I would let them both go and hope they make lots of seeds so you can plant more next time. I wish i would have done that this last time anyway...never paying $70 for seeds again.
man lr2 is a pretty cool strain. so it will auto flower with 18/6 through the whole growth cycle.. i saw some pics of other lr2s and it looks like it yeilds quit a bit considering it doesnt seem to grow very tall!! is it 100% indica?
