wtf is FIM

K Ive read a shit load of threads about FIM prunning and amist all the in depth descriptions i dont get it i need a visual to understand this type of prunning. can anyone show a chart or close up before and after of doing it...i want to try but i dont get it.

i FIMMED a plant once then tied down the side shoots and man oh man was that shit bushy to bad it was a male though
 
nice i dont think that is ideal for me i want a tall girl about 5foot 6 inches any thoughts on how to trim it i topped it yesterday....i want to get a big yield with big colas...any ideas im gonna finish in a five gallon bucket or maybe a little bigger im goin for somthin like this

FIM is simply a technique whereby you take a sharp razor and slice off the growing tip in order to produce more more shoots and allow lower growth to catch up, thus causing your plant to become bushier.

If you want big yields, adding more growing shoots(more shoots=more large colas:wink:) can only help. And if you want big plants, then just veg them longer.

Hope this helps,

From the Glossary in my sig:

Unofficial Glossary for New Growers said:
FIM or fimmed - Stands for 'Fuck, I missed'. Refers to attempting to cut the growth shoot of a plant so that it grows into multiple branches instead of one. The phrase comes from how easy it is to miss the tiny growth shoot.

1 plant i done a mulit FIM on every branch i could i did FIM !!!


50-55 days after @ chop

ifn memory serves my correct i pulled 2oz dry from 1 gal grow bag :) :rasta:

during veg you can FIM several times to keep the plant shorter but each time FIM is done your adding more branchs and growth shoots. after FIM has been done you'll notice 1-2 sets of leaves grow out funky no worries the leaf will grow prim and proper ya cut 1-3 sets of leaves during the FIM :)

after fim'ing, topping, and leaving strains go on their own i came to the conclusion that topping and fim'ing doesn't mean more buds bigger yields...alot of it depends on the strain and style of grow...some strains need that big untopped main dominant cola to yield huge others don't....some strains just produce many more smaller buds when topped where if you left it alone it would of yielded way better buds...but then some strains respond well and grow many thick solid nuggets that end up yielding more then a few big tops...u gotta experiment with your strains to see what they like and don't like to improve yields.

Follows is a link to cannabis botany..

http://www.mellowgold.com/grow/mjbotany-removed/

In it is the more technical description of fimming and why it works.....


A botanist however is not likely to call something...

fuck I missed..... lol....


This is in chapter 2.... see the second paragaph....


Pruning

Pruning techniques are commonly used by Cannabis cultivators to limit the size of their plants and promote branching. Several techniques are available, and each has its advantages and drawbacks. The most common method is meristem pruning or stem tip removal. In this case the growing tip of the main stalk or a limb is removed at approximately the final length desired for the stalk or limb. Below the point of removal, the next pair of axial growing tips begins to elongate and form two new limbs. The growth energy of one stem is now divided into two, and the diffusion of growth energy results in a shorter plant which spreads horizontally.

Auxin produced in the tip meristem travels down the stem and inhibits branching. When the meristem is re moved, the auxin is no longer produced and branching may proceed uninhibited. Plants that are normally very tall and stringy can be kept short and bushy by meristem pruning. Removing meristems also removes the newly formed tissues near the meristem that react to changing environmental stimuli and induce flowering. Pruning during the early part of the growth cycle will have little effect on flowering, but plants that are pruned late in life, supposedly to promote branching and floral growth, will often flower late or fail to flower at all. This happens because the meristemic tissue responsible for sensing change has been removed and the plant does not measure that it is the time of the year to flower. Plants will usually mature fastest if they are allowed to grow and develop without interference from pruning. If late maturation of Cannabis is desired, then extensive pruning may work to delay flowering. This is particularly applicable if a staminate plant from an early maturing strain is needed to pollinate a late-maturing pistil late plant. The staminate plant is kept immature until the pistillate plant is mature and ready to be pollinated. When the pistillate plant is receptive, the staminate plant is allowed to develop flowers and release pollen.

when FIM is done correctly the plant still retains 1 single main cola but the cell deviding from the FIM cut produces 3-8 more branchs on each branch FIM'd. FIM will force the plant to produce more of a yield has been my experince every time i've FIM'd. this includes the sugar shack i'm growing the grape krush i'm growing and the memory loss [urkel x strawberrydeisel}. i'll fim my SFV x White mustang
bubba x white mustang
abusive og x white mustang
cherry ak47 x straw d

when i do this watch what happens :)

1.Auxin produced in the tip meristem travels down the stem and inhibits branching.
In a normal plant the plant produces a hormone which inhibits side branching.....

2.When the meristem is re moved, the auxin is no longer produced and branching may proceed uninhibited.
Pretty self explanatory.....

Pretty simple.....

Each of those side branches has 2 side branches which also grow due to the lack of inhibiting hormone.....

The ideal fim could take about as much plant material as this.....o

just the apical meristem......


t think of the t as the top of the plant.....

if you could remove the very top segment of the t.....

it then leaves 2 side meristems.....

and those have 2 more growing as well....

Done well the top may appear to have as many as 8 tops.....


3 from each arm of the t..... and the node below.......


Thats my perception of what is happening....

sounds like your reading and talking about normal topping...topping and FIM are two different things.

that sure would be nice if FIM increased the yield on every single strain every single time...everyone would do it then. just doesn't happen that way though. anyone ever heard the terms doesn't respond well to topping or FIM?

It doesnt sound that way to me....

Depending how the pruning is done the next axial meristems are either in the same node or the next mode depending on how much marerial is taken from the plant....

If a plant is topped then not only do you take the apical meristem but the 2 axial meristems on that node...

If however you get lucky and remove only the apical meristem and not the axial meristems then you get the fimming effect.....

With indica plants the fim technique is the best way to top and increase the number of flower sites. Works good with some sattys too.

FIM easy peasy bra i take the tip of the growth shoot between thumb and forefinger gently grab it at the base of the shoot slip sissors under thumb and finger slide up a tad and cut leaves, leaving approx 10-15% of the growth shoot. thats FIM if you mess up on FIM no worries ya juts toped the plant


FIM retains a singel cola plant like 1 that wasnt topped it will produce 3-8 new i say again new branchs. which means in the long term your yield is more ya have more tops and more branchs to produce more canibis.

i've FIM;d all the strains i;m currently growing i've even combined FIM with LST and even if the branchs get too tall i'll throw in a suppercroping .

ppl can get as tecky as they wish but FIM and toping a plant are 2 very different methods which produce very different results. FIM dose increase the plants yield the pic i posted before are from a plant i FIM'd all branchs

heres the info on sugar shack

Sugar Shack - Prairie Pride Discounts Apply !

2oz from 1 gal grow bag in fox farm ocean forrest soil and the way i feed them :) give FIM a try vegasguy ya have nothing to loose and everything to gain
 
right on man..thanks maj youve proven to be very helpful since i first started posting on these forums. thanks man. after i get 50m post ill just pm you with all my problems :muahaha: just kidding man.
