could be really really dense stuff, i get some of that sometimes - 7 grams can be pretty disappointing when the volume is comparable to 3.5 of heads. Plus, seeds i think are more dense than weed. Thus, lots of seeds, lots of weight without lots of volume.

for 40 though, I'm guessing you don't live in cali but thats not terrible by some standards - assuming the shit's at least a little potent
