Cannabis Seed Strains seen at Grow Sciences

Feminized seeds are obtained from plants that have been treated with colloidal silver or silver thiosulfate. This process forces the germinating seed to develop as a female, which is good for growers.

Absolutely! Feminized seeds take the guess work out of the number of seeds you need to germinate, and you won't have to worry about males pollinating your ladies, which will significantly decrease the quality and yield of your harvest.

Unlike regular seeds, autoflower seeds have been crossed with the ruderalis cannabis species which forces them to flower when they're old enough, not in response to the light duration. This will take the guess work out of when to switch from veg growth to flowering in your grow.

People always wonder about the legal risk of purchasing cannabis seeds through the mail. Legitimate seed vendors (including those we recommend) ship discreetly to most locations. Seeds can be stopped by customs, but this doesn’t happen often. You also want to make sure that wherever you decide to purchase your seeds will also ship to your country. This information should be transparent and available on the vendor’s website.

There are a number of good seed vendors out there. Our recommendations are established companies with great customer reviews so you know you’re purchasing quality seeds.

If you’re contacted via social media to purchase seeds, chances are you’ve been targeted for a scam. We recommend using established cannabis seed vendors such as those linked below.

1. Do you recognize the name of the company name?
   Branding goes a long way and a recognized, established brand is something to consider when purchasing seeds online.
2. What are customers saying in their reviews? Did they receive their seeds? Were they high quality?
   Researching these questions will increase your chances of being happy with your seed purchase.
3. Do you know anybody who has used them as their supplier?
   Word of mouth recommendations are very powerful in the cannabis community. Someone else's first hand experience can be helpful if you aren't sure about which brand of seeds to purchase.
4. What’s their return or refund policy?
   A good seed shop should at least have generally positive reviews and a well-defined refund or exchange policy.

A good seed vendor should only ship out quality seeds. Here is what to look for when assessing their overall health.

• Dark color with stripes or spots (white or green seeds are too immature to sprout).
• Waxy, shiny coating: While not critical, this is a sign that the seed is healthy.
• Hard shell: You should be able to apply light finger pressure without the seed cracking. If the seed buckles under light pressure, the seed is either infertile or dead.
• No cracks: Healthy seeds will have their seed coat intact without damage. Check for holes too, as insect pests may dig into seeds for the delicious starch.
