that's the growing environment I set for my plumerias. base on my lux meter reading. it's from 24k lux to 38k lux around the plants(the brightest sunlight is 120k lux) . the growing tip receives 24k lux and the leaves receive 30k+ lux. I have these grow light on for 16 hours everyday. grow light is on a timer to turn on/off itself. temperature between grow light and leaves is 30C degree. night time drop to 20C degree when grow light is off. I have two 12cm pc fan above the plants for ventilation. humidity level is between 40% to 80%+. when the light is on it's between 40% to 56% I spray the leaves and other plants at grow tent twice to three time a day. when grow light is off, grow tent humidity goes above 70%. that's the growing environment I set for my plumeria obtusa cultivar singapore white and singapore pink. let's see how my plumeria react to it.
