I was referring to the flowering light. I should have been more specific. I want to have a seperate light for veg. But should I still put in some 430nm blues along with the 452nm blues in the flowering light?
I'm running at 4:1 in the bloomery trying to limit stretch.



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

So, whuddaya think?

I'm thinkin I need to peg the 430 and 452 in the blue light. But more 452 than 430. But does the plant use any red light at all for the veg stage? From the research I've done it's mostly the blues that contribute to the growth in that period.

It's nice to discuss this with someone....so far it's been all solo for me. I completely followed your thread with the build of the light, but when looking at the cost to do it that way with the 15W'ers, it was more cost effective my way. Though I won't get the flexibility that you have. Give and take right?

On the funnier side of things...just read this. It might be old but a new one to me:

There once was a bud named B.C.
He grew on a 7 foot tree
Till one day I plucked him
Rolled him & smoked him
And now I can barely see! :jointsmile:
