Indimaniac,

I'm afraid you need to educate yourself in a few areas, one of them being humidity domes and training or weaning your plants off the humidity.

You can easily use the search tool here at cannabis.com - Placing holes in a dome isn't what your after. As the plant gets older you take the dome off for a few minutes at a time, multiple times per day, then for hours, then for several hours, then a day - This is done GRADUALLY.

Please read more on growing - It will greatly benefit you.

I DO NOT say this to be rude - But educating yourself will help you learn not to make mistakes like this, and be in a frantic search for help when something goes wrong - always better to be prepared.
