this grow is in an attic I do not have a fan in the window would a window fan or air conditioner be the best for this instance. I have a osscilating fan inside the grow tent but as for the air that is inside the room the air is really not being circulated that great. But as for the yellowing is that a nutrient or air problem I cannot tell as this is my first grow? Also if a fan or ac is needed please tell me I will go out now to get one.
tikigod80 Reviewed by tikigod80 on . If someone can be of some assistance I am in the 6th week and I am at a loss in this grow cycle. At the moment I have a 6 plant eco grower unit with a sylvania 600 watt grow hps bulb I have the homeboxXL and a digital ballast. About 3 days ago I noticed yellowing starting to occur. But before the yellowing had begun the plants were in great health. So far I have done everything in my knowledge to fix the problem. I had talked with various people and they had said overewatering but isn't that impossible with the system I am using? Rating: 5
