It's not as important in veg to keep the cfls as close as possible, when compared to flower. The main thing you want to avoid is stretching and heat issues with cfls in veg. As long as your not stretching and raising the temps. too high, you want them as close as you can get but honestly, I kept mine probably 5 inches or so away and I had no stretch or heat issues. 10 cfls, 26watters.

Until you get your setup and grow style dialed in, go by the general rules, the more light the better. IR, won't steer you wrong. He's right that OF is hot but as long as you don't fert too early, it's satisfactory for seedlings. Don't be surprised to see a little deformity in the early leaves/first round leaves. I use OF from start to finish. Always water from the top. Always.

As far as drainage holes are concerned, I like mine as big as possible. I make my own pots, and use a 1/4 inch drill bit for the drainage holes. The bigger the holes the less likely water will get trapped on the bottom and it also allows more oxygen to get to the roots. You will be thankful you added perlite. IMO, always add perlite.

I've used both 18/6 and 24/0 and saw no difference. The only reason, I don't know if its true or not, I used 24/0 last grow was I thought the plants would show sex earlier after the light change. My human thinking, thought that since they had never been exposed to dark that the first exposure would 'kick' them into flower faster. Took the ladies 3 days, which was quick IMO but I have no evidence to support either way.

Also make sure you don't water normally too soon. I had an experience once when I watered normally too soon and the seedling hadn't rooted down far enough and the entire thing, root and all floated to the top of the soil lol. I was pissed, but stuck the girl back down in the soil, and she grew fine. She was stunted, as you can imagine, by the experience but it worked out fine, she was only maybe 7 days behind the rest. I use a spray bottle until I think the ladies have rooted down far enough to handle a full on watering.
