Where you can buy our seeds

Right now we have our seeds for sale at these select dispensaries throughout Oregon!







Thank you for choosing Green Source Gardens genetics! All of our seeds are bred outdoors in the natural light cycle (we do not use grow lights of any sort) and are selected for finishing traits tailored to Oregon’s growing climate.

How to Care for Your Seeds

*We recommend starting seeds during the second quarter/waxing moon in April*

To Germinate:

Mix water and aloe with a little saliva to form a germination soak! Amylase in your spit helps kick start the germination process by acting as an enzyme to begin the breakdown of the germ. It also provides your DNA to the seeds, so they can get to know you. Soak seeds overnight (8-12 hours) in this solution at 65-70 degrees F°. This soaking gives the seeds adequate water penetration and encourages easy germination. After the soak, plant your seeds just below the surface of your soil and water in. Expect seeds to emerge from the soil in 3-10 days, some seeds take a little longer to emerge.

For Planting:

For direct seeding: plant seeds outside during the second quarter waxing moon (the week before the full moon) in May or June.

For transplanting: plant seeds in a 4”x 4” soil pot, when roots begin to appear at the bottom of the container (two – three weeks), up pot into a one gallon soil pot.

Sexing: 2 months after germination (early June if you started your seeds in April) plants will generally begin to show their sex.

It is best to wait until you have clearly sexed female plant before transplanting out into the garden.

Breeding Information

We practice many styles of breeding. Depending on which seeds you have purchased from us, here is some extra information about how they were created and for what purpose.

IBLs (inbred lines) are generally more stable as they have been selected over several generations for particular traits. IBLs are generally not as productive or resilient as hybrids. However, IBLs are ideal for breeding to other genetics lines in order to introduce stabilized traits into hybrids of their own.

Poly-Hybrids are seeds of mixed genetic background, therefore less genetically stable and present more potential phenotypes. They are generally vigorous, hardy and less predictable. Poly-hybrids will vary in finishing times within the different phenotype expressions.

F1 hybrids have two stable IBLs (from different genetic backgrounds) as parents. Crossing one IBL to a different IBL is how true F1 Hybrids are created. The resulting offspring of F1 hybrids are stable and productive. F1 hybrids are ideal for commercial production seed lines, pairing stability with hybrid vigor.

F2 Generation Breeding F1s within the same line (sibling crosses) will result in less stable F2 offspring. These offspring show more recessive traits. F2s are great to select for further inbreeding but less reliable from a production standpoint due to the variance in phenotype expression.

We love all seeds. We believe they all have value. The price difference in our seeds is based on the amount of time and energy that has gone into breeding them.

Poly-hybrids are the easiest to create, therefore will be the least expensive option.

IBLs take much more time and selection to create, therefore will be more expensive

F1s will generally be the most expensive. This is because in order to create true F1s you need to have created 2 IBLs of different genetic backgrounds and cross them to create a new stable expression.

*Often in cannabis people make a cross and regardless of parental lineage call it an F1 even though the parental lineage are polyhybrids this does not result in true F1’s and creates offspring that expresses many phenotypes and are less stable, these are just polyhybrids not F1s. Make sure when you are buysing seeds to understand these terms and what they mean to best fit your growing needs.*
