This marvelous variety contains up to 30.4% THC and offers one of the best terpene profiles out there in 56 days.

Bud description
Perfection in bud form. Banana Purple Punch buds boast bright-orange hairs and a beautiful mix of purple, pink, and magenta hues that get completely covered in trichomes by harvest time. The medium-sized buds grow extremely dense and stacked on top of each other, making the main cola and side branches look like the tallest purple skyscraper you’ve ever seen. The mouth-watering tropical fruit smell will mesmerize your nostrils before you can even break them open, a truly exceptional strain for those looking to make the tastiest hash and extracts.
Smoke report
This strain is not for the faint of heart. At first, you’ll experience a joyful high that allows you to focus and clears your mind, but don’t rush. Banana Purple Punch Auto is a creeper strain and the full-on effect may creep up on you all at once when you least expect it.
After a couple of hits, the pleasant head high slowly turns into a powerful long-lasting sedative effect that feels like it's melting your whole body, relieving pain, stress, and symptoms associated with appetite loss while leaving you happy and relaxed. This nightcap strain definitely puts you to sleep, so take it easy.
Plant appearance
This variety is very easy to grow and without much effort will reveal its Indica lineage and show you what it’s capable of. Banana Purple Punch Auto can reach up to 120cm but grows thick and stout, developing a thick main cola with multiple short side branches that grow as thick as the main stem and can support the large-sized buds with ease.
Due to the Indica heritage, this plant has short internodal spacing which gives the impression that each individual branch is growing one massive bud. The beautiful dark lilac flowers contrast perfectly with the wide fan leaves that fade into a beautiful light green hue by the end of flowering.
Grow tips
Banana Purple Punch Auto grows extremely dense buds so remember to tie down the branches to improve airflow between the buds and increase light penetration, allowing buds to reach their maximum density while preventing mould and other pests.
Due to the bushy foliage, it’s recommended to defoliate gradually throughout the grow cycle, making your trimming session as easy and fast as possible. This plant doesn’t need much food to yield big so make sure to use good-quality nutrients, cover the basics, and it will reward you with big juicy buds.
Flavour
Banana Purple Punch Auto offers a fruity overload. On the inhale, expect a light earthy background that comes with touches of citrus and intense fresh strawberry and ripe banana flavours. And as you exhale, the fruity and citrusy flavours get even deeper, resulting in a strong sweet pineapple taste with that typical touch of fuel that makes the almost gummy-like flavour stand out even more.
