Wow, John! That's quite an increase.
Where are you going to keep all of them? Do you have a greenhouse?
with Rick. As he stated, when you bring them indoors, some may go dormant and lose all of their leaves. Remember this rule that was shared with me--no leaves, no water. There is no photosynthesis taking place. If you water your plants at this time, you will develop root rot, as the plant can not assimilate it. Others will go semi-dormant and retain their leaves. These will grow very slowly during the winter, due to decreased sunlight and heat, and will need very little water. If you provide sufficient light and heat as Doris does in her sunroom, they can continue growing and even bloom for you in the winter. I have 1 or 2 that do.
These plants are amazing, and I'm still learning about them. For the last 2 years, I kept 3 plants that went dormant on a plant stand sitting on my unused fireplace hearth in my den. Each year, in late January or early February, these plants would begin waking up. And I say Hey wait!! No, not yet! It's not time!" There doesn't appear to be an increase in the amount of light or heat in the room, nor are they sited near a window. But, they will unfailingly start to wake up and put out new leaves.
That's when I give them a little water and/or mist the leaves and move them to a brighter spot. Watch them closely and let them tell you how to treat/care for them. Congrats on your new collection/addiction/hobby and Happy Growing.
