Im in FL...I wouldnt grow if you are within Id say 15 miles of the coast...very bad salt content in our air here...again, depending on where you are in FL.....not man options with strains...you described lowrider....only i believe, dont think there are any other short, squat auto-flowering strains....you can keep any strain short for the most part...but almost all ganja strains will be 4ft minimum outside without SERIOUS LST, or topping...eh...grow indoors, or find a spot outside where you can let em go....
