i said all this stuff earlier lol
5 days is my fastest to have actual roots
Not nubs but roots
To throw a wrench in there
I have clones that are doing well
That were literally plucked from the plant and stuck into the same rockwool cube as i topped it from.
Then fed the same ppm of the large plant about 650 to 900 ppm ...... do you think they grew or died? ..... they grew just took about 3 weeks for roots to pop. But they did not droop or get too pissed off about it
Just my 2
