I think that indoors isn't such a good idea. I have some in a 55 gallon poly drum cut in half. I made a cage of 6' welded fabric fence with wire going between the two halves at the top.
Last year, I only filled the drums about half way and the plants were very unhappy (they barely grew to the top of the fencing and didn't produce many cones). This year I filled the pots w/soil. With the rain & sun we've had here in the bay area, my Magnums are about 3' tall. I hope to get them trained to go horizontal when they get to the top.
Don't know what I'll do if we get a late frost.
Last year in half wine barrels my centennial cascade and Willamette grew about 8' vertical then another 8' horizontal. Off three barrels, each with four ryzomes, I picked about ten gallons. Dried on a window screen on a box fan laid flat. I brewed two pale ales and had about 8 oz left over. About a pound total. When you run them horizontally they need help wrapping around the twine. I bought some 12' cedar and building trellis this year.
Even in my 27" pots my hops make the ~14ft run up to my deck railing without a problem (and would probably keep going if they could). The issue is keeping up on the water and nutrient needs for such a fast-growing plant in a container.
