its way late in the year to have out door seedlings. if you want a decent yield, you should keep them inside in a grow room where you can control the temp, light, nutes, water, etc. im from the south and i usually harvested my outdoor crops around this time. im not tryin to bash you tho bro. if the temp is still high enough the by all means, let em grow. but with the light schedule changing, they will prolly start to flower soon. and on plants that size you wont get alot of bud from em.
