3. Big producers create feminized seeds by inducing male flowers on female plants using sprayed on chemicals, typically gibberellic acid or colloidal silver (colloidal silver is cheaper and thus more commonly used). Some use hormones instead to achieve the same result. A cross using pollen from these flowers also produces feminized seeds. Some home growers use this method too, by manufacturing their own silverthiosulphate using chemicals sold for photo developing.
If you’re thinking that feminized seeds sounds too good to be true, here are the (slightly) dirty facts: Not all feminized seeds are created equal. There are three ways of making feminized seeds and they do not produce the same results. The first two ways are simple; you can do them at home. The last requires a bit more chemistry savvy and is often used by large companies producing seeds in quantity. Here’s how it’s done:
Just what they sound like. These are marijuana seeds that produce only female plants. The highest quality feminized seeds produce 99.9% female plants.
But… Feminized seeds aren’t perfect.
1. Marijuana has evolved a clever trick to help it stay ahead in the survival of the fittest game. When female plants are stressed they can turn into hermaphrodites, growing male flowers in addition to their female flowers. A cross between a hermaphrodite and any other plant tends to result in female offspring. This is how the original feminized seeds were produced.
2. Another little trick of evolution allows a female plant that remains unpollinated to grow tiny male flowers and self-pollinate, usually producing feminized seeds.
Why do you care how feminized seeds were made? Plants, like all organisms, pass on many genetic traits to their offspring. Some females are more prone to turn hermaphrodite than others. Not all will produce the mini male flower as a last ditch propagation effort. These tendencies get passed on to the seeds. What does that mean to you? Feminized seeds produced from naturally occurring hermaphrodites will have a stronger tendency to turn into hermaphrodites themselves. This means male flowers. Exactly what you were trying to avoid by buying feminized seeds! This is not the end of the world. You have options. You can buy or make seeds using chemicals or hormones, which will be less likely to turn hermaphroditic. However, not all feminized seeds on the market are of the same quality. Using a professional, reliable seeds producer is essential to reduce the occurrence of hermaphrodites.

Northern Lights is pretty much a household name. Among cannabis enthusiasts, Northern Lights is a famed strain that almost everyone knows. It possesses 90% indica genetics with the effects to match, producing a stoned body high that will leave a smile plastered to your face.
Luckily, feminized seeds are there to save the day. Feminized seeds ensure that 100% of the crop is female, preventing pollination and waste.
1 – Northern Lights
It’s a moderately tricky strain to grow. While not the easiest around, it’s still an ideal strain for intermediate growers who are looking to progress onto something slightly trickier. Amnesia Haze prefers a balmy Mediterranean climate; however, it’s definitely best to grow it indoors.
Royal Queen Seeds now stocks a feminized version of the classic White Widow strain. It even recommends this strain specifically to new growers; take their word for it!
Amnesia Haze is another famed strain, this time a delightful sativa. It hails from Holland, a land known for high-quality buds. As a top-shelf sativa, you can expect pleasant effects during the high, including euphoria, laughter, and energy. With a 21% THC content, you need to be careful with this one.
