the dragon fruit plants are so very sun hungry.. they only thrive in lots of sun... mine do OK inside in the winter ... but it's thin stringy growth .. figureing if it can only grow up some there will be some more sun for it... not the case inside... as it goes outside in the spring... these fill out and there's some real growth with it... outside I have to keep rotating mine around... as in full sun it really only develops on the sunny side...
