Feminizing your seeds can be hard to grasp and extremely confusing. And you don’t want to make a mistake when tending to your carefully grown plants either. So here are some useful tips on how to properly feminize your seeds with aspirin.
Some other methods you may have heard of are the rodelization method and the colloidal silver method. Each of which have their own pros and cons.

Why should you feminize your seeds with aspirin?
Feminizing seeds produces female plants that when left without pollination, create buds and plants higher in CBD and THC. This is the high grade plant the breeders and growers seek out for better highs.
It can also ensure that your growing space produces a higher yield of crop as male plants are difficult to manage and don’t produce the quality a lot of people need.
Also, keeping male plants around carries a risk of them pollinating your female plants.
Once you have your feminized seeds from one plant you can plant hundreds of female plants.
How to feminize your seeds with aspirin – step by step
Follow along to be guided through the process. You will need:
- Aspirin
- Plastic bag
- Paint brush
- Female plant
Step 1: Get your hands on some Tiresias Mist:
Buy some Tiresias Mist
Tiresias Mist is the brand of Aspirin I use for my spraying that I know works but you can also take aspirin tablets and dilute them in water to spray.
I know this bottle works. However, the ratios I have heard of using if you do decide to go the homemade route is one and a half aspirin tablets for every two gallons of water.

Step 2: Wait for pre-flowering
Next you want to wait for the plant you want to spray to pre-flower at around 30 days. You should see little hairs starting to form on the nodes of your female plants when this happ
ens. Pick the plant you want seeds from by picking a good strain and a healthy plant that is a female. You will know it is a female because of the hair like structures mentioned forming at around 30 days.
It is recommended that you pollinate the seeds of the same plant you spray with aspirin rather than using two separate plants and transferring pollen.
This results in more stable seeds that produce plants that grow uniformly and with healthy buds.
Step 3: Wrap with a plastic bag and spray
Take a plastic bag and wrap it around the limb of one of your plants, only leaving one branch exposed for spraying.
The reason for this is because a slight bit of over spray will produce male parts on your plant where you only need one branch of pollen.
Seal the end of the plastic bag that connects to the branch with tape each time.
You want to spray the splits in the branches where new limbs grow out of with one or two sprays each. These nodes are where the new male parts will start to grow from.
Step 4: Rub in aspirin thoroughly
Get a paint brush and rub the aspirin in to the splits and up and down the stems to make sure the aspirin is thoroughly rubbed in.
Spray with aspirin and rub with the paint brush every day for two weeks and remove the plastic bag in between sprays so your plant can still get light to the other branches.
Step 5: Wait for male parts
When you start noticing the male parts to grow you can stop spraying. This should be about 14 days from starting to spray and about 45 days of the plant being alive if grown from seed.
The new male parts should look like this:
Step 6: Shake developed buds
Wait for the male buds to fully develop on the branch you’ve isolated. You will know they are fully grown when they start to open up and you can see pollen inside.
Please note that before you make it to this stage, you have to make sure that this plant is isolated from any other female plants to avoid cross pollination.
Now shake the developed buds on the rest of the female plant buds that would have been developing on the rest of the plant. (The area of the plant you’ve previously covered up with your plastic bag).
Again, it is recommended you do this inside away from any other plants you are trying to grow to avoid cross pollination as pollen is very potent.
You can also use a paint brush again to pollinate your female buds if you do not want to shake or you can also cut off the male bud and shake it around if bending the stem doesn’t transfer pollen effectively.
Step 7: Wait for seeds to grow
Because this male pollen was created on a female plant using aspirin, the pollen will not be effective but will still produce pollinated buds. This means feminized seeds will be produced that are naturally going to fall off of the bud for collection.
Sometimes the seeds won’t fall out in which case a small shake should remove them. This should be done around day 100 to 120 of the growth of your plant and the seeds should be starting to darken.
Where should you store your feminized seeds?
For a very long seed life, treat your seeds with a fungicide or pesticide. This will be useful if you are selling them on as they will stay fresh.
Find out more about the difference between treated and untreated seeds in our article comparing the two. However, this step is by no means essential and seeds should last years without treatment.
The best place to store them is in any air tight container with silica beads inside. These can include old plastic chewing gum packets or zip lock bags with silica beads.
The silica beads will make sure there is no moisture around your seeds. You can then store them in a cool dry place or in the fridge if you want your seeds to last for years to come.
When stores in the right conditions your seeds will last up to 5 years.
