Merry and I were traveling our local hardware store when we happened upon a 65 watt CFL Work Light in the 6500k spectrum. We decided this would be a great upgrade from the 23 watt cfls in the 5000-5500k. After destroying the assembly we removed the power supply and installed the new bulb into the box. Since the ballast was remote we installed it on top of the box. Now we have 1 65watt bulb in the 6500k spectrum with our same ventilation setup. All and all, we feel it was a great upgrade. It provided us with a little bit of extra space, even if it was only an inch, more wattage, and though we don't know the full specs of the bulb yet, we assume more lumens. Which leads into my second part of this post...
I have heard that watts are the most important factor to your plants growth. I have also heard that lumens are the most important. My belief is that lumens are the most important part of the grow, but im curious as to if there are better "quality" lumens than others. I understand that the spectrum of light affects how the plant grows, but does 1 65 watt bulb put out "better lumens" then another?
