microkrunk, i am on my second lowryder2 grow and have had great success with leaving lights on 24 hours during entire grow. Started seedlings under cfls and after about 1 week moved into grow cabinet under 400w hps and have had amazing results. Mostly using these plants for bubblehash and green dragon. They are prolific seed producers, and since seeds are a little $$$$$$. You must pollinate. This is just my humble stoner opinion. Remember these are an autoflower strain which means there is no vegetative stage. Dont be fooled!!! They will flower regardless of light regamine.
