I cut their recommendations in half, so I use 1/8 tsp per gal week 5, 1/4 tsp per gal weeks 6-8, then 1/2 tsp per gallon weeks 9 & 10. GH also has their nutrient charts on their web site, if you prefer to see their feeding schedules. Hope this helps. **Q: ... Ive heard this Increases the smell of buds immensly ... is this true ??? ... I luv the smells produced and would like to increase the smell and a** A: this will increase the size and potence of the bud bulkening it up i find the smell to be the same with or without a good product i use it always every flower it is part of my feeding schedule ## Customer Reviews ### ⭐⭐⭐⭐⭐ This does the trick *by W***M on May 16, 2026* General Hydroponics is your one stop for nutrients.
