Does the amount of humidity affect the growth of tulip plants?

OMG!! i did this project for science fair!! more specifically, my question thing was "how cna a simulated weather condition affect the growth of a plant?" i used a bulb plant, the amyrillis minerva (no tulips in home depot). the results were waht i'd expected. bulb #1 was put in the freezer. i watered it according to the snowfal of my hometown, edison, new jersey because snow melts and stuff. bulb #2 was left at room temperature and watered according to when the soil was dry at the surface, about once a week because my project was done in decmber. there's limited humidity in my house. bulb #3 was put in the laundry room. it gets really warm in there cuz of the washer and dryer's constant use. i calculated the humidity and found it to be only 3%. the results? bulb #1 never bloomed until after i took it out the freezer and spring came. (i live in the panhandle) this took about two months bulb #2 also bloomed in spring, only slightly earlier than #1. i kept it inside my house. bulb # 3 bloomed before its sisters. i saw its flower in january.
