HI;

In just 4 days of growing under lights I have had a grey mold show up on many of my plants. I searched and found this is quite common. I'm around 40-50% RH and about 70 degrees.

I had the furnace constantly circulating air into the room, but not blowing directly on the plants, I thought that would be enough air movement.

I am going to add a fan in the morning.

Do I need to do anything to treat the small amounts of mold I am currently seeing or should I just increase the air flow first with the fan and then see what happens.

Thanks

Jamie
