    Let's say I subject a plant to 6 weeks of 12/12 light/darness, and then switch back to 3 weeks of 24h light. I understand that, at this point, the plant should keep flowering until it is done, despite the change. Has anyone done this?

    No, they will revert back to veg type growth. The buds as they are will ripen but will be stretched out with the newer growth coming out of the buds.

    There used to be a method of giving 24 hrs of light for a week to prolong flowering and see ~ 10% increase in weight. Really it is not worth the effort.

    After 6 weeks they most likely will not turn hermie but if you continually stressed them like that the chances increase.

    Ok,
    these babies are more on the sativa side of things. I read that it takes this type of plant up to 6 weeks to fully re-veg. I'm thinking if I cut the buds before I leave (my light source is a fixture), then leave the light just on, they'll probably keep flowering and then re-veg. BTW, this may sound stupid, but has anyone figured out how to attatch a timer to an in-the-ceiling light fixture?

    Yes, it's been tried. No, it doesn't work. Here's why:
    It takes about an hour and a half for the plant to "go to sleep" after "lights out", unless the last light recieved was in the "far red" end of the spectrum. With a six hour "night" cycle you are wasting 1/4 of the time while the plant is "changing over" to produce flowering hormones. I'd guess that adds up to about the equivelent of 3 or 4 extra hours of light (non dark, "sleep time") per day. So flowering doesn't work.
    This condition can be dealt with. The plant can be put to sleep immediately by making sure that "far red" light is the last thing they see at the end of thier light cycle. In other words, when the main lights go out, some far red light (I believe it's about 700 or 710 nm, as I recall) is still projected for a few minutes. That puts the plants to sleep pronto! It is even possible to flower at something like 13 1/2- 14 hrs. light / 10 - 10 1/2 hrs. dark, using this method - allowing more growth and more bud developement!

    By the way, if your lights are in a cieling fixture - what kind of lights are you using and where are your plants located?

    I've since talked to the guys at home depot, and they showed me how to a socket hook up, so I'll transfer the bulbs to a plug in timer set up.
    What I have:
    2X 85watt CFL, warm white = 12,000 (initial)lumens total
    1X 65 watt CFL, cool white = 4000
    2X 27 watt CFL, cool white = 3300
    1X 27 watt CFL, warm white = 1750

    I know these figures are low compared to HPS, but the lights are within 1 inch of the plants tips, so.............?
    Currently 2 weeks into flowering; will update.

    One of my clones is showing some pistils after 4 weeks of 24hr light. I'm attempting to veg the clones under a low wattage full-spectrum 'daylight' bulb while my main crop is flowering under a HPS. I guess it's just because the light isn't very bright, although it has been on 24/7. I cloned them before my main crop went on to flowering. Just thought I'd mention it....

    Ruderwhat? I have no idea what strain these are because they're from some unknown bagseed. The daylight bulb is supposed to be something like 30W but they say it's more like 90W because of the full spectrum. I have it real close to the clones and I thought it would be just enough to keep them alive until the previous crop had finished flowering and I could put them in to veg under my main lamp, but they're growing quite well, so I guess the bulb is bright enough. Strange about the flowering though. It's only a couple of pistils, but it's quite interesting. Maybe it is some genetic throwback. Jeezus man! I stripped some of my plants last night and had my first smoke in months with the finger hash. How I have survived a full day in work I do not know. I still feel really weird.

    Ruderalis is an autoflowering strain. Once it decides to go to flower it goes.

    If it is just a couple of flowers at the nodes then most likely those are just preflowers.

    Congrats on the finger hash!

    glad to see someone else on 24/12 or the like flowering . I've done same last two efforts.
    went 12/12 first wk. then 24/12 remaining 7 wks. Had good results, but wonder if I should have gone couple weeks extra to make loosing 2 night cycles eachweek of 24/12.

    This time working on 16/12 cycles works out even on the 7 day timers for 6 night times..

    If interested, 22/12 , 21/12 , 22/12 , 21/12, 22/12.also works on the 7 day timers ,saves getting up at odd hours to mantain light changes.

    let's say I've planted several seeds in one container, and they all boom. Is there any way to separate them with out removing all the dirt from the root ball?

    If they are just seedlings then I think that you could dig around the roots, if they are older and their roots are entangled then sorry but I'm not sure how to go about it.
