Dense buds? Help

[Newbie5648]

I've ran my 2nf grow now. Better than the first.
Don't know what I'm doing wrong as I believe I could have much more dense a fat colas.
Ran Green gelato auto by rqs.
In fabric pot in a single cupboard grow.
Amazon 600W wakyme blurple grow light and biobizz nutrs along with guanokalong.
Small fan blowing. That's all I think.
Am I missing anything? Buds are more airy than packed and dense.
Advice anyone?

I ran a haze strain that looks like that,,,then a sour lowrider next and totally different,denser for sure,still all good tho,just disappears quicker fluffy

I found that genetics is the main contributor to bud density. I grew a lot of autoflowers...very few ever had true density..to many variables when you add ruderalis genetics to the mix. But of course there is always outliers...they are just few and further in-between. The second thing is the type of light your using. Once I switched to quantum boards, I got buds hard as rock

i have compressed some budz by hand,,rolling a little before putting them into the dry box to hang,,there was a diff.

@JJ me too with silver shining haze..I think sativa dominant strains have lighter and less dense buds from what I've seen and read. My white widow on the other hand, massive buds..grow side by side with the haze

It's definitely got something to do with strain. I grow under a invis 4r and a ish150br. The bud quality definitely increased after I swapped to these from the cheap spider farm blurple copy I used

Also I noticed in summer they went more towards fluffy too but my temps and rh went a bit crazy last year
