Hatch-Rite..best place to buy?

[Mike41793]

That's not what the OP was asking. But anyway, Hatchrite is not perlite, you can reuse it indefinitely, and it's fool proof.

Yes it is, it's glorified perlite, as nikki said. It's just foolproof premixed perlite lol

EDIT: ok maybe not foolproof... But its dumbed down.
