From a fellow grower:
I attempted to grow 2 auto flower plants using a single 75 LED light in an enclosed room. Although conscious of the temp, humidity, lighting and water, the size and quantity of the grow leaves a lot to be desired.
Strain: Blue Dream
Type: Auto Flower
Medium: Pot for Pot Superb Soil/Kit
Light Type: 75 watt LED from Pot for Pot
Light Schedule: 18 hours on/6 hours off
Temperature: (consistent day/night) 72°
Humidity: (consistent day/night) 49
Ventilation: Consistent forced air room circulation
Seedlings planted: 10/15
Please see pic attached. As of 12/9 plants have been moved to a grow tent. A new 4 x 4 LED 150 watt with dimmer is on the way.
Plants just seem to be struggling. Unfortunately I added additional nutrients to the one plant to see if it would help, and now the leaves are burning up.
