plants wilting without humidity dome

I have 2 plants about 2 weeks old and whenever i take the humidity dome off for more than maybe 6-8 hours (if i leave it off at night) i will wake up to find they are all wilted up and dyieng I already lost 4 plants because of this but if i dont take the dome off they cant get co2 Right? temp 71 humidity 42. I got them in a jiffy dome and I just got the cheap soil with big sticks and shit in it although i removed all the chunks.

Brrrr too cold. How tall? what nutes?
PH of soil? I think though, that it's too cold for them, Had this happen to mine once. Add small heater underneath.
How low are lights?

i just have a 12 inch florescent about 4-5 inches from them enough room to fit the dome on and 2 cfls i think 60 and 150 or 100 I know its a biggun.
I have a oscillating fan blowing well above the plants so they don't get directly hit. I never tested the ph i havent purchased a tester yet. no nutes yet they are still very small they look like there maybe 5 days old. but the stims are hard should i restart and try warming it up cause i cant leave the dome on forever they will get too big

fan the plant directly. it helps build strength in the stems. if the stems are too weak when the plant begins to bud, it wont be able to support the weight . if it falls over and bends/breaks then it wont continue to grow properly. thereby decreasing your yield. make your fan blow at a low setting for a while the slowly increas it over the next couple weeks.

oh and you do not need a dome. just make sure the humidity is at about 50-60 % i fyou have a dome youll get upwards of 90% humidity which will kill the plant.

are these clones or rooted plants?

rooted plants, but as i stated i cant get any growth from them unless there in the humidity dome. can i place a bowl of water in the room to increase humidity? i want to do it without having to buy a humidifier. the seedling will even wilt after sprouting without the dome.
