You can also get a bit tech about it if you want. 180g of sugar will produce 44g of CO2. And 44g of will take up 22.4 dm3 or 22.4 litres of space. Once you have seen how long the yeast take to use the sugar you can ge a rough idea of the rate at which the co2 is being released. From that you can then work out how many containers you will need for your space to increase the co2 levels to that which you want. Just remeber that if the room is small and you have good extraction there is no point doing this just chuck one or 2 in. ;)

If you've got a small growbox, why do want CO2?

I thought the idea of CO2 was to get the plants as big as possible...

You'd probably be better off just focussing on the ventilation, and upping that if necessary. Good vents in a small growbox should provide all the CO2 you need, IMHO.

And you won't waste growspace by filling it with manky bottles...

Suger fermentation releases ~50% of its mass in CO2 as long as the alcohol level doesn't rise above the yeast strains %limit. So for your example 180g produces more like ~90g:-

sucrose has a molecular mass of 342 with 12 carbons, ferment it to roughly get 4 ethanols and 4 carbon dioxides. 4 CO2 have a mass of 176 so around 50% of the original mass.

only if u built the worst delivery system on earth....its not the froth ya want its the gas its releasing in those frothing bubbles.....if the reaction was exposed to the surrounding place yeah expect spray ....if it builds up and travels before escaping from a enclosed space then the gas itself will come out free of its frothy mess, and well smell is not the Cos either its ouderless :yinyang:

Any fermenting reaction creating Co2 will create a smell, home brews stink that fermentation happening.

But well to be honest i think ya wasting ya time, ya need be running multiple HPS lights to gain any benefit from raised CO2....higher cos benefits come into play with higher light levles found naturally at higher altitudes above sea level

when ya get to stage of needing extra C0s ya would be running say 6 400w HPS lights and price of a real Co2 delivery system with bottles of the stuff would be just another part ya growroom....if got wee drobe ya wasting ya i reckon
