i have to agree with this approach. i grew a plant from bagseed for a month indoors only using the local garden center soil and a couple CFLs, then transplanted to the outdoors. I added a little bit of all purpose fertilizer, sprayed with neem once in a while, and ended up with a 7 foot plant with good buds at the end of the season. (only problem was the seed i used came from jamaican buds, and since I grew it in VT the season was disappointingly short. given another month, the buds would have been massive.)
