yea but i see in your picture your using HID i understand for veg but i want to get the most out of the plant what you think of 600w hps?

100w will litteraly do nothing. Buy an 8 bulb T5 fixture. Use Veg bulbs (blue spectrum) to grow the plants and then when it's time to flower use the Bloom/Flower bulbs (red spectrum). I can outgrow my buddy using t5's and he as a 400w HPS. That t5 fixture will only add $50 to your bill.
