Very tricky questions...does he already have a 1000HPS light?...but not the CFL's?..a 400 or 600HPS would be better.

You CAN veg under HPS too. Generally, you veg the plants for about 30+ days, until the plants are 12-15 inches tall. But everyone says veg under 6500k cool white CFL's (I never tried it)

Now comes the hard part...HEAT. Test the grow room temps..BEFORE you pop the seeds. Get a battery thermometer, one that records high/low temps and humidity. The objective is to keep the temp at the top of the plants at 75-85 degrees and around 50% humidity. It's not easy. 3x2 is very small for 1K light. Most people that do this alot, use A/C and have good air flow.

There are many, many other issues to go over. A grow guide will cover this. There a several available on this site.
