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.

I see someone is going to be a very busy person in the greenhouse this summer. :grinning: :+1:

This sounds like an excellent project with a plan

Indeed! I had to simplify my plans. I have two other breeding projects that I wanted to include, but I decided to run those next year.

What type of greenhouse are you growing in? When running a green house does one need an ac unit to help offset the heat in the greenhouse?

The current greenhouse has doors, vents, and fans. Heat isn’t a problem.

In the past, when I grew in simpler hoop houses, I used a shade cloth on the hottest days of the year. Ultimately it depends on the plants. Some strains can easily withstand 100F.

I like big hunts and I cannot lie.

Happy hunting and selecting. :sunglasses: :vulcan_salute:

I’m going to have to do some research on this. Does it help keep down on the pest. I have a solid indoor setup. I just can’t deny the itch to go something outdoors.

Its a great pest deterrent. The only thing that you will have to look out for is powder mildew, especially towards the end of the grow. As long as you have good air flow and good genetics, it shouldn’t be a problem.

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.

Some interesting seedlings. A few of them are already showing the purple leaf pheno.
Also noticing that some of them have three blades on their first set of true leaves.

Almost time to transplant into quart containers.

I found an old picture of the F2 Valley Ice that I bred into the F3. It was black… outdoors. Hoping to find another one of these in the future.

That thing right there. Good lord. I’d love to grow something black like that

If I manage to isolate that pheno, and stabilize it, I will share the beans with anyone who wants them. :sunglasses:

The temps have been pretty low at night. Its definitely hardening the seedlings.

I think I might have one plant with a black leaf pheno. The camera isn’t capturing the right color. Its way darker than what is seen in the picture. Im going to clean it up and grow it indoors. Super curious about this little one.


I made sure to remove all the soil, and spray the plant down with some soap water. No pests allowed indoors. :grin:

Soapy water can be an effective, non-toxic way to control or eliminate red mites, particularly clover mites and spider mites, on plants and in homes. It works by breaking down the mite’s waxy outer coating, causing them to dehydrate and die.
