will filament bulbs affect growth?

my plants are currently on 12/12 light cycle, but i was wondering if having a filament bulb on while they are sleeping affect them?

thanks!

please help me!.. their just normal household filament bulbs..

Great question!..

Not knowing the real details about phytochemicals and hormones and such I dont have an 'educated' response but here's my 2 cents...

A 60w bulb puts out 800 lumens..

And to quote Wikipedia on light intensity and inverse square law.. "The intensity (or illuminance or irradiance) of light or other linear waves radiating from a point source (energy per unit of area perpendicular to the source) is inversely proportional to the square of the distance from the source; so an object (of the same size) twice as far away, receives only one-quarter the energy (in the same time period)."

That being said if your incandescent light is 10ft away, its going to have almost no lumens compared to your grow light.. Will this affect hormones and phytochemicals? I have NO idea lol... But If you HAVE to have this light on, I really dont think its going to matter

wickedy wack
thanks!

Any one else have any other views on this?

Well I did some research after I posted here and I think I'm going to retract my statement.... There's a good chance a bulb in the room could throw you off. Take it for what its worth /shrug

i think ill shrug for now lol.. thanks

You need to have them in COMPLETE darkness, with any light getting to the plants it stresses them a lot and you have a good chance of them turning hermi and popping out seeds...You don't want seeds in your bud now do you?
