I keep several plant tanks, three have AH Supply lights and are CO2 injected. I have one crypts
tank which is a 20L with 2 15w bulbs on it, this may be upgrade to a 2 20w set-up.
Then I have two other tanks used for cultivating plants. One is a 55 with 2 40w Trichromatics,
the other 20L with 2 20w fluorescent bulbs.
