Each T5 fluorescent light is 54Watts and they run for like $35 for a 4' fixture. 2 for a 2'x4' area is the absolute minimum (thats what i have) Id like to bump it up to 3 or 4 per 2'x4' area.
What's the price range for that many lights? Also, how much wattage use is each strip? This kind of rack looks like it works great. I was tying different good seed starting methods. This looks like it. I have also seen people use this style outside with a hummidity cover and no lights.
