I read for about 3 hours last night and most people say don't do it. But some people say you'll get good results with both. One guy said that 6500k is full spectrum so it has red in it to cover flowering.
If anyone has actually grown all the way through with 6500k can I see what they came out looking like? Or at least describe if they came out better or worse than if I change the bulbs.
I'm growing under 12 t5s, so to get the bulbs I want would be like $70... so if the 6500k will be good, then why spend the money.

Here's the easiest way i can explain this.............the sun has a spectrum that plants in nature seem to enjoy........if you can find indoor lighting bulbs that can mimic the suns spectrum your doing yourself a favor following mother natures lead, so imho a combination of both 5500k and a far red are PERFECT for flowering....just my opinion.

So maybe I can get away with say... changing half of them out? Save a little cash that way at least. I was looking at spectrum charts last night. It seems like 6500k does have a red spectrum, but obviously not as high as a 2800 or 3000k.

Im sure you'd get really nice buds, Pretty sure there are a few flowering under 5000K on here. Try it and report back. Or yea do what you just posted mix them up.

I use both 2700k and 6400k spectrum for flowering. I am on my first grow so I don't have any results. But week 4 into flowering and my plants look good!

My link shows a mix of bulbs. My first run with my t5 was all 6500 bulbs. It yielded a little less but was great smoke.

Check out the member RM3 threads.

It is best to use a mixed spectrum.

I have added 10,000k and uva to mine as well.

I use pure par bulbs to. They are purple from the mix of red and blue.

You can get a good t5ho for little over a c note.
