Bioreactor Entries: Fluffy Puff Seeds (This would be very useful, as you can easily get stacks and stacks of them) https://github.com/SilentChaos512/SilentGems/blob/1.12/common/net/silentchaos512/gems/item/ItemFluffyPuffSeeds.java

Laser Drill Entries: Chaos Essence Ore & Ender Essence Ore (Entries for the gem ores should be a config option if it is added at all, there are dozens of them)
https://github.com/SilentChaos512/SilentGems/blob/1.12/common/net/silentchaos512/gems/block/BlockEssenceOre.java

I'm currently working on adding this with a crafttweaker script, but having official support would be great.

It's all added in 1.7 now.
Do note that I have added Laser Drill entries for every single gem ores and the essence ores, feel free to use CraftTweaker for disabling any entries that you don't want.
