What to do

I have a blackberry by Sativa seed bank that has me perplexed. She has been under 12/12 for 2 months and if there are any flowers you can only see with a magnifying glass. My question is, can I just put her outdoors and let nature take it's course? or is it too late for that..... about ready to give up with this one. All my other strains look super good.... first frost is still 3 months away.

If you have the space I'd just keep it running.
No nanners or did it get possibly seeded?

Nope, no nanners...all by her self. My past indoor grows have all been good but this thing is so slow and HUGE!
