I think he is trying to describe light and fluffy nugs not shitty compressed weed. newbie22- some plants produce very airy bud which would be very different in texture and density than what you are used to buying.
If that is the case you only have a few options:
1. Light source- most frequently you will hear this when people do CFL grows without enough light they end up with airy and fluffy nugs. Easiest fix get a 1000 HPS-but you are outside so unless you don't have direct sunlight this should not be your issue.
2. Genetics- sometimes you end up with a lady that just does not make dense bud. Apart from using bloom nutes and stuff like that you can't do much about genetics other then breed them out or get a new strain. I have one girl that makes bud that looks dense but it is as squishy as a cotton ball, nothing I can do about it.
3. Harvesting- since you don't have pics there could be potential issues with your harvest times (such as too early), drying schedule (never done paper bag, never done 2 weeks).
All in all if it tastes good and gets you in the right place you should be happy. Don't sit on it or crush it just get a better strain or move indoors with a serious light for flowering.
