Counselor...

I appreciate the discussion. And your Lucagrow light is indeed a 'dual spectrum' light. I dont know if thats the same technical terms as a Hortilux bulb or not.

I too run a dual spectrum system...I have a 250W MH and a 500W HPS....

I use neither in veg, but both in flower. So if this is the same content of the lucagrow or even the Hortilux, we are acheiving the same thing, just different methods.

I use two bulbs and you guys use one

But I just know its true that flowering tomato plants need HPS red far more than MH Blue....

I add the blue for the UV-B rays only.....but do so maintaining an HPS dominance of 2:1.

I will do some research this weekend on these bulbs. Hell if I can find Hortilux with a 2:1 HPS ratio, I'll buy two of them to use....that would be fricking killer

BUt I'd only use them in flower

Thanks again and I am sure your skill in your grow system deserves far more credit than your light bulbs.....again a nice awesum grow. Really !
