Bambusa indoors?

[BeyondTheGarden]

I acquired 3 different species of Bambusa from ebay; I am very pleased with them as they weren't cheap but the size of the root ball and foliage is bigger than expected.  

B multiplex Alphonse Karr, B malingensis, and B oldhamii.  I think they are all close to the edge of their growing zone here in zone 8A, and if oldhamii doesnt function as a dieback perennial it will probably die altogether.  

I am trying to start a lot of things indoors over the course of the winter to get a head-start before planting out this coming spring.  I have never grown bamboo indoors.   Is this familiar to anyone?  Will they do poorly due to deprivation of heat and light?  I know bamboo are also firmly rooted in their natural clock (I think there's a technical term  for this), all that I have grown only throw a new flush of growth one time during spring.  Would growing indoors disturb this process?  If I don't bring them indoors, they'll sit out in my garage where temps stay above freezing but are much cooler than indoors.  40's-60's depending on the weather.

The Multiplex should have no problems down below freezing, even into the upper teens, as multiplex are some of the most cold hardy clumpers.

Regardless, you can certainly grow them indoors as long as they get light and occasional watering.  I know at one point the Polynesian Resort at WDW at a ton of Golden Hawaiian growing in their lobby.

Those are some good sized divisions....
