thnks for all the advice i switched my plants to 18/6 yesterday an i kinda see a lil bit difference in em ive still got em on the schedule ill see how it grows.....how many of you guys use the 20/4?

The best cycle of them all is 20/4....Its great..someone even runned a test what light schedules are most beneficial, and the 20/4 won...I dont know how true that actualy is( i read that form another site, form an experienced grower) but my veg schedule is on 20/4...works just splendid...
