Simple question: Will house bulbs interrupt the dark period?

The way that I understand it is that UV light from the sun or from a grow bulb inhibits or destroys the flowering hormone that's always present, and once the plant can no longer absorb this radiation(at night) the hormones continue and the plant gets farther along in flowering. Since normal house bulbs have no UV emission the plants shouldn't be able to even detect it, and flowering should go as normal, correct?


one of these:

no, not correct. the color spectrum is what the plant sees and pretty much any color other that green will cause problems.

I grew my entire first harvest using those bulbs, so the answer is those bulbs are picked up by the plant.

what wattage were they?

^ doesnt matter the wattage..... if light is let in your during the dark period, and it is not green, your signing yourself up for trouble

I think it was the ones that said 100w but only uses 60w of energy or something like that. It was about 3 years ago so i am not sure what they were exactly.

100w equivalent bulbs are 23-26 actual watts a piece

One of those will fuck up your flower.

yes yes it will, u want 100% darkness or as close to it.

no light period during lights out. You might get away with a few mistakes during veg but leave any light besides a green spectrum cfl on during lights out in flower and you risk turning your crop hermie.

if you introduce light during a dark period you are just begging for a hermie....is that what you want in your closet a hermie??? That's sick man lol happy growing

I had a friend who was running an Air conditioner with a bunch of LED lights on the dispaly. We attribute the red and blue LEDs to causing some seeding in his crop.

how does artificial light interrupt the flowering cycle? isnt there a difference between sunlight, grow bulbs and household lightbulbs?

i don't have my resource books any longer but from what i remember any flash of light, for even a second, that is in the red spectrum (incandescent) will flip a chemical switch in the plant that can't be undone. you delay your harvest by a few weeks, mb a little less.

My common sense tells me that the Suns light is good considering that outdoor plants receive actual Sunlight so, hw would that be bad for plants AND any light source that interrupts dark-period would not be good - come on people, common-sense!

Let me take that back a bit because now I'm thinking of how the stars(in the sky) give off light@night s0, if your in your room and your grow is in your closet, having your computer monitor on shouldn't really do any damage - besides, the closet is shut.....

Im living proof that light, even just a little, can harm a grow.... i just lost my last two grows to seeds from light leakage.... i never had this problem before but now, two grows - only thing i can think of is the light cycle. I'm so heartbroken i just ordered a grow tent to try and fix the problem once and for all - wish me luck

The moon puts off light.. Plants flower fine with light in dark,, in Nature.. not in an indoor grow. if your planst get some filtered light every now and then.. its not a big deal ( to me,, others will cry HERMI).. If you turn on your lights a 2pm ( dark cycle) for 5 min at the same time each day,, your plants will stop flowering. Light does not bend.. so if you have a good tent.. you can turn you light on all day long.. the light wont enter, Not the same as seeing "light leakes" at night

I disagree.. you had a male in contact, Hermi or Intersex.. light will not make a plant seed,.. I could only wish that was true.. breeding would be so much easier. Hell all outdoor pot would always be seed.. any outdoor growers have any say in this?

Maybe youre right... i just chopped my plants. In the chop process, i found a hermie... Now why this plant was hermie is the question. Did the light stress cause it? Was it genetic? I dont know - just upset
