That's what they said: "Analysis of the resulting dried buds showed that some varieties had seen an increase of THC of up to 30%..."

Worst case, it doesn't help. Best case, 30% more THC. I'm gonna see if either of my currently-available strains benefits. I'll have to save some buds from when I didn't have the long dark period and see if I can tell any difference. Unfortunately, my only THC testing equipment are my eyes and lungs and brain, and they aren't very accurate, but if I smoke a lot maybe I'll be able to tell if there's a difference. And if I can't, well, I'll be stoned a lot!
