As long-time fans of the classic skunk strains, we felt Landlocked Funk could add to the amazing selection of skunk genetics by crossing a Lost Coast Skunk from HSO with our Nami. The plan was to reinvigorate the depth of the skunk by adding a level of funk to the mix. This blend exceeded our expectations. The Nami always brings size and trich coverage to anything we have crossed it with. The flower to leaf ratio is one of the best we have ever created. This makes harvest a breeze. Density was off the charts on the spear-shaped buds. She has been grown in a number of environments and under a multitude of growing regimes, and she has handled them all with amazing results. The funk factor that the Nami brought to the mix can’t be understated. From the pepper scent of the classic skunks, she has brought out an incredibly complex bouquet that will impress even the toughest critics. Trichome coverage has even extended to the stems of this beauty. Making it perfect for extraction artists as well as edible makers. Every part of this plant can be used in some form of extraction. Size is something to take into account though. She can get large. We’ve seen an average of 3’ in one and two-gallon containers and as large as 4’ in three-gallon fabric pots. Training is highly encouraged. A perfect candidate for topping, LST and super-cropping. Yields will vary depending on light intensity and nutrient regimen. 2oz can easily be obtained in small grows with that number easily doubling with a larger setup.

Nurple was created by crossing a deep purple BlackBerry Kush with a large and funky Nami. We were looking to add some funkiness and frost to the purple berry kush flavor. We like to think that we got that and more…There are three phenotypes to be found:

  1. Green leaf which switches to new dark purple leafage when entering flower with purple calyxes.
  2. Green leaf with a purple flower.
  3. Green leaf with green flower.

Jogi OG is definitely the new ruler of their collaborative efforts. Her genetics consist of two unreleased strains: Ronin Garden’s Chikara and Magic Strains Alien Overlord. Each of these strains was worked from photoperiod to full auto before being used in this cross. The genetic lineage on both these strains is seriously deep. Please visit for more information.

What does this mean to you the grower? This is by far the most potent and powerful cross from Binary to date. From chem to kush to musk and funk the flavor profile will be a must-have in your garden. She is an excellent candidate for extractions. Or she can be enjoyed in her all-natural flower form.

Plants can easily reach 4 feet tall and yields will be equally commensurate. As with other Binary creations, this will be a limited edition cross so get these beans while you can!

All of these are densely covered with trichomes. A grape pixie stick sugar candy smell during flower will be found amongst all phenos. It is intoxicatingly sweet and mouth-watering. Usually overpowering surrounding plants with that funky sweet aroma. Expect medium size plants with strong growth structure. Great for training (LST, super-cropping) 1 ounce + per plant in favorable conditions. She can be harvested in 8 weeks, 9 weeks if your looking for something more couchlock. High is quick setting with a feeling of relaxation and euphoria good for watching movies or your favorite show. If taking later it can be very good for night time bud right before bed.

Flowering time: average is 70 days
