8, 45watt CFL's thats a ton of light, prob 2600-3000k lumen each. so thats like around 20k lumen much similar to an HPS output. I'm running around 25,000 lumen (light output) with 14/ 26w bulbs
the 4 pod cluster that you have them in, I would'nt put them any closer than 24-35 inches.
If you want them closer you should spread them out more rather than a 4 bulb cluster, you can get a Y connecter for $1.25 at ur hardware store to extend the bulbs away from each other. Also CFL's emit more light from the sides, rather than the bottoms, so you should goto your local food store and hop down the baking isle and grab a couple alluminium cake sheet pans to use as reflectors,
the connector will also tilt them a little more and emit more light especially with a reflector.


or.. use lower wattage bulbs if you want them closer.
also a suggestion, is. your pots are too big at the stage they are in. your little square pot "Guy" he is rocking out. use that as an example. he is also the furthest away from the lights & in the smallest pot.
growdemon Reviewed by growdemon on . CFL's I am new to growing. Do you think that 8 45watt CFL's would be adequate at such a distance in this room? They are prolly 3 1/2 or 4ft from the plants. the box is 4ft x 4ft and it is 8ft tall, the top 2ft having no reflective lining. The back plant wilted on me today, after accidentally snapping the branch. The 4 to the left were started from seedlings. The middle one's sat outside for about 2 weeks collecting rainwater.That's why they are so much bigger than the one's to the left. I tried to Rating: 5
