How do you get rock hard budsites?

molasses
 
 
dissolve 1 tbsp in a gallon of pure water 24 hours prior to watering, dispose of any left over, repeat for each watering until you harvest...do not use any other nutes

 

genetics. some strains are fluffy and foxtail normally these are sativa indica have very dense nuggets

 

yea strain, food, and light..most sativa ive went was 50/50 and even those were pretty hard...sometimes real dense isnt good though cause they can mold so watch your humidity and have good airflow

 

 
i assumed using organic soil...and flushing period..it can work in hydro but you have to chill the water and keep it recycling so it doesn't go bad...it can ferment if contaminated killing the plants (it is 'sugar' aka hydrocarbons after all)
 
they have other feeding methods you can look up to match your type of media...use google for more info and to verify

 

I use unsulphured Grandma's Molasses and it works pretty damn good bro...

 

any sugar works, but mollases is king.
beyond ginetics, lighting has the largest impact on density
heat comes next, the higher heat you have the fluffier your nugs will be. generally
nutes have a large impact as well, think about it, a nug is comprised of 60-70% water, 10-20% hard metals and "nutes" and the remainder is basically sugar compounds.
(this is while nugs are still growing)
you flush to remove the 10-20% of hard metals
then you add mollases to increase the amount of sugars.
when you chop the plant you dry the water out and are left with sugars.
then once you go to cure, the sugars should, in theory, assist in the decomposition and breaking down of the remainder of the metals and clorophyll left in the nugs. (i.e. improving the flavor)
blah blah blah, im sure you get the point.
 

 

I've heard kelp extract works, but I have no experience with it.  Maybe you can try mixing Viagra with your feed water.
