lighting / plant update
Flourish Excel is different from Flourish. There is a whole line of plant
products under the Flourish name. Regular Flourish (what you have) has
basic nutrients and trace elements. Flourish Excel is supposed to provide
"organic carbon" to the plants, which is why Willis recommended using it
if you aren't using CO2.
Thanks I'll look into Flourish Excel at my work and get some.
