Yes, I wouldn't consider anything less than 400 for indoor if I was doing it that way, but I wound up getting a 125w+reflector/socket for 80. Hopefully this will work good enough in a traditional 5 plant square space to bring them 6-8'' within 2 weeks or so...i agree with superman. 1 big one and some smaller ones. im using a 43w and 4 26w and they are doin fine. And ya im doin cfl all the way but when i get a bigger place and some more money ill be getting a 400w hps (about 200 $) for flowering. But just for veging cfl's are all you need.
OK, I just cancelled the order for the 125w cfl package. I'll shop around for a cheap 150-175 mh ballast kit. This will take my worries away for sure. I appreciate you saving me some headaches manIt won't work for them up to that size, you will need some more. I have 2 105's and they were not enough once the plants get a bit bigger.
