I agree with CanGroIt on the 400. Stick with that. You can still use it for veg then for flower. Mh is more preferred for veg but hps will do the job.:thumbsup: As for the price on a cfl setup for seedlings.... 2 bulbs for 7 bucks, clamplight around 7 bucks, Y for both bulbs 2.50. Less than 20 bucks for the setup and you can use that in a little box or something and place anywhere in your place. Or you can just put them over the seedlings and run the lights 24 (that way any other light wont interrupt their dark time) til they get big enough for that 400. Thats just what i have done in the past. You can triple that it id be around the same price as a replacement bulb for that 400. Just something to think about. Hope that helps.
