Oh, a few more things...
1) I think I've found a relatively cheap pH controller which can trigger a small pump to offset rising pH. Would this help my cause or could it just make things worse?

2) I've read about a thousand different (and often conflicting) opinions with regards to HPS vs. CFLs. I am planning a small/medium sized stealth grow cab where heat is likely to be something I will be fighting with. Can someone tell me if a 150watt HPS will be harder to deal with than a comparable (150-200 watts) amount of CFLs?

3) I fully expected a bit of a flaming by asking my question. Asking the easiest way to do something on ANY forum is kind of a nice way of shitting on those people's hobbies/professions. I should have given more of an explaination and phrased my question differently.
