wow, you really dont understand what your talking about. I and others on here have done it for years, ive never ever had any problems with it and nor does any of the others i know. so how exactly are we doing wrong? because it goes against what you think of as correct? the shining the light on the face part is totally irrelevent.fuck that!!! strict 12/12 no light leaks. you can use green bulbs for maintenance now and again but thats it tbh if your obsessed with looking at your plants while their sleeping your doing all wrong in my opinion? how would you like somebody shining a stupid colour light in your face at 3am?
