Ok, so I am new to this whole growing thing and I have been doing extensive research to educate myself on the proper way to have a successful grow. However I am a bit stumped on the lighting situation. I plan on using CFL bulbs as my sun replica but I cannot decide which is the right amount of bulbs needed to maintain above average to optimal growth. My small grow will consist of 4 plants and will be grown inside a 3x2x6 foot area. From what I saw while researching is that a good rule of thumb to follow is to have 7k-10k lumens per ft^2. However I have learned that lumens in CFL bulbs are not additive, meaning that if i have 68w bulb producing 3.4k lumens and I put another 68w bulb producing the same amount of lumens, that those two lumens will not yield 6.8k lumens and instead is just 3.4k per bulb.
My initial plan was to use a 68w bulb to shine down on the plants and to have two 27w bulbs on the sides. The 27w bulbs produce 1.85k lumens.
I guess what my question is is if the above light setup is enough to sustain and produce a succesful and somewhat fast grow.
If i was unclear on anything or if you need more information to help answer this question please let me know and I will provide.
