Why not plant cuttings right into soil?

I have minimal experience, bout 30 clones.. First time was 10 and 8 made it second time was 20 and all made it.. Cloning solution then straight into solo cups with soil put under a single cfl and watered with a spray bottle.. No dome no heat mats just kept it simple.. Worked for me and I'll keep doing it that way till it don't work anymore..lol.. My .02..

heres how I do it and I grow from clones I have cloned of clones from the same 3 plants for 5 years, ive also got a clone only that takes 3 weeks to root so am experienced at feeding clones which is generally discouraged but necessary if you got a high sativa dominant strain, I use jiffy pellets
glass of pH adjusted dechloinated water, take cuts of whole lower nodes and put in water continue til u have desired amount lol, then take each cut underwater then dip in clonex then put in pre-soaked ph adjusted jiffy pellet in a dome with a high roof which has been sprayed wet with the water, within 5 to 14 days u will get a shit ton of roots, the mainpoint is to avoid air embolism ingression so cut under water for win imo peace
