At this stage, air flow is your greatest chance of reducing the humidity now that your plants are flowering. Single use absorbent gels or crystals will do nothing.
Extraction, extraction, extraction is the easiest method and probably best for your situation. Plenty of air movement and air replenishment.
Atmospheric humidity should not be a major problem, stale, still, non moving air is your enemy.
I wish you all the best with your first try at growing this remarkable plant!
