Q. Where do I find Chelated micronutrient mix?
A. Homegrown Hydroponics carries a chelated trace element mix.
It is the 6th ingredient in the six pack. Here are details
on its composition:
#6 Chelated Trace element (Fe 7%, B 1.3%, Mn 2%, Zn 0.4%,
Cu 0.1%)
Q. Can
you tell me about the exact Kelvin
rating for the /u/day bulbs.
A. 5500k
when burned in a horizontal position.
Q. I have
heard about you through the aquatic plant newsgroup. I am interested
in obtaining ingredients for the PMDD
(poor man's dosing drop) recipe. The hardest element
to get is the trace
element mix.
A. The
Homegrown nutrient six-pack contains:
#2 K2SO4(potassium sulfate),
#3 KNO3 (potassium nitrate),
#5 MGSO4 (epsom salt),
#6 Chelate Trace element (Fe 7%, B 1.3%, Mn 2%, Zn 0.4%, Cu 0.1%)
- exactly what you want.
Q. I wish
to acquire several 175 watt metal halide units to illuminate a 6
foot X 2 foot freshwater aquarium. I need a source of light which
has a high CRI and a spectrum as closely matched to natural sunlight
as possible. The CRI should be close to 90 or higher and the colour
temperature of the bulbs should be approx. 5,000 ~ 5,500 K. The
lights must be able to be suspended between 15" - 18"
above the water surface (there is not going to be an enclosed hood
over the aquarium). Fluorescent lights are not suitable due to the
fact that I want to suspend the lighting so high over the water
surface and also because the tank is 24 inches deep.
At aquarium shops, most of the MH lighting is meant for marine tanks
and the colour temp. of the bulbs is 10,000 K, which is much too
blue.Additionally, they want well over $1,000.00 for anything which
meets my needs. Someone suggested that I try a hydroponics shop,
which is why I visited your site.
A. Some Hydroponics Shops
carry a 175 Watt Metal Halide with a colour temperature
of 5200K and a CRI of 80. These bulbs can be suspended
from the ceiling so the distance can be adjusted. The bulb is called a 175Watt u/day
bulb. Complete with ballast, reflector and bulb will usually run you around $305. These bulbs are often purchased by aquarium enthusiasts.
