Sounds like you will have until about the first week of october.. This is good enough to get an ounce off of a vigorous indica which it sounds like you have. So you just want to germinate and follow same steps as you do indoors. Just make sure you put in a pot of good soil instead of the ground. Make sure you place somewhere the plants get as much daylight as possible and place protection against rodents around your babies..
You will probably get somewhere close to about an ounce for each female. Happy growing!!!:stoned:
