Ok so I'm gonna repot my plants, and I have some gravel, I was thinking of putting it in the bottom of the jugs to help with drainage. I was hoping this way I wouldn't have to cut holes in the bottoms as I don't want to deal with the mess. what do you guys think?

I went and got 2 more cfls, so now i have 4 26w and a 50w hps. The plants are turning a bit yellow, I gotta check on the ph, but i still haven't gotten any strips yet.
