With the dome you want to take care to "harden" the plants, that is, let them adjust to no dome over time. Give them 3 hours no doom for 2 days. Then up to 6 hours for a day or two and then they should be ready for 24 hours no dome.

Humidity and temp are fine although you don't want the humidity much higher as it creates conditions for mold to develop. Ideal temp range is 75 - 85. Higher temperatures mean more expiration so you plants may need watering more often. That said, most failures occur due to over watering rather than under watering.

Again, give that sticky a read. It details a lot of this stuff.
