Isnt that what I did here?
ItemStack output = new ItemStack(Skybees.editedFrame);
NBTTagCompound tag = output.getTagCompound();
if (tag == null) {
tag = new NBTTagCompound();
output.setTagCompound(tag);
}
tag.setFloat("floweringModifer", flowering);
tag.setFloat("lifespanModifer", lifespan);
tag.setFloat("mutationModifier", mutation);
tag.setFloat("territoryModifer", production);
tag.setFloat("productionModifer", territory);
