Hi Dudegrows – I’m using a nanolux 630w double bulb lamp with Ushio CMH-315w/930/ AGRO 315w ceramic bulbs in a 5 x 5 gorilla grow tent. The plants are 41/2 – 5 feet away from the light. The temperature is between 80-85 degrees and humidity is between 40-50%. The result is burning and waxing of the leaves in some of the plants. Any advice to keep the leaves from burning?
