Thank you! I may be having one of my boys pick some bulbs up for me, then. :D
Found it!
This is showing $23/bulb, any way to make a little more savings on that? Also, the graphs you posted are showing two HPS bulbs, but I thought you said you're using the MH. Am I confused? It's not unheard of.
So I have this tree I am growing and it is surrounded by (4) 1000w bulbs.
2 MH and 2 HPS.
Plant tissue (leaves) being pummeled with HPS light are showing what looks like a P deficiency (brown spotting, purple petioles etc)
Leaves hit my the MH do not show these symptoms. This is on the same plant.
So by this observation I am wondering if an HPS spectrum (more red?) causes the plant to take up more P...
Where the botanists at yo!? I am super curious about this.
The spectrum of the hps is designed to encourage flowering and the plants use more floragen hormone at which time the P and Ca demands amongst other things will increase. So, I think the answer is yes.
cap, have you done a test drive with dual arcs?
clockworx, same question?
I'm trying the 247 garden version and it seems to keep my plants VERY happy through to the end. only after a good seven to ten day flush do i see a big change to the more typical browns and yellows starting in on the leaves.

Plants need red light to fully metabolize P. I switched to CMH bulbs for veg which give off a more balanced spectrum (lots more red than MH) and am never looking back. Cap noted better root production under a warmer light. I've definitely shaved days off my cloning schedule since introducing red light.
