My HID bulb failed sometime today during my 12/12 cycle, the plants have been in flowering for just over two weeks and I know the bulb was on for at least 4 hours, went on at 8 left for work at 12, got home at 8 just as it was supposed to be going off, made it in the door at 7.55 and saw that the light was not on in the room, checked the bulb and failure for sure and it was cool to the touch, could tell it had not been on for at least 2 hours, possibly as many as 6, so will they be ok, getting a new bulb in the morning and set my cycle for 11-11 tomorrow as the shop opens at 10, any help tonight would be awesome, hoping you guys on the west coast are still up

Re: Lighting ?
you should be fine, put any light you can find on them if the light is supposed to be on now, yes, we're still up!!

Re: Lighting ?
nope, would have went off like 5 minutes after I walked in the door, should I push back the light going off tomorrow since the HID will be coming on at 11 instead of 8, or just keep the tent open and let natural light in for the 3 hours till the HID comes on and still have that go off at 8pm instead of 11

Re: Lighting ?
What matters during flowering is actually darkness, not daylight. Let me explain.
See, the plants produce a hormone (can't remember the name at this time) which builds up over night (lights off) and gets destroyed upon exposure to light. This hormone is responsible for inducing flowering, so when you have the plants under 18/6 the hormone doesn't have enough time to build up and trigger flowering and that's why you can keep a plant for a very long time vegetating.
When you change the schedule to 12/12 then the hormone has time to build up and trigger flowering, so a longer dark period does not interrupt or affect flowering in any way, the only down side is that the plant won't grow or develop much during those X amount of hours because, obviously and as we all know, it uses light for photosynthesis.
So in short, rest easy and just wait for the replacement to arrive. You can still use other light sources in the meantime so the plant can get at least some photosynthesis going. Use a few CFLs if you have them around.
Hope this helps.
Good luck and happy growing!!

Re: Lighting ?
That does help a lot, and yeah, don't have anything suitable around but literally just got this all set up about 4 months ago and the Digilux bulbs carry a 1 year warranty and I'm know my local grow shop owner well, should just be a simple swap in the morning, thanks for allowing me to sleep better tonight

Re: Lighting ?
No worries, its always good to be able to help a fellow grower.
What kind of HID are you using? HPS, MH, etc. As far as I know they're supposed to fail after about six months of use (or so I've read/heard). Mine (400w HPS) has been running 12hrs a day for about 5 months and I got a replacement about a week ago so I'm ready if it fails (hoping it doesn't!). So if yours failed @ 4 months it MIGHT be within the acceptable lifetime or maybe it was used or maybe some equipment is malfunctioning, don't really know so I can only speculate.
This is my first time using this kind of light so maybe someone who has been growing for years can produce a more accurate answer regarding the lifetime of an HID bulb.
Good luck!

Re: Lighting ?
K well I just looked at my reciept from the grow store and I bought it all on 6/7/13, I think a month and a week is a little short, keep in mind I'm only in week two of flower so really the HPS bulb only has two weeks of use, he better just replace it for me or I'll be pissed

Re: Lighting ?
whilst the above post does indeed contain some facts, it gives no consideration whatsoever to light shocks, which very easily and commonly produce a hermie trait in a regular plant.
in the situation of a bulb failure, one should do whatever is possible to convince the plant everything is the same and ok, that the sun hasnt suddenly exploded and plunged the world into darkness.
you dont need super powered lights either, a couple of 20 watt house cfls will help convince the plant its daytime (albeit a cloudy day).
also consider giving the plant anti shock treatments to help reduce the risk of hermie and buds full of seeds that few people would want to purchase.
take a look at blue planet nutrients, one of our sponsors and a great alchemist not only runs the whole show, but is also a member of this community and actively helps growers using his products =)

Re: Lighting ?
While Giga may have a point with the light shock, I think this may apply for a longer and more confusing and inconsistent light schedules (on for 3 hours, off for one, on for 2 off for 4, etc), but a single instance of 24-30 hours without light I don't believe is going to matter. An anti shock treatment I believe to be an overkill.
We have to remember that always when it comes to plants less is more (except with light, they can always use more light), but using too many additives is never a real good idea unless absolutely necessary, which I don't believe this case to be.
I did suggest the use of another light source in the meantime.

Re: Lighting ?
appologies for the delay, had to dash out unexpectedly.
the products i had in mind from the availible selection were the cold pressed liquid seaweed and the vita blue vitamin supplements. whilst the owner does not try to specifically push them as anti shock, if you study the effects and benefits of the constituent vitamins, minerals and hormones provided in those 2 items you will see that they are incredibly useful and powerful in stimulating the plant to grow and to be strong and resist illnesses e.t.c
these two items are specifically designed to be acompiniments to a general npk style feeding and will go with almost any multipart feeding schedule. i would also like to say that these two items are universally beneficial to all forms of growing not just our specialist plant plants.
i use liquid seeweed in my standard compost heaps and i love bpn products so much that i have them shipped to me in the uk from america when i use 'pro' nutes.
Rodrigo is totally correct that a single incident of light stress will be unlikely to cause a hermie, but it is possible and the odds increase with every new light change.
a plant in the prime of flowering is not going to be happy tho with a sudden unexpected 30 hours of darkness, just saying is all
edit:gotta be honest my friend im finding it hard to find anything in that revive that isnt in most good feeds anyway.
i know a lot, but when it comes to the really deep understanding of the magic of plant foods and additives and what can do what you should really talk to the owner of one of these companies. i cant talk for advanced nutrients but i know that the owner of BPN is riight here in the community with us =)
he would better be able to explain why and if his products can help a plant stay strong and vital and resistant to stresses.
