It sure is.
I've had idiots try and tell me this piece of cannabis crap science chart was legitimate. There's a couple threads I'm not going to bother looking up and I don't remember what clowns were pushing this garbage but where the taproot comes out or this inaccurate chart.
It's all just stupid cannabis broscience and an embarrassment to the cannabis growing community that this stuff is even a topic of conversation. It's like saying the earth is flat.
