Mold plezzz help

so i was having a few problems about a week / week & 1/2 ago ,, & i solved it by moving my lights up higher & i flushed on the 7th mm today the 13th the top of the soil is still nice & moist ,, & i just noticed a lil piece of MOLD ,, on a piece of dirt ,, i seen the lil fuzz growing ,, so i took that piece out of teh pot ,, my question is ,, what kills mold ?? any household items i can use ..??? i guess i will also keep my lil fan on teh soil 24/7

adding H2O2 to your water will kill that. 30ml to a gallon.

I learned the hard way,the best investment you could ever make is on oscalating fans in every corner of your room to keep air flowing,i had mildew & mold problems at the start,having fans in all corners with each fan set at a different level keeps the entire room circulated with fresh air.

4 oscalating fans from Family dollar cost about $60.

Plus add the peroxide every time you water as allready mentioned.

I leave the fan on 24/7 and pulled out the old dehumidifer from the attic, have it set to 50% near the grow room and haven't had a problem... even after my dumbass rookie (gulp) overwatering scene.
