Thank you so much for your input. This stuff has really been making my brain work overtime!

I will have a fixed ratio array, but at the same time I will have two led lights.

The only reason I was going to tinker with the all blue veg light is because others who have say that it takes away a lot of the stretch, and the plants still veg just fine. (So they say...I haven't personally tested this)

Trying to find the missing link here is fun. Assuming that the light is the only variable in the equation, what is it that HPS provides that LED is missing? We know from studies which wavelengths are the most beneficial. I bet the far-red is the key. Only time will tell.

So you think 5:1 is the optimal ratio?

Should I split up the blues in the "red" panel using two wavelengths? If so which nm blues should I use?

I like testing the unknown. Collectively, with many people here the most efficient and productive way within our current limits can be found.:thumbsup:
