you need to read/study first. To this day I pull out a book I bought some 10 years ago Indoor Marijuana Horticulture The Indoor Bible.
I find it really good bathroom reading, as I learn more with each reading.
Page 261 is titled Feminized Cannabis Seeds. In 1998 Dutch Passion introduced Feminized Seeds, and while many growers had 100% success it soon became apparent that environmental factors play a role on an individual's success.
You can increase the number of females from non-feminized seeds by:
Increasing N increases females
Lower P increases females
Low temps increase females
High humidity increases females
More BLUE light increases females
Fewer hours of daylight increase females (~14). So much for growing under 18-24 hours.
Any form of stress increases males
So, if you spend the money for feminized seeds and do the opposite of these tips, you will reduce the percentage of females.
