oooo, see the only concern with the rockwool cube i had was that this will be my first grow..and i thought i would have to transplant them into the perlite without the cube...i was scared and i didnt want to damage the root system...im a beginner. But if you can just bury the cube in the perlite then PERFECT! ill go pick up some cubes today and some Vermiculite! thanx a lot man...ill be posting a grow journal shortly...would love ur feedback
