I re-cut the stems and dipped them in cloning powder

. 2 of 4 are rooted. I did my own little test which is to slightly pull up on the plant after a few days. The two that ended up showing roots were locked in the soil and the other 2 that I tested to day came right up. So I had to recut those 2 and ill leave the dome on for a few days now. Is it ok if there domes have a little air hole ? Or should there be no air at all the first few days ?
