Humbolt gravity review?

Ok so anyone ever used this stuff. It says it a bud harder. I know they don't make it anymore but it's pretty easy to get some. I just always get airy buds. And if it's my temps then I don't know since my house stays at 80f so my grow room sits around 85f...

It's contains Paclobatruzal which is known to have carciniginic properties. Not worth it IMO.

What about Mendocino avalanche

Yup I use Mendo Avalanche its the only registered company that is allowed to make the claim flower hardener. Works great keeps the buds solid even after drying also the smaller popcorn nugs stay dense as well but its also strain dependent it won't make a non dense bud into a dense bud, 2ml/gal starting week 2 of flower then gradually to 5 ml/gal by week 7.
