Ok, thanks for the advice, i have read that turning the lights off stresses the plant thus creating more jasmonic acid causing the plant to increse its defences which are in this case THC and other compounds, but i agree at what cost maybe the extra light would have made the buds swell a bit incresing yield. One of my fellow growers tried using a pure pharm grade jasmonic acid on his plants in small doses during the flower cycle it did increse potency some but also made some strange looking buds, but at $8,910 for 50mg and $600 shipping (no bull shit look it up and get a quote) not worth it to me i will stick with natural growing.
If you have deep pockets and want to try this stuff go SynFine's web sight (they sell alot of other crazy shit too like pure delta9-tetrahydrocannabinol for reasearch)
