Strain name: Grapey Walter
Generation: F1
Type: Auto – Feminised
Genetic Heritage: Grape Crinkle x Walter White
Project introduction and Overview:
Grapey Walter: MG Weather Forecast – Predicted front of high terps with a frost factor of 10!
Grapey Walter was initially released as part of our second line up of Illuminautos in 2016, she sold out pretty quickly, so we couldn’t resist to bring her back as a Limited Edition to give more people a chance to grow and love her!
Grapey Walter is a combination of two of our frostiest strains ever, our Grape Crinkle Artisanal (now extinct) and one of our favourite Original strains, Walter White. Let’s get it straight from the off, she doesn’t disappoint.
Grape Crinkle was a strange little character of a plant, sometimes displaying slightly freaky deeky growth patterns and flower formations, however, she oozes frost like no other and is super rich in terpenes to match. By mating her with Walter White, a lot of these oddities have been smoothed out, just retaining those delectable, powerful aromas and ridiculous resin content.
This is a super nice strain and no doubt will bring a lot of amazement and fun to your autoflower garden. Make sure not to overlook this offering, you won’t regret it!
Strain behaviour and structure:
Grapey Walter is a medium sized plant, naturally she grows with a dominant and thick main cola with decent satellite branching. However with a little light manipulation, you can train her so she spreads that weight across those branches.
The end result is a very respectable yield with a high flower/plant ratio.
She is a hybrid of mostly indica characteristics with a dash of some sativa traits. She’s not a difficult variety to grow and in a good environment will really reward you with some fine fruits.
Grapey Walter is an absolutely next level, quality automatic; some of the whitest, stickiest resin smothering both flowers and fans. With a high level of aroma and oozing exotic terpenes, she can also turn on the colours late in flower, meaning this is a really beautiful specimen on every level.
Trimming and processing isn’t a torrid affair either, and this is a super strain to make exceptional concentrates from.

    If I could give zero stars I would. Started flowering at 3 inches tall. High germination rate but definitely some issues with genetics. I’ll just wait for magic strains.
