indoor insolation...can not be accomplished unless you put something that will keep the pollen from "floating" to the next plant...this is, of course, my opinion...
outdoors...1 mile is good rule of thumb...you have to take into consideration how far bee's fly...
Thanks Jack
Obviously the goal would be to grow several varieties while preserving the strains.....
Indoor would be easier as I have three floors
Can any kind of netting be used outside to prevent insect pollination?
