Plantera Bulb Farm Problem

[sewerpvnk]

I created a Plantera Bulb farm, but no Plantera Bulbs have spawned. I used jungle grass seeds and mud, yet I waited two REAL LIFE days and still no bulbs. Can anyone help me with this?

Made sure you are in hardmode and have defeated the three mech bosses?

It needs to be counted as CAVERNS, not "Underground".

From http://terraria.gamepedia.com/Plantera%27s_Bulb

"Bulb placement is partially random, but they do spawn at somewhat regular intervals of roughly 150-300 tiles from each other. The more Underground Jungle a world contains, the more Bulbs will spawn. They do not require Underground Jungle between them, so small areas of Underground Jungle at least 300 tiles away from each other will each eventually spawn Bulbs."

Plus
"They spawn one at a time after a delay of about half a day between them"

Here is an example image of Plantera bulb spawns.

Bulbs spawn in both the underground and cavern layers.
