just because you had a successful grow in a 6" pot doesnt mean its the best way to go about it.. You should really go through and read alot of the sticky's in these forums before you start again. I'm a first time grower myself, although im growing outside, the same concepts still applies ie. (transplanting properly, watching nutrient levels, etc.)
When i started here i was told to read up on stinkyattic's posts and indeed i did, she has a gazillion posts on how to get the most from your plants.
Optomizing your grow would be a great way to go, having just one plant isnt always reliable (could turn male, could be retarded genetics etc.) Your lighting setup seems optimal for a micro grow (up to 6-7 plants depending on space).
Just remember, if you fail -- go back read more, and when you think you've read enough, read some more, and then try again .
Also, fox farm soil isnt necessary for a good grow, im using a compost/potting mix that cost me $1.80 per cubic foot. With a good set of nutrients, you can get everything you need out of your plant.
And again, read read read, everything you need from start to finish is inside this forum.
Cheers! TK.
