need advise on dead plant rockwoll??? :)

hi people i've chopped two males down and im wondering what to do with the rockwoll cube its stuck to the spreader mat?? u can see the cube in one pic and why its stuck in the other pic the root grow though the mat can i cut it out? sounds risky might damage other roots? if im right i've only got one female so i wanna move it to the middle of the table soon plz any advise would be greatly appreciated thank you so much feel free to comment

Never seen a setup like this so not familar with its workings.You can get under the cube and sute the roots from the dead plants right at the bottom of the cube and the cube will come out.The roots will die and may or may not cause issues with rot.Id pull some clones from the known female so your ready for next time and wont have to worry about these males from here on out.Good luck

its a 20ltr tank with a pump at one end and a angled table top i'll try what u said thank u i've seen this stuff that gets rid of old root mass and helps with new rootzym of something like that what do u think? thanks again

You should be ok. It might shock it some. Maybe raise the lights a foot for a day or two.

hey man i kno ur problem it hapend to me once.
k all u have to do is take a sharp razer bade and cut into rows of the rockwell cube towards oneside then cut the other set of rows till u have squares then put them in dirt and lay them outside for 2 days with the complete sunlight then put them bak in ur room and they should be fine ...
