I've been growing Bubblegum for the last few years. It grows easily indoors and outdoors. Growing outdoors it will mature when the daylight dictates. Whether I start indoors in April and move them outdoors in May or plant directly outdoors on July first they will mature around the end of October (45ΒΊ latitude). They will bear up to frost very well and show purple leaves and flowers.

Indoors they can be grown to harvest in 12-16 weeks, depending on veging time.
They respond very well to cropping and ground training by bending (breaking) the stems over, keeping the plants within 12" of the ground. I do this to hide the plants and it has been working out well. I have had plants stolen from the same general location, so I'm pretty sure the site has been scoped out by bandits.
It is a strong, mostly indica buzz. Personally, it does have some anxiety if I smoke a lot. It tastes pretty mild and smells fruity sweet/fresh green but not at all like "hay". It has lots of resin/trychomes and fat leaves.
Average yield for a plant in a 6 gallon container is three ounces of dry-cured bud.

The outdoor plants have lower yield per plant due to the training.
