10 WW, lights and pot size

A question from a fellow grower:

what lights do you recommend for 10 white widow plants, and what size pot should they be transplanted to

I am growing 12 WW now. I have them in 2 1/2 gallon pots and am using 2 350 W led’s. There are Advanced Led Lights and I can saturate an area of 3 feet X 12 Feet. I have good penetration down into the plants. These lights are kind of pricey but I like them. For me, they do the job.
