Hurry as fast as possible to your grow shop, or be ready to pay for some overnight shipping, and buy some Mad Farmer Mother Of All Blooms And molasis but the mother of all blooms is more important. I think its to late for super dense buds but this will definitely increase density.

I got some for free because my local grow shop was giving away free samples. They gave me 4 bags, each bag had maybe 16 tablespoons. (they gave me a lot) I used it on on 50% of my crop. ( I have 2 reservoirs) It was definitely evident that the nugs were much denser and weighed 20% more.

I was using GH and sweeth a Ph pH of 5.85
