T8 Grow Lights

[denialisback]

that should work for what I am doing. I will supplement with CFLs soon. Also it's kind of weird but the lights have a purple glow. They are not black lights or ultraviolet though.

heh yeah i believe it if its showing purple "spectra". makes sense because 2200 daylight white/blue + 7700 flower red spectra = purple..

i.e. prime red + prime blue = mid spectra purple i.e. 4000-5000k

I only just noticed this so feeling proud Good info bigleague, and goodluck!

It's worth noting that the prime red+ blue won't work with lights heh due to quantum superposition effects differing (wave vs particle).. but it still stands that mid spectra between 2200k 7700k is 4000-5000, so this makes sense to me!


Am i going cras?

denialisback Reviewed by denialisback on 03-21-2009. T8 Grow Lights So recently I started an indoor grow box. I have germinated a bag seed and set up two T8 Fluorescent 18 watt 22 in. grow light tubes. Does anyone know anything about these? Will they work ok for growing. I'm gonna set up some CFls for when the plant gets bigger but for the early stages are these ok or do I need to rush in the CFL power? I have found barely any good information about these lights online. The box does not even say what K they are or how many lumens. I got them at lowes and the Rating: 5
