Root-Like Growth on Pepper Stems: Drainage Issue

White nubs on pepper stem above soil = adventitious roots from buried stem contact, or mold from poor drainage. Coffee cans need bottom holes + gravel layer. Peppers don't root from stems like tomatoes.

Fix

Drill holes in can bottoms.
Add 1" gravel/sand.
Use well-draining potting mix.
Don't bury stem—peppers rot.

Drainage solves both rooting and mold.
