Hydro, or "dro" is nothing special. Hydro is just short for Hydroponics, a method of growing cannabis. All it is is a method used with no soil, just water. It sends the nutes or ferts straight to the root and all that does is it grows mass amounts of green in a shorter amount of time. That's all. Doesn't mean it's super duper pot as it is commonly grown with chemicals.

I've had pure Blueberry before, many Skunk hybrids that included Black Haze and White Widow. The most potent high end that I've come across was Manatuska Thunderfuck, an Alaskan strain.

Then I've had the typical BC coast smoke like Pineapple, Mighty Mite, Island Skunk, etc...All good smoke.
