Not sure if this is where i should post this...

But Trees will not grow under Wrath Lamps, even with bonemeal.

I had Wrath Lamps set up 30 blocks above my base, so it would light up even during the night to stop monsters outside my door. Everything was fine, till I tried to grow a tree.

First a Silverwood Sappling wouldn't grow, I even waited 72 hours. Then I tried it with a Hoe of Growth, still nothing.
Then I tried a Oak sappling. Waited 4 hours and it wouldn't grow. Tried Bonemeal, still nothing.
After I moved them out from under the wrath lamp, everything worked fine. Both the Silverwood and the Oak grew instantly with Bonemeal/Hoe of Growth.

I took down the Wrath lamp, and after a few server restarts to fix the lighting issue (The light stayed even though the Wrath Lamp was gone) everything works fine in the original location I was trying to grow the trees.

Known issue ever since Factorization was added to FTB back in 2012.

Wrath Lamps work by filling the vicinity with invisible blocks that emit light. These blocks are detected by plants trying to grow as obstructions, and therefore they think they can't grow.
