My buds are great but not hard

Hello I am Will Ive been growing a few years. i just harvest three Gelato girl Harvest is great buds are lovely I got 13 oz out of them off the charts. But what I notices about my buds they are never hard and dense why my friends love the way they look and smoke but we wonder why not hard? can you help?

Not enough light some say temperature also factors in and some say you just need extra red light and I have to agree the rspec hlg lights made some seriously dense buds for my 1st time


I am using a 1000 watt HPS with hood

Light def isn’t the issue then as long as your bulbs are good and your heights and everything are good how have your temps been like stated above high temps and certain genetics won’t allow for rock solid nugs

How old is your bulb?
