Patience is a virtue mon ami same time you dont need a softball sized root ball to put it in dirt

I would just up the temp a bit, rooting compound and clonex should do the rest, also, keep them under minimal light, otherwise theyll focus on attempting photosynthesis, rather than throwing roots down. I usually get roots in a 10 days +/- 2 days

chnage rez more often, if dirty? this is probably environmental... additives don't do much for overall speed.. if you do the rh right and other things right it might shave a little time off. i'd compare labels of the products you want to use... if it contains the same stuff, there's no reason to double-dose it... the plant only needs a tiny bit of building blocks in this time.. it's not growing much. read up on vpd for clonse.. dont give too much too soon (light/fert) and they tend to root faster. Can be genetics too... some you can just pop into a glass of water and they show initial signs of roots within 24-36 hours. There's no miracle product out there.. if having good results it's 90% environment.
