Mold D: Please Help!!!

So I have a closet full of goodies growing under some led's and cfls. The temps. stay around 55-65f, depending day to day. And I have little control of that since my home doesn't have heating. On one of my babies, mold is growing on the soil! Any suggestions on how to kill it?
Thanks in advance everyone!

If its white powder mold, mix 1 tablespoon of baking soda with 1 litre of water, and spray on the mold. To prevent mold again, dont water as much. The lack of heat will slow growing and raise the relative humidity which is perfect for mold. Increasing your ventilation will help too

Hey, thanks man! I will try it next watering!
Awesome, man!

You are watering too much if your soil has mold on it
You should be allowing the medium to completely dry out before watering

and you should really increase the air circulation. If temps are that low buy an inexpensive space heater to warm it up a little. Not too hot though, you only need like 10 more degrees. If you find any mold in the buds (starts in the center and moves out) cut the effected area off with clean scissors and maybe even wearing gloves. make sure not to touch anything that touched the moldy bud to any of the other parts of the plant. and clean your hands and scissors well before touching anything else.
