I have had success with ILGM Gold Leaf with three plants: two under cheap LED lights in a tent, and one that grew into a monster outdoors in the lower Midwest. I planted it right after the last frost in late April and harvested it yesterday, 09/24.
Great info mate, always good to hear methods and reasonings behind using (or not using) things like air-con. Definitely kills the humidity! Looking lovely too, as always. Cheers!
