The seedlings are starting to work on their second pair of leaves, now. Everything is going great so far!

2. Leave the wrap around the rockwool. Next time I would suggest using grow plugs, they wont get over saturated like the rockwool cubes can.
I'm using a 18/6 light cycle, right now. I heard that a 16/8 light cycle would produce more females, and a couple of other factors.

And, purchase a pH/EC/TDS tester if you do not already have one. Very impotent fer hydro grows. Can get a Milwaukee SM 802 combo pH/EC/TDS tester off that e place auction site for 135 bucks (good deal). Deff need a way to test once you put in ya 'dro setup and start feedin sum nutes. Best of luck wit ya grow:rasta:
I already have a pH tester, and I went and bought some CFLs. I am also about to get a fan blowin' on those babies as soon as I can. Thanks for the help.

Pete. rockwool only has problem if you leave it sitting in water...It wasn't designed for that. It was meant for drip or ebb and flow...where water is cutoff for extended periods of time.
Thanks for the help!

[align=center]QUESTIONS[/align]
1. Is it too late to change to a 16/8, and would it be wise to do so?

2. Am I allowed to place the seedlings in the system whenever they show growth outside of the rockwool cubes?

3. bongerstonerd00d said that people use a few 40-42 CFLs, and I was wondering if I'm able to use the 4 60 watt CFLs that I bought today. Is it going to be too powerful for the seedlings, or do I need to get something stronger in the CFL class??

1. Starting to show the second set of leaves.
2. The CFLs that I bought today. Are these good enough?
3. The pH tester that I had bought earlier last month.
4. The duel-air pump that I will be using for the air-stones.
5. The airstones and hose that I will be using.
