r/CannaBonsai

Hey everyone,

I've been growing for a few years now and know my way around a tent, living soil, nutrients and all that — but I've never touched the artistic/bonsai side of cannabis cultivation. Someone pointed me to this sub and I immediately fell in love with what you guys are doing here.

I've got this skull planter that I've been casually growing in, and honestly it sparked something. I want to deliberately shape a plant around it — make it a proper single cola grow, something that looks intentional and striking, not just "plant in a cool pot."

For me it's never been about yield. I grow for the fun of it, for quality, and for the aesthetics of the plant itself. Which is exactly why the idea of one single massive cola coming out of this skull is living rent free in my head right now.

Since I've never done a dedicated single cola grow before, I have a few questions for the people who have:

Side shoots — remove immediately or all at once? Do you pull every lateral branch as soon as it appears, or let the plant grow and then clean everything up right before the flip?

Is this actually stressful for the plant? Forcing all energy into one single point sounds brutal — or is a single cola grow actually more relaxed than heavy topping and training?

Pot size: If yield is completely irrelevant and I only care about quality and looks — is a 3L pot enough? Or does a plant always need a certain minimum root volume to reach its full potential, regardless of how much it yields?

And the thing I keep thinking about: Will that one bud actually hit different — insanely resinous, sticky, on another level — because 100% of the plant's flowering energy goes into one single point? Or does it not work that way and quality would be the same with multi-cola? In my head this HAS to become the ultimate mega bud haha

Would love to hear from people who've done this intentionally. Any advice on shaping around the skull container is also very welcome.

Almost time to repot her. I'm pretty scared to do it tho.

Hi everyone,

English is not my native language, so sorry if I make mistakes.

I need some help with my bonsai (Groot). Recently, I noticed some white fluffy stuff on the new shoots, and I’m wondering if it could be powdery mildew (oidium) or something else.

Has anyone seen this before or knows what it might be? Any advice on how to treat it would be really appreciated.

I’ll add a few cool photos of its progress at the end so you can see the plant better.

Thanks a lot!
