That root system is absolutely insane! She's clearly been loving her environment. I'm really curious about what medium you're using, it looks so rich. I'd love if you could check out my diaries and give me some advice on my own progress!
@wolfvb, Hi, thanks first of all. My medium was BioBizz Light Mix, fed the first two-thirds with Canna and the last third with BioBizz. I have to say the Canna root fertilizer is really great and completely organic. I looked at your diaries; you could use larger pots. Mine was in 15L and try to make sure the main root could grow straight down without any solid pieces getting in the way.
@Headbang, yeah I'm thinking to moving to fabric pots for my next grows, been experimenting with it with my current grow and the pineapple Express really love it
