Rafed,
I usually start my fig cuttings in baggies. There are many good reasons for starting them out that way. My personal preference is to move my cuttings from barely moist paper towels that are within baggies whenever I see a small root emerge on the cutting and/or one of the leaf buds or terminal bud begins to open. There are reasons for doing that too. FYI, use Kleenex VIVA brand paper towels because they are MUCH BETTER for use in the baggie method.....and there are reasons for that too.
Yes, there are three holes only in the bottom of those 16 ounce plastic cups. Those are recycled cups from a couple of years ago. When I root fig cuttings in just the plastic cup without a peat pot inside .....three holes in the bottom and two on the side work fine for me. However, when using 24 ounce plastic cups it is important to put more holes in the sides of those bigger/taller cups. If you don't, it can take much longer for roots to form and once they do form.......they can easily get damaged from inadequate venting of the carbon dioxide gas that forms during the rooting process and within the rooting mix.
However, when working with 3 inch peat pots inside of 16 ounce plastic cups there is enough venting going on between the walls of the peat pot and the walls of the plastic cup.......where only the three holes on the bottom are needed. Just be sure to put your cups on a WIRE RACK. Those holes are not just for drainage....they are needed for getting "air to" the roots and getting "carbon dioxide" out of the rooting mixture. Bad things can happen to your cuttings if your rooting zone does not "breathe" air in and exhale CO2 gas out.
The better ventilation that you can get to the "root-zone" area of your cutting...... THE FASTER ROOTS WILL GROW AND DEVELOP and the less likely they will get damaged from CONDENSATE (not talking about perched water here) and damaged from acidic carbon dioxide.
Bottom line.........three holes in the bottom of a 16 ounce cups using a 3 inch peat pot.......works just fine, if you put them on a wire rack. Give it a try and see for yourself. Bet you will like this method!!

Alan, Dennis, Rufus, Dominick, Ken, Chuck......thank you all for the feedback!! It is people like you that encourage others to share some of their work.
So here's another rooting tip that I will share with just you guys (don't tell the other silent lurkers!!)
Whenever you see one of your cuttings that is in a rooting cup going limp on you......put a kitchen match just barely inside of the drainage/vent holes and move it around a bit to make sure that the hole is still open for air flow. GENTLY till the top crust (surface) too with the match stick. Sometimes that is all it takes to revive a wilting cutting. It often is just a carbon dioxide venting thing........

Tomorrow I will take some "summer" cuttings from another heirloom fig tree that I have found. I'll be rooting those cuttings by another almost foolproof method. Will be taking pictures to document the procedure. Stay tuned.......
