Viewpanel, those lights as Haze put it... are crap, well at least we know 1 is. The bulb that is rated 4200k is definitely crap. For veg phase you want your bulbs rated between 5000k-7000k (this is the blue side of the spectrum which plants need during veg). For flowering you will need to be in the 3500k-2000k range (this is the red side of the spectrum again for flower). So you know the one bulb rated at 4200k is crap, find out what the other one is rated at. As far as the types of bulbs that you are using, you can use T8s for veg and flower.
Now, let me be clear, flowering with T8s is not ideal, but can be done, just don't expect much as far as yeild goes, I did see a thread on here a few weeks ago, this guy was using T8s for flower not impressive but it was working. I use T8s for vegging and they seem to do really well. I keep the bulbs about an 1" away, but not much closer, even though these bulbs aren't hot they can still burn a leaf or 2... Now mind you I'm finishing up my first grow and have started my second grow (1 plant 40 days from seed) and third grows (2 plants 10 days from seed), So I'm not an expert but, with my minimal exerience and all the shit I learned on RIU I think they look good with no stretch. If you'd like I can post a few pics of my girls in veg. For Flowering get some new lighting... if you can afford hps, do it, do it, just do it... i use cfls and t8s so far my first grow is looking ok. any way I hope you found some of this useful. Oh that do it thing... Starskey and Hutch reference... Go Sharks!!!
oh by the way i'm a lil high so if this was confusing i'm sorry
