Seedlings - Light question.

Yes I'm sorry I'm new to this.

I'm growing from seed. I need to purchase the light for the seedlings in the Grow tent. We are growing legal medical. I was going to purchase a Hydrofarm or sun blaze T5 HO for the grow tent 4 ft 4 bulbs with two switches for 2 or 4 bulb operation. We will be growing more plants than for personal use.

our Veg = MH
Our Flowering - HPS

AM I on the right track here. Please remember we are looking to grow at optimal speeds to provide for patients.

Thank you,
