The flavor is a combination of sweet cookies, citrus, and earthy-sweet resembling ice cream. The effects can be devastatingly potent leaving you firmly locked to the couch, with enough of a cerebral edge to keep you in a creative mindset.

Grow Tips 

  • Due to her extremely loud terpene profile, it is well recommended to use carbon filters up to the job. Especially when drying the buds, the aroma can become seriously overwhelming. 
  • Defoliating certain Indica shaped fan leaves will help light penetrate into the canopy. This will allow the lowest parts of the plant to grow large-sized buds. 
  • Get those trim bags or sifting screens ready, as she is unbelievably resinous. A wise choice for the connoisseur hash maker or extract artist.

4. Orange Sherbert Auto - 24% THC

A sativa dominant strain with massive yielding capabilities, that boasts at THC level of 24%. Despite her Sativa influence, from seed until harvest can take as little as 63-70 days, making this potent powerhouse an excellent choice for anyone looking for monster yields of super sour, orange sherbert terps.

One of our taller autos that can grow as tall as 150cm with a bushy appearance, and when flowering will produce fat, swollen calyx that stacks up with a hard density. Her flavor is superb and can be described as orange candy, sour sherbert, fizzy citrus with hints of a bold orange overtone.
