I use the dry starting at wk 5 @ 2 tsp. The stuff is an instant fattner, the next day they swell up. the only thing I notice is they really make them quiet down on the smell which is a great thing IMO. It all comes back by the time its lit up, thats where they call it loud! I use the liquid the entire flowering period, wk 1-4 its 2 tsp 5-7 3 tsp 8 back to 2 tsp. Dry KB really helped my Kushberry cause thats a very low yeilder and I grew 1 wk clones so I needed all the help I could get! They still aint huge but they hard as a rock.
