It won't be as much as in a full size setup or outdoor grow, but micro-grows can yield a lot as long as the lighting, soil, etc is good and they're taken care of good. So botom line is a YES, but that doesn't mean that you can't get great and a decent bit off a micro-grow.
You will be lucky to get anything. 6 plants in that sized area is too many. I'd do maybe 4 sog. 2 plants any other way. You only have about 1 square foot total in room if that.
Well the room is actually Alot larger than that its a closet but its a hydro setup and thats as big as the actaul console which holds the plants is..still not enuff room for 6? thanks alot yall
