GetThisOrDie Reviewed by GetThisOrDie on . balcony on the equater, getting started Hi all, I just signed up and searched the forums before posting. I have the following environment: 19th floor apartment, big balcony, 75-85F, 40% humidity, 12 hours of light and 12 hours of darkness all year round. Light cycle from 5am to 5pm. Balcony faces the east and receives good light from 6-9am, decent indirect light after that. Powerful lites are on the balcony that could be strong enough to add more light time. Gets moderately windy. Rains hard in march and april. Very sunny beyond Rating: 5
