I tied the lower branches down for 3 days, the bud sites on the end of the branches have doubled in size from the light exposure... I think... A buddy of mine gave me a 1000 watt hps light and dimmable ballast, so I of course threw it in the tent running it at 400 watts because of the heat it produces. Now I need to research ventilation systems... SMH but it's a good problem to have I suppose.
