Are there any systemics that people use for mold? My grows always end up with mold in the top colas. I dont have control over humidity when growing outside in a greenhouse.
i grow outdoors in a greenhouse during winter. it gets down to the 40s at night and makes the purple plants turn extra purple. my other plants are full green. its all in the genetics, a cold temperature wkll only turn a plant purple if it has the purple gene.
