Was looking for something better than yeast and sugar for co2-found this

Was looking for something better than yeast and sugar for co2 but don't want to spend too much. I have a small personal grow and I found this http://www.petsathome.com/shop/aquagro-co2-starter-kit-mark-2-(online-only)-79153?freeText=co2&msg=MSG_SEARCH_ONE_MATCHING_PRODUCT has any one tried any thing similar?

Maybe if you had a micro grow going in a cab, or just 1 plant. I couldn't imagine getting the continued exposure a closet or tent would need.

The CO2 Boost bucket does a great job little pricey but great job! You get fungas gnats with backing soda and vinegar...You can allways mist with sodium free tonic water! Work's awesome with smaller light's and lower temp's! Great CO2 for single plant's!
