Das war ein Fest! Absolute Empfehlung - für mich bislang einer der einfachsten und besten Grows. Die Buds sind schön kompakt, haben eine sehr gute und gleichmäßige Größe und sie schmecken richtig lecker nach einer Mischung von Orangen, Minze und Zitronenschale.

I am grateful to have Bubble Gum in my collection.
In general, I prefer growing BG outdoors rather than under LEDs because the smell and taste is stronger and more versatile to me and the BG is a very robust and resilient cultivar. Its not the strongest but a nice daytime smoke for me.

In about two weeks, I’ll be sharing my full review of this fantastic strain after giving it enough time to cure properly. I’ll cover the entire grow from start to finish, what went well, what could have been improved, and, most importantly, my final thoughts on its aroma, flavor, effects, and overall experience. Stay tuned!

Hi, thanks for following me on your other account: "Serious Seeds official profile". Is it you? Why two accounts?

Hey Removed, see answer:
👉There is one big difference between auto's and 'normal' plants: the vegetative phase is fixed with auto's. They will always start to flower when they reach adulthood, after 3/4 weeks. This means that individual plants do not differ much in size (how much light / food they get in their vegetative stage is the biggest factor to determine end height). Light dependent plants will only flower when you, the grower, decides to start with 12/12. Therefore their sizes can differ enormously, and their yields too. Which means that we can give a sort of expected yield per individual autoflowering plant, but not with light dependent plants which is indicated in gr/m2. Often the latter are cloned to fill a grow area with small identical plants, which is impossible to do with auto's.
Hope this helps 👍

Hey, guys! Your Autoflowering White Russian #1 mentioned to be fine on seedfinder so I want to try it, but I'm confused with your description, cuz 10-20 grams per plant is nonsense today. Is it a part of history now, or you continue to develop your auto?
