Some help with cloning

So i accidentally broke the main stem of my plant about 8 nodes up. I put some soil in a solo (party cup) cup about half way and put my stem that i broke off in there. its been in for 48 hours now and it still looks really healthy, nothings drooping, no yellowing etc.. i cut the tips off all the leaves because i noticed thats what other people were doing and that i should probably do it too..

what i really want to know is how long does it take for a cutting to root in soil? ive not used any rooting hormones or anything like that.. i just the stem diagonally and then split it about half an inch to expose the insides. i have the solo cup with the cutting inside a ziplock bag and i foliar feed with dechlorinated water.

i've cloned in dirt, no hormones, just patience
2 weeks minimum, that should begin rooting, keep the light low and the soil moist
