Different strains of cannabis plants may need to be grown either indoor or outdoors for the plant to be healthy. Some plants prefer the controlled indoors environment as they are picky on environmental factors, others prefer the sun and complex environment of the great outdoors and some don't care much at all where they are grown. We have put all our seeds into 3 Categories. Those that grow indoors are in one, outdoors in the other and those that grow both indoors and outdoors have their own section. Choose the option in the drop down menu that best suits you and enjoy your seeds!
