Bud Hardener? Nftg

[Gratefulmeds]

I recently had a friend tell me I need to get a bud hardener.. he's deff not a pro, and I've seen buds tighten up nice with my nftg feeding schedule outside, but I've never used nftg inside. Any thoughts? Back when I was just getting stared I used gravity on my indoor garden but have heard negative things since.. any ideas trying to keep my ladies organic as possible ty

I use molasses to give weight not necessarily hardener...near the end i lower temp and they naturally tend to harden up.
