outdoor to indoor

Grown outdoor, but have new construction going on and changed to indoor, my knowledge is not as great, but choose CFL Lighting and am totally amazed, plants are in their fourth week, and it looks like 4 inch tall bushes and 6 to 8 inch wide and more growth than l have ever seen growing outdoors. What Am I Doing RIGHT, Using my standard vegetable fertilizer, 18 hours on - 6 off, potting soil dirt, give me a shout if you know

Indoors, its always a better start, as the plants are short and close to light, with 18 hours of light on them. As they grow, the light penetration slowly degrades, especially with CFLs, unless you train them and SoG. Anyhow, the final result will be around 0.5-1.0 g/watt, so you are limited with your lights.

Outdoor plants boost once they grow tall and have huge leaves, that's when you see the real power of sun

SoG !!!
