i lst'd once to a topped plant with 4 colas. looks kinda like a spider. anyways, vegged for 20 12/12 for 10 and in bloom week1. its been 17 days since the last hook was put down. im using coat hanger cut and bent into hooks. my question is...when can i pull these hooks up. it seems that the stems have hardened and are "trained" now. if i pull em will these branches go back up or will they stay the way they are?
