So, I made a setup similar to
this, that will grow about six plants. I plan on getting a 600 watt HPS for when I flower, but I'm going to veg with CFL in the mean time. I plan on getting
these bulbs; they're 105 watts (500 watt incandescent equivalent). Would it be smart to have one bulb for each plant, or could I get away with three down the middle? If I get six bulbs, that comes to $137 not including shipping. I might as well be getting a 600 watt HPS already for that much!
EDIT: I just realized they're over 11 inches long! I intended to have them hanging vertically, but now maybe I'll have to make a hood and hang them horizontally...
