Yummy! Sounds like a nice strain!
In the F2 you'll get more variance because recessive genes come to light. About 25-75% of the plants are similar to the F1 generation, the rest looks like one of their parents (or even like their ancestors, because you used a stabilized hybrid).
If you want to stabilize the variety yourself, this is done by backcrossing. That is, when you keep a F1 plant with the desired characteristics and cross it with a male from the F2. Repeat that with a male from the F3, then the F4 and so on. If all plants of one generation looks more or less the same, you can consider the variety to be stabilized. A stabillized variety can have more than one phenotyp.
If you have a particularly beautiful female, there is an easier way to fix those very characteristics to the next generation. Feminizising is the keyword!
You will need a Collodial-Silver-Generator (basically some .999 silver wire, a jar, some Aquadest and a 9v driver) and a mother plant whose characteristics you want to fix to the new seed generation. Take some cuttings, switch to 12/12h, treat/spray one or two cuttings daily with collodial silver until these get masculine flowers(50-100ppm strength is recommend). Use the pollen of those "males" to fertilize the remaining cuttings. Although the progeny from this process are not really "stabilized," all plants will be identical because they all carry the same genetics.
This saves you many months of work and today this is the most widely used type of seed production!
Positive side effect: all seeds are feminized.
This is an old thread but it shows very well how you use collodial silver to make fem. seeds.
