Formulex use on cuttings
I have read conflicting advice with respect to using the product known as Formulex on cuttings.
I'd like to know exactly when to use it - some say it's fine from day one, others not to touch it until the cutting has rooted.
Not sure how to define when it's 'rooted' exactly?
I have one cutting where I can see one little root at the side of the root riot cube, but not sure if that means it has rooted per se?
Any help here would be appreciated as to when I can start using the Formulex.
