If this is your first grow, I would grow 2... yes I said it.,,,,,,, ONLY 2 plants...

They will be amazing... giving you about 2-4 ounces each,,,, under a 600watt HPS..

Keep the light close to the tops of your (mature) plants ( 3-8 inches) and have a fan blow between you plants and your light. An inexpensive bubler system would be perfect using clay rocks..

Veg until they are 12-16 inches... take clones- let the plants grow for 7-10 more days and flower the suckers...

YOU WILL BE BLOWN away....

good luck!! : )
