Ok so I just picked up a 120... A little bit bigger than my current 30. I have some wood and stone to put in it but I also want some plants. I plan on building a canopy with 4 Ustellar 60W LED Flood 4800lm, 5000K Daylight White which would put me at 2w per gallon. I want to keep it kind of on the low maintenance side I would like suggestions on substrate and plants. I have no plans to dose ferts or co2. Thanks for the help.
