Umm... couple o' things...

Trics are not a defense against cold weather. As an annuals, the only " defense" against damaging cold that cannabis sp. possess is reproductive selection toward earlier flowering individuals. They adapt to local conditions, rather than fighting them.

Remember- the plant's only goal is to produce viable seed ( or, more precisely, viable reassortments of it's genome) - a sunscreen which happens to have , under some circumstances, psychoactive effects on some mammals is really incidental, as far as preventing damage to the seed chromosome. The only way in which " potency" is a reproductive advantage is that humans are more likely to husband the seed of more potent parents

Ain't no such thing as 30% THC (wet weight) in any strain, anywhere- pre-decarboxylated d9 acid, at room temperature, is gonna be a liquid. Given that we can expect 80% weight loss during the drying period, bud @ 30%(wet weight) THC would be either a gel or a slurry- I'm not sure which. Anybody got a Merck handy?

I know that breeders will claim very high %'s- All I can say is that they must be using some neat math.
rhizome Reviewed by rhizome on . Maximising THC content of an outdoor grow? So next year is going to be my second grow. I wont have ALOT of plants, but hopefully more will sprout next year than did this year. The thing is, due to privacy issues the only place I can grow is out in my woods. So I know with indoor hydroponic setups and the like you can fine tune everything to maximize the THC content- since everything in under your control. But what variables are (at least somewhat) under your control when you grow outdoors? And what are the best ways to use them to Rating: 5
