So far so good. All my ladies are looking healthy. No nutes yet. With Fox Farm Ocean Forest they say you dont need to use nutes for the first 3 weeks. Last time I waited about 16 days to start adding them. 600 MH is working good but not producing enough heat. It's been a cold winter in Southern California and I live just a couple of blocks from the ocean which makes it even colder. I put a little space heater by the air intake of my tent and it warms it up very nice inside. Thats it. Check out my other thread...I just posted pics of last Sundays harvest. It was a real winner. Peace.
