Which System?

[CAPnnCRUNCH]

These two seem exactly the same to me (but then again i don't know too much about lighting), which would you go with? had any experience with either company? Any around this price that are better that you would suggest?

I've purchased from HTG before. They are quite reputable.

As far as which lighting system to get, you haven't said what you intend to do with it. If you want to grow one plant, this is overkill. If you want to grow a roomful, then its probably not enough.

You need to think about other things than lights also. For example, a 600 watt HID is going to put off some serious heat. What are you gonna do with it? You have ventilation figured out? MJ wants lots of fresh air.

I could go on but I think you get the idea? I suggest you start here.
