My mix from the start has been a variation of what I use for my Grow bag garden mix.
The grow bag garden mix is setup for wicking and is as follows:
2 five gallon buckets full peat moss
1 five gallon bucket well rotted horse manure or compost or worm castings
1 and 1/2 cup garden lime
1 large coffee can full of perlite
1 handful of epsom salts
However I have upped the perlite to about 50% of the mixture, lowered the composted horse manure to 1 gallon and have dropped the garden lime since I was unsure what PH figs liked. All of my cuttings seem to be doing well in this mixture right now. I had read the other day that equal parts peat, sand, perlite, was where I wanted to be so I bought sand to try it and obviously that didnt go well.
I appreciate the explanation on the antimicrobial and warding off pests, that was something I hadnt known.
Im still relying on their will to live, to outweigh my mistakes :) As for the video, the ones I just had in the sand mix and removed from the sand mix were straight out of a vertical rooting container. One had maybe 12 1.5" roots and the other had about 20 2" roots. Definitely not a rooting system yet. I successfully took them out and moved them into a different mix, losing only 5-10% of the roots on each. I think I got lucky.
