>>1021840They only give the antler form if you raise CO2. Bags are better for manipulating form.
Outdoors you will always get conk form, indoors you can manipulate CO2 levels to change the form, as well as rotate the bags. High CO2 initiates antler formation and branching, low CO2 initiates conk formation. There is a whole japanese/chinese methodology based on getting them to grow into different forms. Some people claim the antlers are more potent.
