Good effort so far, but that bubbler is going to stimulate so much growth for the plant that is going to really want to grow, but that light will not give enough photo synthesis IMO to give it a fare chance to do what it needs to do and what you are going to want it to. The plant is going to want allot of light to produce the root structure in that bubbler as well as allot of foliage. I don't want to sound pessimistic, but you know environment plays so much. Hope it works in spite of my observations, but someone else can maybe give their opinion.
