# Parallel circuits question

I am trying to make an LED grow light and I have an electrical question. I want a simple light grid, but I am not sure on the math. I understand how to calculate a the resistor needed for a series circuit with a power source and several LEDs, but I do not grok the math for parallel circuits. Can all of the parallel series equal the total voltage? Do I just add the amps from all of the LEDs to figure how many series I can run parallel? Or am I completely off track? Thanks for the help!
