I have heard of someone doing that with grape koolaid and it turned the plant purple, never heard how it tasted, also I only HEARD that never saw, but sugar is good for your plants, esp. molasses and sugar cane, but i don't know about the dyes and other Artificial Flavors
What? Really?
That seems sort of Ghetto to me, but hey has anyone actually tried it?
Speaking of flavoring weed. Since soda is carbonated shouldn't it have Co2? But then again it may be too acidic? I don't know, just a thought.
I have used plain carbonated water (no sodium) on a plant for a one week experiment. And the plant experienced a quick growth spurt, but the leaves became very tough and dark.
