Rooting fig cuttings

I've been trying to root fig cuttings with limited success (two out of perhaps forty) but at last seem to be getting somewhere.

The first "method" was pretty arbitrary - stick some cuttings into a black plastic bag of compost placed where they get occasionally misted. The cuttings stayed alive for a very long time but did nothing. They eventually rotted due to drowning. The compost had compacted and wasn't draining.

The second method was putting some cuttings into an aluminium tray in mixed vermiculite and sand in a Ziploc bag and leaving it outside for a few months without additional water. When opened up, about 50% of the short two node cuttings had rooted and got a few leaves. These were transplanted into a small plastic pot of compost, and one cutting of each variety seems to have taken.

The third method was to use transparent plastic cups filled with vermiculite, coarse sand and bark mulch. Most cuttings were about three nodes. These were left outside under occasional misting, and a few - to my surprise - rooted. Siimilarly transplanted to small pots of compost, where a few have taken.

The fourth method is the so-called "fig-pop" where a 10cm x 50cm plastic bag has about 20cm of mixed vermiculite, sand and compressed/reconstituted coir and the cutting placed in it. The base is pricked with a tooth pick for drainage, and the top folded over and stapled after drenching with water.
Over time, the mix has varied, the best results favouring 50/50 vermiculite/coir and leaving out the sand.

Initially they were left inside in a darkened room, but developed mold after a few days, Taking them outside into the light and leaving them there seemed to sort that out.

I've had mixed success with this... initially nothing much happened and a fair number died because of lack of moisture, After topping them up with water and ignoring them for a few months, quite a few have developed roots and grown leaves, but the roots are not yet that extensive.

The fifth, and so far "best" method, is the third method with the addition of putting the plastic cups into large transparent plastic storage boxes - a mini greenhouse sort of arrangement - and leaving them outside to control mold.

The issue now is how moist to keep the cups and whether to leave the boxes in the sun - it's starting to warm up. The developing roots clearly don't like the sun, so I've started putting the cups with developed roots into darker cups.

In a week or so, the next step will be to "up-pot" the established cuttings. It's still a bit cold for that, though.

Then the decision as to what to actually do with perhaps several hundred small fig trees. My problem is that every pruned branch from my collection of trees gets converted into several three or four node cuttings.
