Fermenting in grow room

Im thinking about making my own wine first with store bought juice then eventually growing grapes and doing it right if i put the tanks that are fermenting in with my grow the wine would give of co2 and in turn feed the plants. Does anyone see any disadvantage to doing that?

Its great! I ferment beer and mead in a little area behind my grow room. I just use black/white poly to keep the light out, and it stays perfect tempature for fermenting. Your plants will love you for it!
Good luck with the Brew, and the Grow!
