Hells bells, I was right! Nice setup Jam! :thumbsup: Pardon my drool... What are you using for reflective lining? That looks almost to be too shiny for Mylar, but maybe it's just really good quality?

Using this screen method, how long should seedlings stay at 24hr light? Is a period of 20/4 light advisable before putting them into 12/12 flower mode?

And thank you Brooke, I was indeed thinking about replacing my current tubes as they only crank out a paltry 1900 lumens I believe. I'm sure they're cheaper than the Agrosun variety and nearly as bright. Good enough for me, trying not to go over-budget here.
