I'm new to this forum- usually in the aroid or carnivorous plant forums. But now that I have an interest in broms, can someone please explain what "growing hard" is, and which plants benefit from it?
Grown with no fertilizer. The colorful Neoregelias and spotted Billbergias benefit most.

What Gonz said is the way I have interpreted the meaning also; plus leaving to the elements with no added artificial protection such as shade cloth, fibre glass etc.
All the best, Nev.
