hydro is only faster when u see how big they get in little time compared to soil of the same time... check ur trichs.. color meant in buds not the red stigmas..
Seroulsly tho, u can control the high with when you harvest based on Trichome color but that defeats the purpose of the Plants genetics, I say grab when you know the plant is at its Peak~~which equals, just starting to turn amber. You wanna speady High, grow a sativa, want some couch lock shit, grab a Indica, but get whatever plant you got when it is the most pontent~IMO
