If you can cope with it possibly turning into something that resembles a tree, go for a pure sativa, like Durban Poison. You can only grow it really if its relatively dry in September/October, as thats when the harvest time is and you dont want budrot setting in at all. If youre planning to grow a pure sativa indoors, then make sure you have at LEAST 10,000 lumens of light and at LEAST 5 foot of space (upwards). This isnt 5 feet between the floor and ceiling, its 5 feet between the lamp and the floor.
You mentioned that Bubblegum is suited more for indoors... are you planning on growing outdoors then? And I hope its next year, because youre way too late to be doing it now! Sorry if you already knew that, I just have to check
Oh, and dont pay attention on websites when it says 'suited for indoor growing'. Someone on everyonedoesit.com grew two Durban Poisons outdoors (in the UK), and they got 7 DRIED ounces off each plant. And this is for a plant which apparently does better indoors than outdoors.
