Full blast or half power?

[Sativaindica]

I basically just made sure extension cords and power strips were new or in good shape and grounded as well. Got my two big lights on one power strip going to my timer. Wondering if the four small lights can go on another power strip then plugged into the other side of the timer or if I should get a second timer and run those to a separate outlet. The pump and fans are together on one power strip. Hopefully I’m good but I better study ohms law lol.
