Dense buds

I did some research on ways to fill-in or put some more size and density to my buds. A lot of what I found was simple basic level information with some variations.

Things like: keeping temps below 85F, controlling humidity, CO2, airflow...

But a few things stuck out to me:
Reducing the humidity below 45% in the last 2-3 weeks can increase the density in the buds. This was interesting since the logic behind this technique correlates with the natural seasonal cycles. The later summer humidity tends to dip in most areas.

Some growers use a type of drip feed system, like BluMats, where there is always a reservoir filled with nutrients. With systems like these or similar hydroponic systems there can be a build-up of algae within the system. Algae will eat the foods that some bacterias eat, but also prevents larvae from forming since there is no food sources. Using Enzyme Komplete Natural cleaner can help with this. This product can actually eat the algae in the system. So later in flowering this can have a huge impact on the final feedings and flush.

Question: In regards to Nitrogen use in flower. From what i read and know, Nitrogen can effect the density of the final product. But it is necessary in almost all stages of development. I use Canna nutrients which happens to have a higher Nitrogen level but is a smooth and efficient product. Would changing nutrients in the later stages aid in bud density? Basically using a lower Nitrogen base nutrient, like a straight budding nutrient. I do hand water every 2-3 days with additives and amendments as well as a BluMat system. The BluMats have Canna all the way to last 2-3 weeks, then water for flush. Can Nitrogen really impact density that much?

Thanks.

Lower temps, solid enough light source, proper nutes , proper genetics

Your genetics and even specific phenos within a specific strain will affect your bud density more than anything. Of course proper environment, feeding, etc but if the pheno you're running lacks density find one that is dense, anything else may have slight effects but won't change airy buds into dense buds.

Last three days I throw the plants in pure darkness no lights whole time, cool temps in there no lights, be careful keep humidity, air flow etc, turn up exuast to maximum.. and no overwater so moisture in there at night too much, bud colors, bud hardness, last push of trichome cold protection layer, top 10 best moves I learned.

you on to something...

(cold=P lockout=colors)
(low RH is dry, hard. no fluffy in high rh moist mold shit style conditions.)
(cold is tighter denser suck in like shivering, compared hot fluffy spread out to stay cool)

-huge mold risk if enviro not perfect!!!

Your lighting above all else will be the master determination in how dense your buds are. Everything after that is simply keeping up with how intense your lights are. Figuring out how close you can get your lights to your canopy without light burning or heat burning is pretty key, I use CO2 to counter my heat more than I use it for dense buds. Simplest way to think about it is your larf is airy because why? no light! And cutting your humidity isn't going to produce "denser" buds, it helps trigger hormones to protect the buds from the dry air so she starts producing resin to better coat those buds.

Genetics: indica dominant strains are known for huge dense buds. Blueberry is known for topping and producing a ton.

Temperature: this also depends on genetics. If you know the origin of your strain you can imitate its environment.

Humidity: mold, fungus and bud rot are attributed to high relative humidity. On the opposing side, too low relative humidity will cause stunted growth as the stomata won't open.

Lighting: regardless of the type of light system being used a rule of thumb is one-hundred to two-hundred mols of light photons per square foot. Also, positioning of lighting is very important. Check out some of the vertical grows on here, that is a style I'll be incorporating myself when I get built up in my new place.

Nutrition: steer clear of General Hydroponics and Bontanicare. Check out Roots Organic, Oregon based and family owned.

Mediums: organic soil grows have a taste and smell synthetic hydroponics can't compete with, as well as soil cannot compete with the weight hydroponics can offer. Hydroponics is much more complicated.

If you have any other questions I'm sure someone has asked them before and someone else has answered them in a thread on this site, Grasscity or CannabisCulture.

Just use only PGR's. Lol

Light light light and more light.
