Vermiculite is jailbait, lol....i heard someone went down big for having a bag of that.
Is buying bags of soil in mid winter not a bit jailbait as well? Swings and roundabouts I guess.
Pompey, not really hard work. A bucket or bin in your back garden and throw some enzyms in and it breaks down all that root matter for further grows (you can get a box of organic composter for probably a 5er at your garden centre). You don't have to tlc it everyday. You could even chuck some of your kitchen and other garden waste in there...soon you'll be growing organic
In fact, to save time emptying the pots, just rip a bit of the rootball out and then stick your clone in there and no need to amend.
Do you find any difference in the second run Wisdom?
