Lighting source

In previous attempts I had made a LED array. This time around I will be using CFL bulbs. For seed starting a lower power CFL is being used. This bulb was purchased for photo developing circuit boards. It was chosen for the amount of UV rays it produces. In the past I have used it with seed starting with great success.




The hood used to hold the bulb is a clamp on lamp. Have had a pair of these for years and they work great. A 1" x 1" x 4' strip of wood has been screwed to the wall. This will allow the light to be adjusted up and down as needed. For the main grow bulb I have chosen a Ultra Sun 6500K 10W CFL.




This bulb is used in salt water aquariums with small reef tanks for growing coral. It will replicate the sun here in Florida and should be good for plant growth. 6500K lights are also sold for hydroponic use but are much more expensive. This bulb cost under $11 where a similar bulb sold a hydroponics supplier would be $20-80. Time will tell if this is a good choice for hydroponics or not.
