Why not a hybrid type of a grow? Outside during the day, and bring them in for evening light, and longer vegging. I've been doing this with four plants as a 'controlled experiment' with eight plants exclusively inside.

The outside plants, after seven weeks are a full ten inches taller with much a much healthier set of lower branches. The indoor plants are under an eight lamp bank of blue T5 floro's, with 65w cfl's on the sides...
