Nevil's Wreck

Here's the info from the man himself:

Arcata Trainwreck (original "E32? cut) x Nevil's Haze (Northern Lights #5 x Haze A) x Haze C

Created by Scott, founder of Stone Mountain Wellness in Longmont, CO

Flowering times range from 65 days to 115.  The quick finisher is a heavy blend of the two strains.  The longer flowering ones are most Nevil's Haze dominant.  My personal favorite pheno of this strain is the #12 female nicknamed the "Krumholtz Haze".  Krumhotlz is the low scrubby twisted vegetation found just above treeline before the alpine tundra — it is a piney, whorled twisted land of tiny trees and alpine flowers.  #12 earned the nick.  The heavy head feeling pheno you describe is the #14 aka Chunk's Haze.  Grows best in Hydro applications, gets BIG and yeilds heavy for a Sativa.

Amazing flowery Haze taste with some pine elements

Uplifting and highly energetic, this is a strain that makes you want to be active and be outside in nature.  One of the phenotypes has a somewhat strong Indica-like mental effect that makes the energy slightly less useful, but the rest tend to be almost entirely Sativa in effect.

Grows extremely well in hydro and finishes out as a big producer for such a highly Sativa plant.
