hi there guys ive been given cuttings in earth. its my first time trying hydroponics. I'm thinking of cutting the rockwool cube open in order to fit the cutting in the cube. they only in two inch pots but they root bound what you guys recon. tuck all the roots inside a 4 inch cube. or if they long enough leave a little bit hang out the bottom of the cube what you recon guys. any advice would be great. terrier
