Thanks Kraven. Thought i would make the most of the sunshine this season. I have grown a bubble bomb outdoors before and it turned out great. I plant them around the start of summer because i don't want it to be a massive tree and cause undue attention. Where i live we get long hot summers so it's very easy to grow very large plants outdoors as long as they are watered often because it rarely rains. We don't get snow during winter but it does rain a fair bit.
