The ballast is great, same one I use never had a problem with it (only had it for a year so not very long). One thing I did have a problem with is my timer, apparently digital ballasts have a really heavy start up load and I blew my timer last week. So watch for that.
I would personally go with an aircooled hood. I got a cheap wing one to start and used it for about 2 weeks before I realized how much better a proper hood is. They are way more expensive but work a lot better. That way if you have heat issues you can easily hook up some ducting and it's solved.
The babies look great. I'm subbed. I got two white widows going right now. One from Vision and one from Dinafem both feminized, both just cracked dirt. Be nice to see how yours turn out.
Good luck and have fun
