Very satisfied considering the tent does it owns thing. No fans running, door sometimes left open to let hot air out...I have been leaving a window open to cool the tent down, bringing the relative humidity. I think calcium is lacking in the female plant. I recently top dressed with worm casting, seasoil, promix and gaig green 2-8-4. The pots are sitting on a lid directly on the ground. Floor gets colder in wintertime in Alberta.
