Purple Wreck outside can get pretty big but from what I have read/seen they don't produce much more then 400-450 gr/m2. I googled smart pots and they just seem like a different style of a hempy bucket to me. Post a link to the product your looking at it may help. Oh and my most recent grow log is of Purple Wreck and there are a few others on here that roll with that strain.:hippy:
