    Question trimming shade leaves???

    I have been reading apparently contradictory statements concerning trimmming the shade leaves on growing plants...I have a very small cabinet (2.5' x 3') and currently 3 plants in the mid flowering stage...they are pretty close in there, and I thought it wise, after consultation w/several online sources, to trim some shade leaves...Then I started reading some contradictions, from Ed Rosenthal el al, suggesting the trimming has a price, oftentimes too steep of a price, ie, disease, stunting or even hermaphroditism...Nothing I can do now, having trimmed 2 dozen or so shade leaves, but in the future, should I clip these huge shade leaves, or leave them be???

    I usually trim fan leaves cos im in the same boat as you with the space
    ive found it doesnt seem to harm the plants or not that i can see.
    i also trim alot of the leaves on the stalks it seems to produce alot flowers near where the leaf has been cut from.ED rosthensal did recommend it closet cultivator but it might only apply to certain set ups???????????
    you might be right with the hemaphrodite bit cos i did get it a lot from the first couple of generations after i started pruning but there not that frequent now there on the 6th set of clones it seems to be dying out.good luck

    Don't ever trim the shade leaves, they make the plants food so the bud can grow nice n big, and trimming may overstress the plant & turn it hermy.

    Dunno, I wouldn't prune or trim shade leaves, but topping the plant at the right time causes it to produce 2 colas at the top, not something I'd do if you got a lot of headspace in your grow room, but if you stealth growing in a small cupboard, or doing a scrog, topping is worth it, as I understand it (I'm a pretty novice grower myself, but I recon I've probably read a whole oxford english dictionarys worth of grow tips, it's often hard to tell the good advice from the bad, since a lot of authors seem to just recycle the work of earlier authors without actually testing themselves). Hopefully as time passes, more growers will post here, as the only real way to learn directly from folks who've tried it, experience beats 'book learnin' any day.

    Oh, sorry, and I don't mean to contradict you, bonbon, just adding my take on it (I'm in a bit of a bolshy mood, so I've probably forgotten my socail graces)

    Question

    greeting's boojum,I concur with you 100%,personal experience along with a little common sense are the definitive method's of learning.I happen to own quite a few book's from both of these renowned author's,(Rosenthal,Cervantes)and they advocate completely different method's,I tilt toward's Rosenthal's observation's,but i've gotten a good deal of info from the both of them,I guess that prove's that there are more than just two way's of doing thing's.

    Taking off sun leaves is not generally advised. Sun leaves are the energy source for plant growth. The exception is if a sun leaf can be removed to expose a growing shoot to direct light and IF plant nutrition is optimum.

    Wink solar panels

    hey peeples
    I see the shadeleaves as solar panels. may be the safe amount to trim is goverened by the light available. logic tells me that a plant must be able to survive natural predators attacking them. if trimming of leaves is dictated by amount of light maybe different hemisphere strains react differantly to pruning.
    I grow outdoor. I have found I can prune to make bushy plants but growth overall is definately retarded. Stress seems to govern hermaphoriditism 75%.The only safe way to take shadeleaves is till wait till budding occurs and remove yellow leaf- but by then its to late if your growing in ltd space. I prune very moderately from time to time seems to be okay. I'd suggest try strains with diff light requirements. Eventualy youll find a genetic match for the type of growing you require.
    Dont beleive everything you read. Best to experiance.

    I always think of the sun leaves as solar panels and if you cut the the big solar panels off then somthing has to slow down .
    I never done it coz i always had this thought and wouldn,t argue.
    Mind i,ve heard of this many times b4 in different books and posts.

    trim too many -no way for the plant to make it's food and too much stress they'll go hermy. trim too little - some of the buds wont develop as much as they could cuz of lack of sunlight.
    just trim a few of them so the lower buds get a little more sunlight but not too much.. lol

    The multiple colas thing is that if, while the plant is still vegging, you top off the growing tip of the plant, it will cause the plant to branch, and produce 2 growing tops. When you flower, each of the growing tops will form into a cola (group of buds), giving you two main colas instead of one, but they won't grow as big or fast, so it's more suited for growers with a limited growing height.

    i think i agree. ive trimmed plants mid flower and had some weird results compared to the same plants of a crop that havent been trimmed. slow growth and hermies, and some where seed pods appear at the junction of stems.

    The only time I ever trim off any of them really is during the flowering. But very moderately. Usually one leave per plant every few days, and just the ones that are shading the buds from good light.
    You are the deciding factor in your life!

    light, light, light, if light is geting to the bottem of your plant then your good , but i dont hesitate one second to grab the clippers durring flowering , the plants light needs decrease at an increasing rate and the need for the flower pedel to get the light this perduces nice big buds , sorround your plant in mylar or go down to home depo or wallmart , and pick up some florecent bulb mounts and put tubes that are made for groing ( not the floresent bulbs that usaliy go in them ) and put thease on the side of your plant to ad light , do not put them lower then half of the size of your plant tho , if you place them to low you will confuse your plant and stun it
    so what are we going to do tonight brain ?

    hey guys,i thought you was supposed to trim off the shade leaves when growing indoors to let the light in on the whole plant, and leave them on outdoors to help fight off fung. bugs and so on? have run across that a few places,

    if under the fan leaf you remove you have an equal amount of new growth surface area then I think it is hepfull to remove the older leaf

    Thinning:
    This really only applies to outdoor
    growers, but some indoor set-ups such as ScrOG,
    SOG and BOG may need to be thinned.
    Growers like to grow their plants in a
    uniform condition. That is - growers like all
    their plants to be the same height. That way we
    perfectly arrange our light so that it is too
    far away or close to the tops. If one plant is
    racy then we would have to adjust the light to
    suite that plant. This means that we may end up
    with light gaps like the following.
    -Distance from Plant A to light is 1 meter.
    -Distance from Plant B to light is 0.5 meters.
    -Distance from plant C to light is 8 inches.
    In this case you could imagine the plants
    in a slope shape in there grow environment.
    Obviously we are going to be wasting light, not
    to mention space on this set-up so we need to
    prevent this slope from happening. That is
    where thinning comes into play.
    The reason for the slope or curve is because
    291
    __________________________________________________ _______________________________________
    some plants might tend to be a bit racy. Some
    of the plants will try to grow quicker than
    others to try and receive more light. If this
    happens the racy plant will cause the smaller
    ones beside it to receive less light. To
    control racy plants we use a process called
    thinning.
    If you discover a few racy plants then just
    cut them down to the same level as the others
    (called pruning) or remove them all together.
    Once you have done this you will see all your
    plants growing nicely along at the same level.
    Now, do not throw away the cuttings from
    the thinning before you read the next line. You
    can clone these cuttings into new plants!
    By the time you have finished your thinning
    you will have an even grow area with some
    clones that you can use to grow more bud.
    Now the other thing to remember is that
    some people may tend to thin the other way
    round. That is - leaving the taller ones and
    remove the smaller ones. Again in Cannabis
    growing the taller plants are generally male
    and the smaller ones are female if you have
    started from seed. Do you want a garden full of
    possible males?
    During the thinning process you may want to
    292
    __________________________________________________ _______________________________________
    tackle some dead leaves or leaves that have
    some mould build up on them. Mould looks like a
    rust or fluff on the leaves and will most of
    the time spread to other parts of the plant. So
    why not cut these away too while you thin your
    grow area.
    Thinning your grow makes it look nicer and
    tidier and helps to improve your overall yield.

    The 'fan' leaves that we all refer to have a whole host of other names on other plants and in other circles. The name 'sun' leaves is also common. We're dealing with a flower here. One of the reasons that flowers produce their flowering shoots on the intererctions of leaves and stems is the internal structure of the plant. It places the most important part of the plant in the most convienient place to obtain its nutrition. Simplified even further you are dealing with a small solar collector. Every square inch of photosynthetic tissue you remove is either a loss of energy input, or something that the plant has to work harder to grow. Plants arent growing with the thought of getting you nice big buds. They are growing to produce enough viable seeds to continue it's species. One plant that produces 100 seeds has more than done it's job. Removing large sugar factories (the leaves) is one certain way of slowing down the plant. Pick up a biology books and look up common plants. No disrepect to anyone, but the only time that the plant isn't really using that much sunlight is once the large fan leaves start to yellow and drop the week before harvest or so. That isn't to let light in to the flowers, they are nearly if not totally mature. It's simply because they aren't needed anymore. If you look at any plant in nature, they do not grow unnecessary structures, it is a tremendous waste of energy. Nature is incredibly efficient, and even though most of us are going to very unnatural steps to produce our fine products, it's still a plant and follows those rules.
