You do see some freaky tight uniform nugs sometimes….I tend to avoid them…

bud density more related to strain and growing conditions in my experience.

If I wanted to maximise cost per square foot, I'd go with high yielding strain and do some plant training with nets and plant ties 😂

Natural pgrs are fine. Just not the synthetic ones;)

The high from pgr weed feels regulated to some degree in that it has a limit of potency irrespective of thc content. Solely for aesthetics.

Fluffy buds are natural as its a plant. If you want tighter buds, get better lighting, conditions etc.

You can get organic bud boosters which is just carbs & food to make bigger more tighter buds, it don't have to be chemical
