I find that if you keep the rockwool in the black plastic tray they come in then they seem to root faster, it keeps the moisture in, stops mold growing from light hiting the cubes and promotes the roots to pop out as strong light kills them.

As pharma said it's about what works for you, but it looks like your clones are developing fine I wouldn't go about breaking up the cube tho :thumbsup: Goodluck man i'm sure you'll do fine.
KHAN Reviewed by KHAN on . Diary:02/09/07: 8 Pots of Plants Greetings One and All & Thank You For Visiting This Thread 02/09/07 marks the day that I commence yet another Garden Diary. This time I am working in a smaller space approximately 5' x 8' in measure, which is actually a custom partition in a small bedroom. The room has been implemented from scratch. A 4" x 2" timber frame was cut to fit, MDF panels were cut to fit, and a custom sliding door was installed due to space issues. The Garden has 2 x 160mm unfiltered air inlets from outside. Rating: 5
