Hi AFN, I'm upgrading and my question is should I get a 250 or a 400 hps? I want my buds a lil more dense than the 150 sun system I have. While it does do a good job, the hood is too small in my opinion. My space is 2 by 3 and 5 foot tall. Any opinions are greatly appreciated. I've grown outdoors for 15 years but only about 1 year indoors thanks!
