Fuck that shit,,, what kinda jackass dose that to somone elses plants,, id lock down those plants, anyway possible,, paddlocks if you have zips, and bolts on doors and that with padlock stops.
If he keeps going in boobie trap the entrance,, I take it a pungie pit isnt practical.
Think about it as in he has done somthing you have asked him not to. Has he asked you not to do somthing, cause if so he's claerly a dick.
And distruping the light period,, in my view the plants would be better of if he hadnt to as if he had, regaurdless of weather the plants are effected or not.
Also with taking a bud, that bud woulda bin better if he hadn't so that clearly dose have an effect on the bud and plants..
What kinda ass is your room mate. Id say he owes you money for that bud, cause they woulda been so much better if left on the plant..
Id find a new room, or new room mate...
Take it easy.
