An update and another question.
Pretty much I let them grow freely outside, with occassional watering in the morning. Soon it developed some spider mites problem but I think the plants still lives. At this point, they are around 14" to 16", not much changed in heights, but the leaves and branches seems to bloom a bit.

My question is, I'm thinking about chopping them down and start a new batch of seeds (instead of clones). But it seems the plants still growing with new leaves, even thou the flowers already turned brown. Should I start to harvest them, leave the new grown leaves on the main stems, repot, and just them reveg?
