Thanks man I have another two hidden out in my cupboard they're kind of stepped in progression the other two have acted like photo plants along with my northern auto and they're massive I don't think they've finished stretching yet. I'm getting some trays for each plant to sit in and feed of their runoff, I might as well put them roots to use haha. But I think the pots are definitely to blame because they are fabric they hold water attracting the roots to keep growing when they reach the edge whereas in them smart pots the soil or coco round the edge of the pot dries up quicker forcing the roots to ball up that's my theory anyway so I'm definitely buying some smart pots soon I still have two cherry bomb seeds left so I'll get some for them and do a comparison. Thanks for stopping by man
