I've started a habit over the last couple of years of taking notes when I hear something interesting so I can return to it later for a more in-depth look at things. Some of the notes make no sense but some offer more insight into things I'm currently learning. These are some of the notes I've collected about breeding/chucking. I'll admit I removed a few because I'm not ready to share them, but I got them from reading books and journals so you can find them there too. (You should be reading books and not getting your information from a stoner on the internet!) While these notes should not be used as a how-to, I do hope to hear other's opinions or theories on breeding. What would you add to this list? What would you delete? and why? Let's get some useful notes in here.
Feminizing seeds.
Sts spray. Flower the donor plant 2 weeks before the receiving plants. Spray donor plant once at flip and follow up every 10 days. (Spray up to three times.) If timed right the receiving plants should be 3-4 weeks in by the time your donor plant starts pollinating the room.
Locking down traits by S1. (Large selection required/perfered.)
Self pollinate any female to create a batch of S1 seeds. These seeds will resemble the female used with some variation. Find the phenotype that has the traits you want to further lockdown, this will be the next female we use to create our S2 seed stock. For the S2 we'll follow the same steps as before just using our S1 pheno plant. Self pollinate our S1 female to create a batch of S2 seeds. These seeds will resemble the S1 female used with less variation than the first batch. Find the phenotype that has the traits you want to further lockdown, this will be the next female we use to create our S3 seed stock. For the S3 we'll follow the same steps as before just using our S2 pheno plant. Self pollinate our S2 female to create a batch of S3 seeds. These seeds will resemble the S2 female used with far less variation than the S1 or S2 batch.
Male reversal.
To reverse males, use Monterey Florel to spray the leaves. *** I need more information on treatment and dilution.
Plant pollination.
Allow pollinated plants to remain in the conception room for 24 hours after conception. After 24hours the pollinated plant can be sprayed with water to eliminate any rogue pollen and placed back into the main flower room. If done correctly you should not worry about stray pollen. 42 days of flower time is required after pollination to ensure fully mature seeds.
Seed quality vs. quantity.
Early pollination (Day 7-20)= Higher quality seeds. Seeds will be bigger, have a higher germ rate, and better female to male ratio. Later pollination (Day 21-30)= Higher quantity of seeds. Seeds will be smaller, have a decent germ rate, and closer to a 50/50 female to male ratio. Male pollen is most viable in weeks 3-5.
Cubing (I'm not really fond of this method)
The theory of cubing is as follows. You have a plant you want to make a (P1) true-breeding strain. This plant will be backcrossed to 6 times. You start by breeding it with another (P2) plant, preferably a plant that looks different to make it easier to weed out later. The seeds from this cross will be P1-50%/P2-50% of the parents' genetics. Grow these seeds and search out a new mate to backcross to the P1 true breeder. The seeds from this pairing will be P1-75%/P2-25% of the parents' genetics. Grow these seeds and search out a new mate to backcross to the P1 true breeder. The seeds from this pairing will be P1-87.5%/P2-12.5% of the parents' genetics. Continue this pattern for 6 total backcrosses back to the P1 will lock down a 99% pure P1. P50, P75, P88, P94, P97, P99
