Light in Flower Room?

I was wondering what happens if light penetrates the flowering chamber? Is a little light ok? Does it have to be pitch black? I'm asking 'cause in reality when plants grow outdoors sometimes there is moon light. How much light is too much?

Its just optimum to have complete dark periods. In the wilderness the moon reflects an acceptable light by the plant that doesnt disrupt its natural flowering process. Indoors a lit light bulb or a leak coming from a cfl hardly replicates the slight hew of the moon. So i would seal up your flowering room if you can. Green light emmits the acceptable light for plants during the dark pd indoors, maybe it is relative to the same effect on the plant as the moon has, I really dont know....GL

the less light the better. Yes the moon shines...but its not near the intensity if a light bulb

Thanks for the reply. Well in my flowering room I sealed off like 99% of the light but there is a tiny little bit getting in from somewhere. I mean I can put my hand up in front of my face and barely see it. But its not pitch black, just mostly black lol.

the amount of light comming in is liken to very very subtle moonlight. Thats the only way I can describe it. On the mylar I see it's lit up just a bit, but its not reall reflecting to make light in the room. I dunno hard scenario to describe. As long as a little light getting in isnt going to screw thing sup im good to go.

If you need to get around in your room during the dark period you can use a flashlight with a green filter over your light or you can do what we did and purchase two green 13W cfl's and replace your light bulbs in the room with them. They give off enough green light that you can walk around and do what you have to do in the room. You definately want to have the LEAST amount of light pollution during the dark period. Your situation sounds alright, however, light pollution can cause serious problems. It can make a female that has already shown it's a female into a male or hermi. It confuses the plant if you mess with their lighting regimen too much. Stress them out you know. Good luck!

Yeah I won't be messing around in there at all. They'll be sleeping at night when I'm sleeping so I won't have to worry about interrupting them. Lights go off at 7pm and come back on again at 7am. I'll only open the flowering room while the lights are on so I won't disturb them.

Started flowering today, so, hoping for some girls! Not looking too good though, pre-flowers kinda looked like males but my first grow so I'll find out in a week I guess :)

I discovered a leak in my veg room that is barely making it into the flowering room. As stated I think I'm fine but I'll fix that up tommorrow and that should fix my problem even more.

I find it amazing that light can travel in wave or partical form. It's like tiny particles are "smart" and can find anyway into a room that is available. Amazing but the lil buggers need to stay out of my flowering room :mrgreen:

Good! Then you got to the bottom of it! Just a suggestion... as to your 12/12 hour regimen... Do you live in an area where you are going to get a wicked hot summer? If you are, like we are, in an area where there's been heat waves and generally hot and humid summers, I suggest you reverse your schedule and have your lights go OFF at 7am and ON at 7pm. This will have your lights on at night when it's cool and off during the day when it's the hottest. This will reduce heat stress dramatically. Best of Luck man! We just put our girls into flowering 9 days ago so we are almost at the same point. Keep me posted!

Yeah I am in a hot climate, the plants are indoors and it doesnt get too hot in there even in the 100+ and I did consider 7pm-7am cycle. I may go for that, I was thinking in terms of the most darkness in my schedule so i did lights out at night. Would it mess them up to switch the cycle now, only about 1.5 days in flower now anyway.

Check my grow journal I'll keep updates on there! You have one? I'd liek to check it out! Also, grats on the girls :)

You should make sure that as little light as possible gets in. During veg plants start to build up a chemical during photosynthesis. When the plant starts to flower the chemical reaches critical level if any light gets in brighter than the moon light it will destroy the chemical. If you want to look at your babies you can use a green light. Green is the only color on the spectrum that they don't use hence the plants are green so they don't use that spectrum. Good luck :)

plain and simple man .....try and avoid light during off time ...if you gots spots here n there ...patch em up with some duct tape.........:joint:

Also as long as you have a good light tight curtain usual no light gets in especially if you have a door as well.

haha good ole duct tape! See what I have is a "flap" which is the front door of my tent. It really won't close perfectly so I do duct tape it shut which helps. I have to fix the light leaking out of my veg room and should be 100% ok cause its pitch black in there without the veg lights (also in their own tent).

What I would like to do ideally is to build a frame for the front door where I can velcro the flap down to the door frame to get a good tight seal. When tiem permits and I'm not much of a carpenter, heh.

I'll never forget dennis leary said once "They say marijuana leads to other drugs. No it doesn't, it leads to fucking carpentry". So true!

Thanks! I don't think it would mess you up. I would get more opinions on that tho don't just take my word for it. But, I'm assuming that as long as you stay 12/12 you should be fine. I signed up for rollitup after I started this first grow so this time I don't have a journal. I'll send ya a few pics in your message box so i'm not changing your topic here on this thread! Best of luck. OH! You should try making homemade CO2. We just made a jug lastnight. You take an empty gallon jug and fill it halfway with distilled or ph balanced water, add about 5 - 6 cups of sugar, 2 tablespoons of Active Dry Yeast and put it all in the jug. Make sure you have a cap that fits and make a hole about the size of a pencil in the center. Put the cap back on the jug. Put the jug somewhere above your plants so it can "fall" down on them. CO2 is heavier than Oxygen so it needs to be above them. Turn off all your fans for about an hour when you do this. All you do is shake up the jug a few times a day and make sure your fans are all off when you do this. Change out the jug and make a new mixture every 2 weeks. This will give them the CO2 they need and help with heat stress.
