I have a 430 watt HPS light. it's been under the HPS light for the last 55 days.
in the past i've had sucess with skunk/haze, california orange, & bubbleicious.
i've done nothing different . I water the plant with tiger bloom. This is my first white widow.there are two plants in the room about 4X4. one of the plants was a cutting that i put in to make sure it was female, that cutting grew and grew, over 5 feet now. I've never had this many buds on a plant before.
