Thank youif plants get less than 8 hours of light, they tend to take on a winter form, so leave shapes are different, and more confined, I personally aim for 12-14, and samp lights up/down and dim appropriately to avoid algae,.
The better and more plants are growing, the less nutrients there will be for any algae.
I will get the timer 0.0it can be on substrate, and in the water, and in certain circumstances with certain plants and cyanobacteria kind of toxic too.
and lets say you should buy a damn timer!!!!!
