F4 Valley Ice _ 72 beans

After much contemplation, ive decided that this year's greenhouse crop will be simply one tray of F4 Valley Ice (MTF X SFV OG) seed.

My general plan is quite simple. I will keep the plants in small pots, and transplant them into the raised bed that is in the greenhouse, around late July. This way the plants wont exceed 5 ft in height. It will make the whole grow much easier.

This is a pheno hunt, with two objectives
1. Make F5 seeds
2. Backcross a vigorous purple male to the f3 Valley Ice mother.


** Important information to document, for my own records**
The Purple F3 male that was selected to create the F4 seeds has proven to possess strong genetics. From my small tests indoors, ive gathered that the purple flower pheno rate in the progeny of the F1 Valley Ice x Brandywine is 75%.
I am expecting 90% of the F4 Valley Ice progeny to display purple flowers.
Selection of the F4 VI male should be rather easy. I am confident that I will find a male plant that is displaying all the same characteristics of the F3 Mother.

Only 4 beans didn't pop...

Ive plucked the runts and weak looking seedlings. Its down to 52 plants. One plant in particular clearly has strong sativa genetics. Its lanky and tall, with thin long blades.

the only problem with that is, acording to the cannabis breaders bibal, is you will get loads of males one end and some females the other. they did an experiment as i remember

What exactly are you referring to? Are you implying that the runts and weak plants often turn out to be females? If so, I still wouldn't select them for breeding.

Its an interesting thought. I wonder if the male count will be higher than normal? Only time will tell.

With a large pheno hunt, what traits are you specifically looking for to make your crosses and culls? I’m curious how the physical selection and culling process compares to the old fashioned way of “smoke-testing” everything and then going back to breed with some “favorite” plants. Have you been able to predict how the plant may smoke by looking at a handful of characteristics, after breeding the line for a few generations? Have you been able to make any correlations ? This is obviously a much faster method to an end result.

At the top of my list, for my selection process
1. Vigor
2. Overall plant and bud structure
3. Fruity terp profile

Im breeding this strain with one specific goal. It must do well outdoors in this pnw climate.

There is still a lot of genetic diversity in the Valley Ice. The MTF genes has a lot of variety. Ive seen ruderalis, sativa, and indica plants within that gene pool. Its freaking amazing.

In all honesty, I haven't found a plant with the effects that im after. Most of them are hard hitting indicas. The Mother plant that produced the F4 seeds, has a stony high that makes me drowsy. Its actually put me to sleep a few times.
The deep purple Valley Ice plant that is sativa leaning has a pleasant effect, its uplifting with a mild body sensation. Ive decided to take that plant in a different direction though. Im going to enhance the Sativa genetics, by crossing it with SSH and Oaxacan.
Its turned into a separate project.
