As colourful in flavour as its name suggests, the Rainbow Cake strain brings together a citrusy punch on the inhale with rich kush undertones and a lingering sweet finish. It’s a layered, dessert-like flavour profile that rewards connoisseurs with complexity and balance. The aroma is just as enticing — expect waves of fruit, cream, and earthy base notes with a light diesel finish.

Eric Etheridge –
This lady was absolutely fantastic to grow. I rooted her right in a 10 gal filled with living soil and she took over the rest. Beautifully structured and hella frosty as well! 77 days from sprout to harvest with the Terp profile of creamy vanilla cake and a sweet mixed berry with just a touch of spicy gas🤤 She should be in everyone’s garden in my opinion! Awesome stuff🤗
