Is it ok to interrupt darkness?

[Pass That Shit]

Yes you can interupt darkness for a very short period of time.....5 minutes or less......green incandesants work...but dont put the light to close because lumens will stop the production of the chemical the plant uses to induce flowering....my suggestion is dont mess with the plants till its wake up time. If you arent home during awake time I suggest making day time when your home. What ever it takes

I don't understand your comment about the lumens stopping the flowering process since they can be under lights for 24 hrs during veg? Are you referring to veg or flowering? Cause that's exactly what I did. I turned on some cool CFL's that I have in the room so I could see what I was doing in there.

Let me try to ask this question in a simpler form. Is there a problem with me turning the lights on and off as I please during veg?

Well, not really, but you should really be giving it a fixed light time, dont muck the plant around too much.

In flowering, however, you cannot interupt it at all, or the plant simply wont flower.

When the lights are on 12/12 the plant measures the un-interuppted darkness, which then releases a flowering hormone.

urghh u know what i hate about ur posts LIP? you're too 'brainiac' all the time.. loosen up a bit

OK so u want to know if interupted darkness will cause hermie? i'm not sure, but i do know that in the flowering stage it can cause yourp lants to revert back to vegatative which'll stuff up ur plants full potential and all that

according to my copy of Ed Frank's grow book, for light to affect the plant's cycle, it must be a light that is directly on the plant, and must light the entire plant ... a stray light catching a branch, etc. will have no affect (according to the book) ... personally, I leave my cabinet doors open when Im on the computer, sometimes for hours (its a couple feet away from me now) ... I enjoy the oxygen, and she likes my co2 ... never had a hermie, and my plants are typically without problems ... light, like temperature, and humidity, etc., all have ideal situations ... the plant will survive thru damned most anything, but to have healthy, productive plants, you want to try to stay near that ideal situation (but, no need to despair during minor fluctuations) ... :smokin:

as long as your not n the 12/12 cycle your good. If giving hrme 24hrs of light doesn't bother them then why would yu adding a little more from time to time hurt them? You're good just remember that when you're in 12/12 you need to paln your plant check and the lighting cycle around the normal times the sun rises and sets by you. It will be easier for you o eliminate light eposers this way.

should be totally fine in veg, might be an idea to knock it back in 1/2 hour steps over a week or two.

another note on a simmilar subject, i work a really wierd 12 hour shift pattern, somtimes days, somtimes nights, my plants are flowering.
but theres been occasion where i get home just as the lights are going out, not giving me enough time to perform some maintinence.

so what i did was kept the lights on an extra 1/2 hour, and knocked the timer back half hour, so instead of say 7pm-7am dark, it became 7:30pm-7:30pm.
not ideal, but no hermies yet!

if you really have to mess with the cycle for some reason, i think damage limitation is key, you want to be as little intrusive to the plants routine as you can.
