I grew some romulan x afgoo this last outdoor season. I still have one plant outside now, i started roughly 25. Due to some circumstances my outdoor grow did not go as planned so I dont think I can really give you too much info about the strain because I was not able to grow it how i would have liked to. Also mine were in soil.
Anyways they were kind of sensitive to nutes, i couple of them burned up and died early on. I topped and fimmed them and they did pretty good. Sorry i kind of los my train of thought. Its a nice strain, goodluck. Let me know if you have any specific questions i may be able to answer
