I would put a cover over them to hold the humidity if they aren't already covered and give them lots of bright indirect sunlight. Get them adjusted to lower humidity slowly over several weeks by opening the cover for longer periods over that time. I can't give you a time table because I've always done my plants on their appearance. If they look like they are handling a change OK I increase it a little the next time. If they don't look like they are handling it well. I go back a couple steps and keep working back up gradually.
You will also have to keep an eye out for fungus. It can kill seedlings and small sprouts quickly. PFT sells two types of fungisides if you can't find any where you live. You can also try using a Q-tip or other cotton swab dipped in rubbing alcohol to wibe off the fungus.
When you water use only distilled, rain, or RO water. Tap water may be OK if it has a low mineral content, but if your not sure use rain water or store bought. Just be sure the store bought doesn't have minerals or anything else added for flavoring or to make it "healthier".
Once you've got them adjusted to the lower humidity to a point where you can uncover them for a while, then you can start adjusting them to more direct sunlight. They develope their coloring best when they have lots of direct sunlight.
