Choice is between 4 cobs, can't tell them apart. Help?

Only you can determine what qualifies as tried and proven methods.

You can look at youtube videos and grow journals. But those can be, and often are, faked. There are a quite a few unscrupulous vendors out there posting their so called results without any verification.

You can use google and do some searching. There is some good research out there that can help you decide.

But ultimately, you have to decide what is best for you. It is your environment. Plus you may not have any skill or luck with plants. In that case it doesn't matter if you are running 1000w HPS or a 8w A19 bulb.

The science points to white light weight towards more red as being more beneficial for flowering and fruiting plants. For vegetative plants, more blue works better.

As was mentioned before, you can't go wrong with either so you are fairly safe. You could probably mix them up as well, spread them out between 2700k, 3000k, 3500k, 4000k as you don't have to stick with just one spectrum. The opinions you get will vary wildly based on people's different experience.

Thanks man. Since I'm only using 4 or maybe 5 cobs It's a bit hard getting all those different cobs in the setup. If I want the same coverage everywhere. I was considering this: (Sorry I know it looks confusing, but it was the quickest way to do it)

So one side has a blue and red, the other side had red and blue, and the middle (Green dot) could be a 3500k. But let's forget about the green one for now. If I only did those 4, wouldn't I be better off with 4 3500ks? instead of 2 2700ks and 2 4000ks for instance?
