I only planted mine on Thursday and I already have a bine that's 2-3 inches long and little buds shooting up all over the place. I have a feeling once they wake up out of hibernation, they explode. Not sure how well they would do inside for two months, they might get too big for you. But there is really no harm in trying
I have a question related to this regarding when to transplant my plants outside?
I ordered two rhizomes when they arrived in the mail, becuase that's what the instructions recommended. One looked like it had a lot of a mold-like substance on it and not surprisingly, hasn't sprouted. The other has sprouted is already going gangbusters... growing an inch or more per day lately. I live in a relatively cold climate in Calgary, and general guidlines for the last frost is about the 3rd week in May.
I'm a long way from that date but I'm worried I can't keep it inside much longer at these growth rates.
Any ideas?
