Fimming With My Blaze: A Complete How to FIM Guide

A few questions:
-Could you combine this with LST or UB's 4 cola method?
Its better to do either one or the other (Top or FIM) so id suggest you choose one or try both on 2 different plants to find which you prefer. FIMming and LST go hand in hand and will help to create a perfect canopy.

-Can you Fim multiple times? If so, can someone run through this procedure?
You can if you want and you just do the same thing with whichever branch you want to FIM.

-How much does your dry harvest weigh per plant raised with his method?
Nobody can tell you how much you will yield per plant because there is too many things to consider and every strain, every setup, every feeding schedule and environment is all different from grower to grower.

Would this work well with hydro? (specifically stinkbud's aeroponic).. Or would you need bigger net pots and more spacing?

Hey Blaze... what's the exact composition of your medium?

Coco...(brand?)... what else?


btw has anyone ever LST'd first and then FIMmed the lower growth?

I have to downsize for my 3rd grow from a 400w MH/HPS to a 150w HPS in a a 2'x2'x4' tent. My plan is to have my plants finish at 2 feet or less since the 150w can't penetrate much more than 1.5 feet or less. I'll fim at 3-4 nodes from seed and then flower once the new shoots are established. I'll be using 1.6 gallon square pots (6"x6"x9") and will try to squeeze 3 plants in the tent. I plan on tying down the bud sites to give them a lower profile so the light can penetrate efficiently. Kind of like low stress training, but not 100% Does this sound like a good idea or a bad idea?

I fimmed mine but the top keeps trying to grow out new leaves... is this normal..? I think I'm gonna end up with 8 main stems because of this.

edit:

wow.. I think I missed the FIM, lol
Is the main stem/shoot supposed to continue growing even though you snip off 80% of it?
Cus mine did, so I was like wtf and snipped it again...

Now I have 4 nodes spaced within less than 2 inches of length... so that means 8 stems?
Also, my FIM cut produces symmetrical growth each time, = 2 new shoots out of the side + the new growth continues to grow with the snipped off leaves. It's kind of like topping.. except the top grows back.. wtf?

but since my plant is growing slow as fuck I won't know until weeks later if this will produce strong stems.

I guess fimming is a way to reduce internode space.. haha imagine if you FIM the plant from the first set of true leaves until it has 20-30 nodes in less than a foot of stalk. It would have no fan leaves on the main stalk though, except for the ones coming from the new growth. lol

Well here's a picture... read my previous post then comment. Am I making the cut in the wrong spot? The top growth continues to grow new shoots after the FIM, except the fan leaves have already been cut off before they grow out.

keep in mind that I did cut all the way through the stem, just like I've shown in the picture where the 3rd FIM cut will be.

Yes it works the same with hydro but the idea is to create a wider canopy so you just need to grow within your space limits and not let it get bigger than your space allows.

100% coco with nothing added to it.

Tying down is a great way to maximize the benefits of FIMing.

I think you are cutting wrong. Forget the cutting and forget the scissors. All you need to do is rip off most of the new growth tip with your fingers. Its hard to do it wrong.

Mr.Blaze,+++rep+++
I just tried this on 4 of my girls and am hopeing for the best. Those pics are nice as hell to print out and have there w/you when you do it to. I do have a question though, On my girls none of the new growth (before you cut) are as symetrical as the new growth in your pics. Does that matter?, or is it just plant genetics, differnt strains or something along those lines?
Also, do you use coco as soil or hydro?
Thanks,love this post+++rep+++

Im not sure exactly what you mean but growth will vary between different strains. Non symmetrical branching or uneven canopies can be fixed with a bit of tying/training.

Coco is closer to hydro than soil. Coco specific A+B nutes work best.

Can you take a picture and point to where the 3rd shoot is suppose to grow from? I get that 2 new shoots are suppose to grow from where the leaf stem connects to the main stem... but where exactly does the 3rd one grow from?

hmm... I see no other way in cutting it... maybe my plant just grows differently when fimmed?

could you possibly show me the cut location using my own picture? your plants look way diff than mine...
I prefer to use scissors, just looks cleaner..

When you cut off the new growth, do you also cut off the new fan leaves that haven't grown to full size?
In your picture you say to fold them down, but in the next picture I think they're missing as if you've them away.
I've tried that on one of my other plants but then that just results in topping...

i've "fimmed" it 2 more times since that pic.. lol.. it's got like 10 growth shoots coming out near the top 4" of the plant

I've done topping, fimming and noticed the plant slow down. I supercrop and it works better, i get multiple tops without much slowing down. nowadays I don't do anything and still get tons of tops and bushy plants. :)

so can sum1 give me a brief run thru on how to get a bush plant???? i fim ? and then from other shoots that come out of the sides...fim as well????
 
fuck i missed haha best technique for mature plants use uncle bens tech for seeds or small clones if u can. great info on this thread and great pics. happy growing and always top your plants

Damn Blaze, I just read throught this entire thread and I have been uing the FIM technique for a while. This thread is right on the money and completley explains the process. Thanks brotha for simplifying it for everyone. I have found that when used in conjunction with lsting or superropping, it is the best way to turn one plant into 4. Blaze, you definatly got this shit mastered.
Hey, by the way, how did that monstor that you started flowering in May turn out?

This was super helpful! Applied the fim tactic 2 days ago, and I'm seeing the new growth sites very clearly already. Sweet! Thanks MBlaze, you are the shiznit. +rep
