I change Medium next grow,
From hydro corn to rockwool cubes (4×4×3)

I have some pre veg clones 8 amnesia , they allready 2 weeks in the rockwool cubes
And yesterday 8 others (mac1,zkittles,chemdog91)

The plants that 2 weeks into rockwool(4×4×3) habe grown some long roots out the blocks ,
Not sure what to do;
1 .leave it alone?
2 .put the 2 weeks into roockwool cube on another cube (4×4×3)
3. Trimm the long outgrown roots?

Everything is in veg min 19 hours light
