No its not. The same buds same grower hydro vs rols, hydro turns airy when it dries out, no matter how many sugars and oils you feed, rols stays thick and caked up once the moisture is gone, no sugar contaminants needed to fool anyone, the buds never turn to powder, just caked up calyx.
Hydro is mostly plant matter water and thc. No resins, no oils. Rols contains all the other juices that give a high Brix count in the refractometer.
The refractometer proves hydro is Diet RC Cola vs Mexican CocaCola at best. The refractometer takes subjectivity out of the equation. I even test for foreign (non cannabis) sugar sources when I taste them, to prove its not subjective, my tongue just works right and knows all of the hydro industries dirty gimmick to fool gullible people with money.
Hydro growers are screwing with diabetics health trying to make their buds sugary. Its always detectable. You cant get the real flavors from hydro. Its impossible.
