I wouldn't put her in the ground yet. In my opinion you want a bigger root system for outdoors in the ground. I would transplant it into a gallon pot and let her build up roots and grow bigger and stronger. I don't know where you live but you should have at least 14hrs of daylight and descent temps. That's just my opinion others may tell you different. Best of luck with your grow.
If you live in canada. Earliest I've put them in the ground was may 24th long weekend but we still got cold days and it messed em up. I wait until the first weekend in June and they still get massive. I've put some out at the end of June that got just as big as.the earlier ones except the nodes were spaced out more so I got abit less but not much
