i don't think there's a better system just diff ways of growing in those sys. No if you use net pots den use pebbles hydrotron/pebbles are the way to go for newbs.
dont you mean switching to a 12/12 light cycle? instead of 18 hours of light only 12? your thread says switching from veg stage to flowering "Bud" stage which involved the light cycle and length of light going from 18/6 to 12/12
