Non-co2 Tank; Do I Need To Go All Out?

Hi there!

I have a 37 gallon tank that will be fully planted. It is non CO2, and I'm currently dosing at about a little less than half the recommended dosing for EI due to the tank not being fully planted yet. I'm using the DIY ferts from NilocG, which conveniently combine the macros into one bottle and micros into the other bottle. I'm also trying to prevent algae outbreaks. I've never had algae in a tank before, but I know it's going to most likely happen, so I'm prepared for it :)

My question is; How much light should I be going for? I'm sticking to easy plants that don't necessarily require a lot of light, but I wanted a decent light to go overtop. I'm looking at either the Finnex Planted+ 24/7 Light or Beamswork DA FSPEC LED Light Freshwater 0.50W. Either or, the light will be on a timer (stuck between 6 or 8 hours at the moment, not sure which would be better to reduce algae yet provide enough light).

Would either of these be 'overdoing it' and/or just asking for algae blooms? Should I be sticking with my hood light?
