Would two fixtures put me somewhere in the high light range? If so, I am not sure I want to go that route just yet.
It's this type of lighting that was used on my first dirt tank.
Lowes has hanging dual T8 48” 32watt fixtures, silver w/ black end caps for $29.00. I bought two and went with 2-6500K, 2-5000K bulbs labeled as daylight and sunshine.
GE daylight 32w, 2700 lumens, 6500K, cri 78
GE sunshine 32w, 2800 lumens, 5000K, cri 86
2.3 watts per gallon.
Lights set 6 ˝” above the tank and consider it medium but not high light because algae never gave me a great deal of grief.
I know you've seen it but heres the link.
Blast from the past but still here and still wet.
55 gallon Low Tech soil sub grow out tank (56K warning)
Currently the tank has been single fixture with it resting on the top frame for several months and the plants are doin OK.
Thanxs for more pics by the way LOL!
