We needed some chard for the soup pot, so the harvest concludes this experiment.

Plants are very healthy. The MM has stayed at a good moisture content from top to bottom.  The roots did eventually work themselves down into the gravel.  I couldn't get a picture that showed it, but the gravel took on a green tint as the water level dropped.




Water Usage Chart:


The MM is nicely damp throughout, and the surface of the MM is staying damp too.

Conclusion: Using wicks worked great.  My 3 wicks were strips of an old cotton terrycloth hand towel.  I don't know how the wick material or number of wicks influenced the results.






I'm trying one more variable.  From what I've read, a lot of folks used pea gravel in the tub, so I'm going to try that. (no wicks)  I had used crushed rock for my first attempt.




Three chard plants that I had harvested from before transplanting.

Thoughts ....
The crushed rock was impervious ie. it won't or don't soak up water . Certain pea gravels won't be so clever either. Granite or basalt  rock are common impervious rocks .
 
Now if it were first fired broken clay pots you'd have an ideal wick , crushed & broken fired clay house bricks might be ok as well so long at it is not the impervious very dense engineering brick , crushed concrete pavements or pavers blocks may be ok so long as they are not water resistant .

I suppose you could use any gravel around a nylon sock filled with pure vermiculite & take the sock from the bottom of the container up into the top two inches of MM etc. that would make a fantastic wick ..
Wash the socks first and rinse them several times in warm clean water to remove all traces of detergent /bio action cleaners .

No use dragging this out.  The MM is nearly dry, and the plants are starting to look stressed.

Conclusion:  The pea gravel didn't work either.  Don't make a wicking box without a wick!   Razz

i did a few, on one i used a sock to about 8 inches up.  on the other i used a 4 inch pot in the bottom to reach down into the wáter below, but i added a rope to extend the extra inch to reach the bottom and absorb the wáter some more. i did it with a few goji berries. at the time they are dormant, but i would get pics one i get some fruit.
