Plants won't flower!

[wisco61]

OK, so heres the deal. I have 2 plants (bagseed) I vegged for about 6 weeks, then put into 12/12 on Oct 1st. So its been 18 days and they haven't flowered at all. I had some light leaks at first, but the closet is 99% lightproof for the last 10 days or so. I have them in 3 gal pots with 6x26w cfl and 2x42w cfl on them for a total of 240 watts of CFL.

So I'm wondering if it is normal for plants to take this long to go into flower, or is something else going on?

Thanks in advance for any help/answers.

When a plant is entering the flowering phase and is interrupted with light leaks, it will revert back to vegetative growth. Switching back to the flowering phase will take up two two weeks. Feed half does of flowering ferts every now and then, and no more light leaks! Good luck!

candlelight ok?

NO light is EVER OK in your dark period.
Period.

Thanks for the info, I thought that was the case, but got some conflicting info from the FAQ here Text

How dark does the dark cycle need to be?
� � Consider that Cannabis can flower outdoors under the light of the full moon, so if your grow room is that dark, you should be OK. Having said that, it's best to make it as dark as possible. Plug all light leaks and be liberal with the black plastic.

Be sure to let your eyes adjust to the darkened room for at least two minutes before you try and identify how "truly dark" it is. If you can hold your hand out at arm's length and see your fingers, it is probably too bright. Light leaks are common triggers for hermaphroditism.

I believe you guys because that is what I had read other places, but the conflicting info in the FAQ confused me. So light leaks won't only stress your plant, they can prevent it from going into flower all together?

Also, what kind of N-P-K ratio should I look for in a flowering fert? Thanks again.

I have had great success with a closet that is about 97% light proof, so I'm going to have to disagree that it has to be 100%. Also different varieties may act differently (duh). I agree with the others that say your light leaks could have turned your plants back to the veg stage, but perhaps that's not what's happening. Maybe your plants will start budding tomorrow or the next day. Some varieties take awhile. If you need to do some work in your grow room at night, it won't hurt at all to have the lights on for 2 or 3 hours, just don't do it all the time. You can have 2 or 3 days of the wrong schedule without it reverting either way. Of course it is best to try and avoid this; 3 days just might be too much as well. If it does go back to veg at this point, it may be another month or so until you start seeing signs of buds. Also while it is doing all this reverting back and forth, they may appear to be dormant. Don't worry that will change if you just keep taking care of them.

since your using CFL's make sure they are the right light spectrum as well. You are going to need soft white for flowering. :thumbsup:

trynagethigh is kind of right about the kind of cfl needed for flowering. Though it's mostly in the correct color range, many people are saying what we want is warm white, or better yet very warm white.

Ultimately we want to look for a more specific color than what people are calling all manner of white. This is subjective and can lead to hibernating plants if you're not careful.

The numbers we are looking for are the Kelvin temperature scale, for measuring color of light, and you should not buy any bulb without checking this first. It's usually on the package. The color of light we want corresponds to peak chlorophyll activity of plants, therefore the most efficient colors for veg and bloom lights are 5500 or 6000 (not between) for vegetative growth, preferably 5500, and 2200 or 2700 (not between) for blooming, preferably 2200. The soft white are usually somewhere above 3000, which are not too good for our purposes. Whether youâ??re buying CFL or HID make sure you look for those numbers.

it shouldnt take a month two show flowers, you should deffinately see signs in the first week or two at the latest.

Opie youre right, should be warm...
