BlaKX Description
Guava Runtz Auto is a next-generation autoflowering strain developed from two proven winners.
On one side, we have our Guava Auto RF3: a fully stabilized line and winner of the last Autoflower World Cup. On the other side, Mango Runtz (Mephisto Genetics): a multi-award-winning hybrid known for its terpene quality and very compact growth.
The goal of this cross was to combine top performance and terpene expression in a single F1 hybrid. Initial tests show strong hybrid vigor, combining the handy structure of Mango Runtz with the added strength, freshness, and growth energy of Guava RF3.
The terpene profile is intense and present, with notes of tropical fruits and sweet candies, as well as a deep, complex aroma that unfolds beautifully from the bloom to the finished product, providing an appealing look. In terms of appearance, the line shows two main phenotypes. Both exhibit very similar terpene profiles: one tends toward a deep black coloration, while the other remains greener and develops dark tones towards the end of the cycle. Both are vigorous, form dense flower clusters, and display a uniform structure within the population.
Guava Runtz Auto was developed for breeders looking to work with a strain that stands at the forefront of modern autoflower breeding, combining stability, terpene depth, and performance in one line.

BlaKX Incredible Growmies!
After 21 days, the Guava Runtz Auto đ
has broken the 60cm mark!
It handles the heat and high humidity very well.
The branching is developing splendidly, just like the plant overall, setting standards.

BlaKX CRISIS! While watering yesterday, I spotted a thick, almost drooping flower calyx out of the corner of my eye, but when I removed it, pollen came out, I have to say. Since I didn't look closely and crushed the thing right under water. I examined it thoroughly again and found nothing! I'm pushing through and checking them very carefully.

BlaKX Week 7 is over and the Guava Runtz Auto đ has long buds with clear Sativa dominance! It will definitely take 10 weeks until it's ready for harvest! All in all, no pollen sacs discovered!

BlaKX Greetings Growmies, late to the 8th week!
The size of the buds is overwhelming and the frost is looking good.
The trichomes will still need about 10 days.

BlaKX End of week 9, Growmies!
Finally, I remembered to get a measuring tape to check the size, and look at that, I wasn't mistaken!
Unfortunately, I can't get the heat down in the tent anymore, and I will harvest at 10 weeks before mold or something similar happens to me.

BlaKX Leave them for 10 days longer and reduce the nutrients so that they will use up their reserves! The buds are firm and compact, emitting an intense sweet smell with an appealing unknown scent!
