Looking good keep it growing.
I have attached a pic of what i do for my cheapass co2. This way it stops the smell and foam getting into your grow room, the other benefit is you can see the co2 bubbling out of the second tub and that way you know when it is working. After a few days co2 production will die off a bit, just shake the pop bottle and it should get better. Once this stops working then change the sugar/yeast mix.
