there is a tiny fungus growing from the top of my rooted cuttins ( 2 out of 3)
What is the cost of that and do I need to do ?

I air out my plastic container once a day and I keep it in the Sun behind my window, I water them only once when I first planted them.

You may need to leave an air gap in the container at all times.  Sounds like too much moisture/humidity.  With the sun shining on it, the moisture builds up quickly and those fluctuations can inhibit mold.

I can only relate my own experience. When my cuttings grew a fine gray fuzz on them I asked a local expert what to do. He said to use the least harsh method first. He told me to mix a teaspoon of bicarbonate of soda in a quart of water and spray the fuzz with that. It did the trick. Fuzz is gone and has not repeated.

Wet a piece of cloth with diluted bleach and wipe off what you can then spray that same solution on the cutting and then air it out until it drys. Just don't let it out of the humidity bin too long, just long enough to dry it a bit.

will baking soda work?

I had some cuttings that molded. I put them in a bleach bath and rinsed the container with the same solution and cooked the medium and it recurred. I did this twice and then gave up.

I had a cutting with a terminal bud molding. I put it in a cup and left the humidity dome off. Mold dried and bud underneath is green and about to leaf.

Curiously, I have seen blue mod and orange-red mold in the medium and on fallen leaves  that seems not to affect the cuttings.

Not sure if it will kill the fungus but it shouldn't hurt the cuttings. You can put baking soda in water to keep cut flowers longer and mix it into the soil to sweeten it for tomato plants. At least that is what I've been told.

I have decided to contribute although as I get older, I realize I am almost never right about anything.

Bicarbonate of Soda and Baking Soda are different names for the same thing. They have a PH level of "ABOUT" 9. I have not tried this on figs, but the reason they should work is by changing the PH level of the mold growing on the cuttings. I have noticed that mold ("powdery mildew") on roses, can be pretty much eliminated by spraying with a mixture of Baking Soda and water (raising the PH), or by spraying with a mixture of Vinegar and water (lowering the PH). Either one seems to work.

I believe that Frank is also correct as fresh air circulation seems to prevent molds.

I am afraid of bleach as I once killed a number of Iris rhizomes by soaking them for too long in a bleach solution. Entirely my fault, but I still refuse to take the blame. Done correctly, it should work (I think).

As with anything I say, verify this for yourself. I hate to think about all the plants I've killed, thinking I knew what I was doing.

Thank you all

Well, even in fresh air, I've gotten mushrooms growing in containers.  Of course, they only help the cutting when you plow them under, but they scare me silly!  Now, I get the mushroom thing, and been here so long, understand the mold thing.

Still working on the gopher thing..........

I brushed it off with a soft toothbrush , I used baking soda and water, I also drilled a pin hole at the top of the container .
let's see how it will work,hopefully everything goes fine.

thank you all

Hi F4L
i would isolate the ones with the fungus and put them in another bin.

if it had better roots i would risk it and put it indoors without any lid.

later.....

The fungus came back on one of them , I repeated the process with the baking soda and lets see what happens.
Is that contagious? Will it affect the ones next to it?
I also made the hole a little bigger.
is this happens again , i'm going to use bleach

you will learn to use almost no water when you have a close container. the moist moves around, but does not escape, you may need to take it out, and air it completely to dry some, maybe even dump some of the soil and replace with no moisture soil.

the spores are in the air..and will grow again and again...

Drip some candle wax on the tops.  

Spray the inside of your gallon "greenhouse" with a peroxide/water mixture.  I spray my cuttings as well.  I use 2 parts water to 1 part peroxide.  USE AT YOUR OWN RISK!!!  This works for me but I have to say the other.

When using bleach water, the best way to completely neutralize the bleach after dipping your cutting in it,
is to then dip the cutting in vinegar to completely neutralize the bleach before rinsing it off under water.
They chemically cancel out each other's PH. It works!

You'll get many different answers on his one just like which is the best potting soil, fertilizer, way to start cuttings.  I have tried bleach and antibacterial wipes with little success.  Hydrogen peroxide (3%) undiluted applied with a Q-tip has worked the best for me.  The photos you provided really don't show that bad of a mold/fungus issue in my opinion.

Another great idea that I have started using is to clean the cuttings before starting.  Use an old toothbrush and lightly brush the cutting with antibacterial soap and water.  Let the cutting sit at least 1 minute before rinsing with water then dry.

My first batch of cuttings were started without the antibacterial soap cleaning and I had some mold issues.  The second batch of cuttings I cleaned with antibacterial soap and didn't have any mold issues.  I was also a little smarter the second time and more watchful for humidity issues so maybe this was also part of the reason I had less mold issues the second time.

PH can be a significant barrier to mold. They need a certain level of PH.  Just like spraying a solution of milk inhibits powdery mildew.  I think maybe experiment with what end of the ph spectrum it doesn't like.  A couple of drops of a vinegar solution, maybe lemon juice or baking soda solution.  Some air circulation is beneficial also.
