Simple and awesome idea to weight each cup.  I just ordered the same scale you linked in the post. ( I can always use another for my Wine Making) Thanks for the explanation of the whole process and the idea. I keep saying I'm going to take photos and still haven't .. This time I will so it might help another member some day.

@ Rob
I agree with the soil wicking because a few weeks ago I experimented with Foxfarm Ocean Forest soil and small wicking cups I made. All the water stayed at the bottom and it was a mess. I'm just happy I realized it before it was to late. Foxfarm Ocean Forest has zero wick ability.... I actually have to repot one of my small trees because the soil drys out everyday!!. The next soil I'm going to use is on this link AscPete gave me.

The soil I'm going to use for cupping these rooted cuttings will either be the Foxfarm Happy Frog or Pro-Mix BX. I think the soils ability to wick the water is impotant so moisture content is uniform. This with ncyfig's idea I think I'll have success.

For you guys interested in sip watering you may want to check out "wicking pots for african violets" and the "wicking soil mixes" on google.

Here is a video that shows a real good example of wicking african violets on a rather large scale at around 13 min on the video.

I once grew and propagated many african violets using a setup like the one shown in the video.

A couple weeks ago when I removed my rooted fig cuttings from spagum moss and realized how fragile the new roots were, I imediately thought there has to be a better way of doing this.

I have cuttings on the way. I will put some of the cuttings in spagum moss again and some straight into clear plastic cups with a wick and reservoir system. I'll cut the sides off sandwich baggies to use for individual tents for the cutting above the soil line.

My last cuttings went from spagum moss to clear cups with 50/50 perlite/MG potting soil and that worked for me. The clear cups had four 1/4" holes burned in the sides at the bottom for drainage.

I pot my cuttings in plastic solo cups. I buy 11x16" plastic tubs from Wal-Mart and leave the lid ajar. I melt or stab 3 or four 1/4" holes in bottom of cups before adding dirt. I put it over a heat mat with a grow light over them I water by putting water in bottom of tub next to cups.

I tried once in pure perlite. It molded in two weeks. Disaster.

Dan - Sorry this is getting a little off-topic.  I do believe it has some relevance but if you wish it moved to a different thread please say so.  Thanks.  :)

Steve - I also do my rooting outside this time of year but do not keep them in the shade. Too much transitioning to do.  I've been having good luck in this 'cuttings locker' that I built.

  

The hinged lid is attached to an automatic vent opener.  When the temperature rises, the lid opens automatically.  Skinned with reinforced plastic.  Media is 2/1, Pro-Mix/sifted perlite.

Rob - I use to water the same as you and I was still getting poor results.  I'm in the process of teaching myself to 'feel' the weight now.  Look at the 2nd pic above.  They're all rooted cuttings that were potted at different times since 04/09 (Rooting started on 03/30).  I forced myself not to use the scale to water any of them.  The 51 pots on the right are at various stages of living (green buds showing and putting on new growth, leafing out nicely) and the 26 pots on the left (you can't see 2 of them in the pic as they're off more to the left) are at various stages of dying (no activity or budding/leafing activity that has stopped and died).  Just before writing this I went into the locker and sorted all the pots on the left.  Removed and tossed 14 as they were completely dead from overwatering.  The pots were heavy with water and the cuttings were black and rotted.  10 others are still alive and look somewhat viable.  2 (you can't see them in the pic as they're off more to the left) were moved to the right as they had beautiful green leafy growth below the soil.  Late yesterday afternoon, after checking the cuttings that are rooting indoors I added another 5 to the right side.  This is what the locker looks like now:

 

So, since starting all of this, I removed an additional 5 as dead which brings the death toll to 19.  As of today there are 68 in various stages of living which brings my success ratio around 75% or so.  When using the scale I am at 98% or so success.  I've learned a lot about watering with the use of a scale and for me this is a major improvement over killing almost everything 2 years ago.  

Have about 50 more cuttings cooking right now.  Going to start about 50 more over the next few weeks.  Here's to hoping that my ratio goes up.  :)

Have at it, I am fine with this thread going off the rails :)
