Chromo, do not remove the plastic from around the rockwool cubes! It helps with the capillary action, keeps the cube intact, & once the roots start growing, it keeps them from being exposed. Your buds are awesome! Anticipation is a killer! Makes it oh so tempting to harvest a tad too young, but DONT DO IT! Just follow the trichromes guys, no matter what the leaves, hairs or anything else is doing.... follow the trichromes.....
-- So Chromo, if these clones take off for you, do you think you'll be making a large part of your grow from them? (BTW, when you take cuttings from budding plants, or even veg plants, you can keep them under 12/12 & they will still do their thing, maybe even better. No stress from going from flower to veg & back again). Have you read up on re-vegging? GREAT thing to do. Gives you many, many branches to clone from, or a REALLY heavy producer the second time around. If you flower it out again, you will have to thin the hell out of it though, still almost forcing you to clone it. But you may want to give it a try with your favorite girl. She's worth it.

-remove the plastic only when you plant it into soil.
