Bubbler Cloner on Smaller Container

I've decided to try some drastic changes on my bubbler cloner. First mod - smaller container. My original container was a 12L plastic box. This one holds only about 3 liters of water and is roughly only 10 cm deep. Second mod - new air pump. I'm also trying a more silent air pump (though it seems to have much less volume output than the original pump I used). Third mod/change - more than one cutting per site. Here it is populated on all 6 sites with 3 fresh cuttings of Thai Basil each site. I did put plastic cups on each site as humidity domes - the cuttings seemed to be wilting quite quickly.

I also need more clones of Mint and Genovese Basil. There was another tiny plastic box lying around that I use to bottom water some small pots. I decided, I'll give it a try despite it holding only a little under 2 liters of water. So I did three sites with Mint and the other 3 sites with Genovese Basil. The mint cuttings had super tiny leaves so I decided to overpopulate each site with 7 cuttings each but did still just 3 cuttings on the basil. I only placed humidity domes on the mint since the basil seemed to be holding up quite well.
