The record · 3 sections

We dedicate this herb to the majestic oak tree and to the earth in which it stands.

Our latest hybrid is the Oak Tree which extends her roots all the way out to Oakland, California.

The SR-71 Purple Kush is one of our favorite Oakland purps for her forests of resin, dark color and captivating high.

The Joseph increases the frost factor and every phenotype is tastier and frostier than the next.

Each our diamond bud smells rich with grape caramel and diesel.

The lavender vapors expand the channels and fill us with healing vibrations.

Expect fast finishing phenotypes, some finished at 50 days fully flowered.

Many phenotypes stayed bushy and low with big dense colas.

All are very vigorous and fast finishing.

Not all phenotypes turn purple but expect intense flavor and resin in every phenotype.

The Oak Tree is a perfect hybrid, providing that full body relaxation while easily maintaining an upbeat social vibe and creativity throughout the day.
