The switch to 12/12 is based on fall approaching in Northern Latitudes, when the length of the day goes from having around 14/15 hours of daylight in summer to 9/10 hours of daylight in winter. Even if you're at 20 degrees north, there's enough of a shift between the length of a day during the summer and winter for your plants to "know" when to flower. As an example, I'll use Puebla, Mexico. It's at 20 degrees 11 minutes longitude...about what you're talking about. In mid-June, the day is 13 and half hours long. By mid-September, it's an hour and a half shorter. The plant will flower when it senses the day getting shorter. The farther from the equator, the faster that drop happens. this means shorter grow seasons. Shorter grow seasons = less veg time and smaller plants. Longer grow seasons = longer veg time and plant growth. Essentially, where you are, you'll have to wait a while for your plants--because you've got a really long grow seasons--but you'll get big ass plants.

F1 and F2 are used to refer to how uniform a hybrid plant is. A simple way of looking at it is with human eye color. A man with "pure" straight hair marries a woman with "pure" curly hair and they have kids. If straight hair is dominant, all of their kids will have straight hair. You get a uniform trait. The kids are considered to be the F1 generation of the hybrid. But if one of the F1 kids with straight hair married someone with straight hair from another family that was also an F1, they have a 1 in 4 chance of their child having the recessive trait...in this case, curly hair. So you got more variance with their kids, who are the F2 generation. Now multiply that by hundreds of traits. The more generations you have that get away from pure stock (F2, F3, F4), the more variance you have. The point of plant genetics is to have uniform plants with good qualities and keep out the variance. If a plant is "stable" or "uniform," it means it's still near the original F1. Older strains, like Northern Lights, have been bred pretty true...it's hard to go wrong with something like that.

As to mold and stuff like that...there's too much to choose from to recommend one strain. Just do some research and see what appeals to you.
Roughrider Reviewed by Roughrider on . C99 Does anyone know where I can find original c99 seeds? I don't understand genetics, but is it possible to find an "original" c99 mommy in a pack of f5's or f whatevers? If so, roughly how many packs would I have to grow out to find what BrosGrimm called c99? Sorry, I don't understand genetics or breeding at all, I just want this strain. Also, can anyone recomend a fast, mold-resistant strain for me? And more...I live around 20 degrees north of the equator, very hot and humid. How will my Rating: 5
