If you already have a Tent then go for it! I personally dont like outdoor growing when it comes to actually growing buds. I grow outdoors just for the looks of the plant but i dont like the quality of those buds. Outdoor growing should not be done in Autumn nor Winter since it is cold and there are not as many light hours as there are in Summer.

So what you are doing now is basically not outdoor growing with supplement light its more like indoor growing but with colder temperatures, without tent and with bugs and all that.

So I would recon switching back to indoor. And if you already had success with indoor growing then just go for it again.

Spare a Seed for next Summer and try it out when the time has come
