It's spring, temperatures are climbing and the sun is bright, must be time to change the 1000W artificial star in the basement.
This year I'm breaking from my normal mid spectrum economical MH bulb and trying a Sunmaster warm spectrum. Let me tell you it is definately warmer, much more red but the spectrum still shows plenty of blues, as a matter of fact, I now realize that some of my plants have yellow in them, a color I couldn't see under the old bulb. On the downside most of the energy is still wasted in the mid ranges where beta-caronine works, this must be to make the human observers happy. Anyone know if Neps make use of Caratanoids?
Anyway my intent is to get a bit more stem elongation on my N. Spec and a few others that really have some close packed nodes and perhaps get my three foot tall N. Miranda to shoot up a flower.
Back to the question. I've always used the normal MHs and have been happy but curiosity must one day kill me, so has anyone tried these warm spectrum tubes and what effects have you seen in growth. Neps, I know you also use MH bulbs, what is your experience?
Last question, anyone ever tried the high K cool bulbs? Perhaps I wil try one next year if I don't care for the warm bulb.
