Hi,
I am buying a 32g this weekend and it comes with a 2 bulb fixture, the two bulbs it comes with are 20w each, 4100k and a 18000k. Is this ok for growing plants? I'm doing non-co2 and have low light plants so I'm not looking for a setup that produces fast growth, just something that will keep them happy and alive and I don't want the algae to build up too much.
