Depends......if you want live plants you will not want the LED
lighting you will want good fluorescent lights or very...very expensive LED
's rated for growing (i had no luck with the stock LED
I bought the 29g LED
KIT and hated the lighting and the hood seems very cheap... its a small LED
fixture (about 8 inches long not full across the tank) that didn't light the tank up the way i wanted it to or the way it should of. it had dark spots in the top corners.
I do however like the BIO wheel and the heater you get but i went and bought a Glass top and the Aqueon T5 light fixture has a white all spectrum light and a colormax light in it seems great for plants and for bringing color out.
I don't know anything about the cube just LED
lighting won't grow plants very good.....well starter kit LEDs will not.
But i am very happy with my 29g after i bought the glass top and new lights
but if all you are looking for is an aquarium and not worried about plants and what not....the cube looks nice i think..also has the double bright LED
which i would think is better than the 29gal tiny light fixture .and the cube has a stand for a decent price....I actually built my own stand for my 29g
