So I got one of these CO2 canisters for my plants. Reading the instructions, it says use white table sugar, use no substitutes. Trouble is, I don't keep white table sugar in the house, I only use natural granulated cane sugar. Will it really make that much difference if I use this? I'd imagine I'd need to use a bit more than I would of white sugar... perhaps that's why they say don't use substitutes? I can always get some white sugar but that means waiting at least a week before I can set this up.
