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.

He is using an E&F system for 10 plants. He doesn't have internet access and wanted a few questions answered: 1) How many 100W CFLs would be sufficient for 10 plants to veg under? 2) How long should they stay under the CFLs before switching to his 1KW HPS light so they don't burn? 3) Would putting the squirrel fan intake under the hood (but not like a cool tube, just put it under the Rating: 5
