    Question

    Will keeping the flourescents on all the time have any side effects on growth? Will it not flower correctly ? will it speed up the growth of the plant? or do you think that it will kill the plants? I am considering this?

    Hello,
    Bad idea, first off, theres the cycle of photosynthesis, where plants make food for themsleves.To keep lights on 24/7, means that they would be making energy all day, they do this by taking in sunlight, water and C02, and making a form of sugar, glucose. So, with lights on all day, the calvin cycle wouldn't come into play. The calvin cycle, or dark cycle, is where at night the plant replenishes itself after a day of making food by eating it. Now, if it kept making, and making all this food, and not having a dark cycle to eat it, the plant would exhaust itself and die, because of no food. So, get more lights, and a heathy photoperiod.

    I agree with Kevin, a 14 hour photoperiod is best with 17 hours being the maximum photoperiod.

    Has anyone actually tried this? I ask because there ARE plants that can be grown this way.

    Only seedlings,and arctic plants can be grown this way. There have been studys on this and it has been proven fatal to most plants.
    And even with seedlings anything over 18 hours will not be utelised and is therefore wasted.

    Actually theres a bit more than acrtic plants that follow the C4 photosythetic pathway. Corn, Soy, and Sugar Cane to name a few, all of these can be grown under increased photoperiods.
    Here is a nice site regarding Photosynthesis, lots of info!

    There are a few pings and sundews up in alaska... Pinguicula vulgaris and Drosera rotundifolia... I bet they would do well with a 23 hour photoperiod
